I had to

Couldn’t pass up this post, which is going to be long without being wordy. I know you don’t believe me, so watch carefully.

Some of my resident mantids have gone missing for the past week or so, but the brown one returned last night. This evening at dusk, it had no sooner ventured out than it snagged a leafhopper meal, and I was able to capture a sequence of it knocking back this repast.

I know, not half as much fun as the equivalent column space full of text, but hopefully still entertaining. I even got a scale shot so you can see the growth, especially when compared to this post (note the leaf sizes.) My shooting angle slightly blocked the light, but when I shifted position to try again, I spooked my model into hiding.

It’s fun watching them grow up, but also a little sobering. Out of a dozen or so that could be found when they’d first hatched, I can now spot only two dependably. Moved on? Became a meal for something else? Cannibalism? I haven’t witnessed any of them come to an ill fate but remain confident that most have – that’s how it goes.

On composition, part 18: Illustration

If you've ever wondered what makes the clusters of foam seen on plants sometimes, it's this spittlebug nymph, shown in the process of hiding itself
If you’ve ever wondered what makes the clusters of foam seen on plants sometimes, it’s this spittlebug nymph, shown in the process of hiding itself. This illustrates behavior, but not anatomy too well.

This one was inspired by this recent post, but let’s look a little closer at using photos for illustration.

While all of photography might be considered illustration to some extent, there’s also a more specific purpose, separating it from genres such as portraiture, journalism, art, and so on. If it helps, the idea is to visually represent something explained in accompanying text, or provide a good example for identification. Advertisements, of course, provide illustrations of their product, and some images are aimed not just as displaying some subject, but invoking a mood or environment at the same time.

Yet, those ‘excluded’ topics above can also be illustrative in many ways: a portrait can include elements of hobbies or interests, and photojournalism often provides a portion of a story. Even tourist shots can fit the bill if one thinks in the right terms. One thing I often tell my students is, the photo stands alone. It doesn’t matter how hard it was to get a particular shot, or how limiting the conditions were (even those these can make good backstories); the image is strong or weak on its own, without excuses or explanation. The same can be said for choosing what and how to shoot; does the image convey the conditions or locale adequately? Does it give the intended impression? If someone sees just the image, how much can they infer from it, and does this match with your expectations as the photographer? Note that your expectations are not necessarily to be accurate – it’s just fine to give an impression that belies the reality.

The hardest part of this is recognizing the subconscious cues we can take from images. Overcast skies reduce the reds and yellows, the contrast and distinct shadows, and so we’re able to spot images taken in such conditions – even when we can’t always put our finger on why we get this impression. Shadows can produce certain moods, especially in how they fall across faces. It can take time to realize what factors are at work in our own images, and the best advice I can give is to look at a lot of photos, especially the ones that provide the strongest feelings (good or bad,) and try to pick apart what visual aspect produced the effect. Imagine it in different light, or with a different background; plot the colors you see, not the colors you interpret.

All of that reflects how any image can be an illustration, something that evokes a mood or tells a story. But what about the very specific uses mentioned earlier, where the point is to give a visual to the story or text? What are the more effective ways of going about this?

A position that shows the subject and the display, in low-contrast light that permits the display to even be seen, and the proper way of holding the camera; this was all carefully planned.

The first thing, obviously, is to know how and where it will be used. This is easy when you’re writing the accompanying text yourself, much harder when you have to match another person’s work (especially if, like with many publication sales, you have only a brief description from an editor regarding their needs.) Some genres or subjects actually have preferred approaches; a plain white background for arthropod and botanical images used solely for identification, for instance. Yet other uses may demand a natural setting, a demonstration of some behavior, or even matching the mood of a piece. This is hard from the standpoint of producing a stock of images for multiple uses, because it means shooting any subject (often, as many as you can) with an eye towards this broad spectrum, which translates to lots of images with different approaches, variations of setting and lighting and angles, and loads of time spent. It’s little wonder that many photographers choose to specialize.

Knowing your subject can help a lot. If there’s anatomy or behavior unique to a species, flora or fauna found only at this locale, even a particular style favored by this artist, then you know what to try and illustrate, at least. Very often, simply catching something happening puts you ahead of the game, because the image is no longer just “this,” but a slice of life – I know I’ve shot more than a few images of behavior I didn’t recognize at all, to research it later (and learn something in the process.) This approach doesn’t let you prepare as much as would be ideal, which I’ll touch on shortly, but at least you’re getting something that could be used in more places than just a ‘portrait’ of the subject.

The ability to portray a subject in different ways is useful, and again, this may take looking at a lot of images to get the feel for it. Food illustrations are often in soft, yellow-orange lighting in a cozy setting, communicating relaxed and comfy – imagine how poorly it would work to see food in a clinical setting instead. Product photos often go for dramatic lighting and angles, even using lens distortion to enhance the perspective. Travel images (I know this will come as a shock) display ideal vacation weather, but think about this for a second: the photographer not only had to be present for the right sky and clouds and surf conditions, but have the light angles pinned down and just the right amount of attractive ‘tourists’ in the shot. Illustrations often rely on what’s not in the image to help sell the idea.

An aquatic snail in the process of laying eggs - the light angle and quality needed to be just right to show both the shape of the snail's body and the outlines of the eggs themselves.

Lighting is huge. Of course you want the right light on the salient details, and this sometimes takes no small amount of effort, especially when photography produces higher contrast than we see when viewing the subject, and detail can get lost in shadows or washed out by being too bright. It’s no secret that good photographers often have a wide variety of lighting options at their disposal, with some really esoteric devices like grids and barn-doors (I’m sorry, I’m not going to go into how these work right here, but some other options can be seen on this page.) It’s almost a science to produce a photo with controlled lighting that nevertheless looks perfectly natural. But there’s also the technique of using lighting for drama, as well – backlighting to produce mood or an ‘aura’ that highlights the subject, shadows that shape someone’s face for a sinister look, even a subtle ‘spotlight’ effect that illuminates the subject while leaving everything else faintly darker. And never forget that it’s shadows that give us shape and textures from a two-dimensional photograph, which means using the light angle to your advantage.

Not surprisingly, if you intend to illustrate something, it should be very clear and distinct, yet you might be amazed at how easy it is to miss this. Backgrounds should be undistracting yet appropriate; key details should have good focus and necessary contrast (which means not too much or too little.) For instance, insect wing veining shows up against a brighter background, but the iridescence from the transparent membranes requires a darker one. Shooting from eye-level is enormously helpful for any subject that has them, from pets to children to reptiles – it’s no surprise that I crawl around or climb on things a lot, but every photographer should recognize the value in this.

Which leads into the next part: take a lot of images. Subtle variations can make large differences in the overall effect, and some things may not be immediately apparent in the viewfinder or even the LCD preview, especially if a flash is being used. It rarely hurts to approach the illustration in multiple ways too, if possible – choices are never a bad thing. This doesn’t just mean layout, but also consider changing focal lengths (which can affect distortion and perspective,) aperture (which affects background blur,) lighting color, and perhaps even the mood or setting you chose initially.

Depending on how serious you are about illustrations and how often you might have to tackle them, you may end up needing a lot of equipment – lighting and its accessories foremost, but also backdrops, props, braces and supports, and so on. I have several items I use for mini-studios for insect work, and I’d have a more dedicated studio if I had the space (mostly to save the setup and teardown time.) I’m always focused on the money-saving end of things and rarely see any need to pay for professional equipment when anything else can be used instead – my reflectors are often sheets of paper or matboard, diffusers are fabric or white plastic bags, and supports are stiff wire with alligator clips attached. Such efforts apply very well when you only have to produce illustrations on occasion.

The more you do it, the more techniques and tricks you learn, like using petroleum jelly on plant stalks to prevent an insect subject from passing a certain point, stretching a bit of nylon stocking over a lens for a soft-focus effect, or putting small items on a lazy-susan turntable to change shooting angle easily – a variety of different books to stack beneath changes the height quickly too. Very often, you’ll be forsaking spontaneity for staging, candid for controlled – not everyone likes this idea, but it’s hard to produce good illustrations, routinely anyway, without it. This is where slowing down and considering the end result provides the greatest impact.

You don’t look a day over eighty

So not only is today the summer solstice, but also World Humanist Day – which is, admittedly, an odd thing. Not in that I believe we shouldn’t bother with it, but in the implication that there’s only one day to consider or celebrate humanism. It’s like having a National Don’t Set Your Neighbor On Fire Day; it’s something that we shouldn’t need because it’s automatic. But perhaps the main idea is a day to promote the awareness of humanism, and if so, I can handle that.

Secular humanism is the ideology that we can determine effective moral, ethical, and social guidance without resorting to any religious, supernatural, or spiritual influence. While it is often confused with atheism, there’s a distinctive difference: it’s possible to be an atheist and not give a damn about social welfare. This attitude is remarkably rare, however, so the crossover between the two is common, but this distinction still appears in odd ways. Religious folk desperate for a way not to lose another argument will often point to the dictionary definition of atheism, as if this renders all socially-based arguments from an atheist null and void – apparently there’s a belief that a label must be exact or it’s irrelevant. I’m quite direct in calling myself an atheist, even though ‘secular humanist’ is far more accurate (and ‘critical-thinker’ even more so); besides the fact that far fewer people even know what the term means, calling myself a secular humanist sounds both pretentious and like I’m shying away from the negativity of the word ‘atheist.’ It’s my small way of saying, “Fuck your feeble preconceptions.”

The first usage of the term, according to Merriam Webster, appears to be from 1933 – surprisingly recent, given the long history of the overall concept, which can be traced back for thousands of years. In fact, the actual origins of it may predate every form of religion on the planet. But let’s start from the other end.

We are assured, so often that it’s practically a cultural assumption (at least in the US,) that religion is the source of all morality, and even forms the basis of all laws. When it is pointed out that scripture is remarkably weak on countless concepts of morality, and outright contradictory to others, it is usually asserted that the gist of scripture leads the way – laying the foundation, if you will. There are so many ways that this fails I can’t possibly enumerate them all, but I can provide a representative few. Women’s rights not only lack the barest hints of either existing or being recommended, abrahamic scripture is very distinct in considering women both chattel and unimportant beyond the baby-making angle, something that still exists in countless sects today. Such a basic thing as equality among humans is directly denied, from the sins and low origins of other ‘races’ (there’s just one race, which explains why we can interbreed) to structures like caste systems and chosen people. Followers are openly instructed to beat children and stone heathens and pillage wantonly among the lesser folk. And should anyone wish to claim that these were radical misinterpretations of what scripture really says, we need look only at the long history of holy wars, religious persecution, and declared privilege to determine that the true message was lost on so many people that it defines the most inept body of law in the universe – in fact, actively and repeatedly achieving exactly the opposite of moral guidance. Hiding behind “the fallibility of man” is a feeble excuse; this supposed guidance was directed at us, created to be this way. The message that can be taken from this is that we are intended to run rampant – if we bother to accept such nonsense assertions.

This also means (and this is not an atheist manipulation, but a direct assurance from countless religious folk) that without religious guidance we will descend into self-absorbed, nihilistic behavior, often compared to the “beasts” (another factor in decrying evolution, by the way.) I’ll take a moment to point out that the social structure of many “beasts” is superior to our own quite often, especially when it comes to slaughtering members of the same species. Yet what especially needs to be noted is that every culture developed their own moral guidelines, remarkably similar in more ways than religions have ever managed, and the further any culture gets from reliance on religious authority, the higher its social standards and general well-being. There’s even a study that religion and racism are closely tied. True, this does not mean that religion causes racism, and I’ll be direct: religion is very often just one manifestation of class consciousness, racism being another. But since we’re talking about the moral imperative of religion, we should expect to see much lower levels of racism and higher levels of social harmony. It becomes obvious when one bothers to check: religion isn’t providing much of a guidance.

The question of where moral behavior does come from was the topic of my first “But How?” post – we’ve always had it. It’s the benchmark of a social species, and as such, found in far more than just Homo sapiens. Species that gain a benefit from any kind of group behavior must have cooperative functions, and even see social interaction in a positive light. This is such a fundamental trait that even some species of insect, like ants and bees, possess it; it boggles the mind to think that we would need to learn such behavior.

SquabbleAnd yet, there’s the negative behavior above to consider – just as obviously, the internal guidance wasn’t working too well in the bad cases throughout history. Mostly, this is because it’s not the sole behavioral trait we possess; competition is also pretty strong, and since these are in conflict, there must be some ‘criteria’ for when one or the other is to take precedent. I put ‘criteria’ in quotes because the word implies a much more elaborate structure than what our brains would actually possess. We have strong familial bonds, protecting our spouse and offspring, and these get weaker with the ‘tribe’ and vanish entirely against any perceived threat. So there’s quite a bit of subjectivity about our in-groups and how we interpret anyone as “fer us or agin’ us.” We know that it’s good behavior to favor our in-group against any outsiders, but the method of determining where these lines are is vague. Most religions are remarkably adept at drawing lines, relying on such manipulative concepts as the perfection of the self (“saved,” “chosen,”) the idea of ultimate authority, and of course ideas such as there being One True Religion™ – no need to prove any value or superiority, just proclaim it. Very self-indulgent, but hardly a guideline for moral behavior. As a species, we’re not very good at distinguishing the desire for social cohesion and the desire to feed our egos (another nail in the coffin of the “designed” idea.) Our penchant for drug addiction makes it clear that it’s too often the good feelings that count, not necessarily how we achieve them.

Any immaterial justification for any behavior is going to fare as badly – it’s far too easy to create something that supports our pre-existing views without fulfilling any other function. See if you ever run across someone who announces a spiritual property or “way of knowing” that they themselves do not possess or that fails to boost their ego – good luck with that. But various scholars and philosophers throughout the ages have argued that morality really should be about more than indulgence, one set of guidelines able to apply to everyone without drawing lines. Crazy talk. Even a cursory examination of our Constitution reveals (to those not scared of the idea) a basic principle of equality, fairness, and the reduction of privilege, though it was soon realized that they didn’t specify the dismissal of religious authority within our government, correcting this with the First Amendment. And of course, this whole idea forms the backbone of secular humanism.

It’s not hard to find people claiming that the goal of secular humanism is to eradicate religion – only religious people though, imagine that; I always thought honesty was one of those important things to them, but whatever. Secular humanism, however, only affects religious privilege over others – it destroys pedestals to bring everyone to ground level. No secular humanist would be any more valued or privileged than any member of any religion, and no less answerable for their actions either. Decrying this can only come from someone with something to lose from it, angry that they would be considered as morally responsible as everyone else. A whole orchestra of the world’s tiniest violins has sprung to life…

It could be argued that, if we are born with a socio-moral objective, there is little point to humanism. It could also be argued that humanism is simply attempting to do the same thing as religion – there have even been attempts to have it declared a religion, though what purpose this would serve is unclear, except for leverage in the weird legal system we have over where religions can and cannot appear. So we’ll take a look at both of these, in reverse order.

The definition of religion has always been up for grabs, though legally it is specific enough to rule out humanism, and of course the bare meaning of the word “secular” also puts the kibosh on the religion angle. There seems to be some difficulty with telling the difference between a religion and an ideology; humanism is an ideology, which means it forms an underlying approach or attitude towards decisions and actions. Every form of government is an ideology, as are cultural standards for schooling.

Tackling the former argument about not needing an ideology for social and moral structure, the points above should have made it clear that we have tendencies towards social cohesion, but a hell of a lot of ways in which we get confused, sidetracked, or deeply involved with disguising indulgence as morality. While better than nothing (especially the nothing that the religious insist we would have without their stalwart help,) it’s still a lot worse than we can imagine. Evolution doesn’t always produce strict behavior, but nudges in useful directions – and there are a lot of nudges for a lot of different circumstances in our complicated lives. Not to mention, if we were as dependent on our rational minds as we like to think we are, drug addiction and sexual affairs and arguing over music wouldn’t actually occur at all, much less all the fun we tend to have over how to define and regulate moral behavior. We really do need something that we all find as agreeable and functional as possible, that we can resort to when there are doubts. Hold that thought, because we’re going to come back to it.

Secular humanism, for the most part, isn’t about creating rules, or dictating behavior. It’s about producing a perspective, an underlying concept of what a goal should be, that gives structure to rules and decisions. Someone driving in a residential area does not need a speed limit sign to infer that the limit is probably much lower than the freeway – traffic is thicker, more opportunities for people to pull slowly out into the road, and bicycles and children are far more prevalent. The structure behind all this is, “It’s far more hazardous so stopping distance and reaction time are far more important.” I feel safe in saying most drivers understand this perfectly well – but a few too many think that it somehow doesn’t apply to them, or that a temporary exemption just for them should exist because it’s inconvenient otherwise. Self-indulgence; it’s not that it makes sense, it’s that we’re a species that is adept at manipulating things to our individual advantage. This perspective, this glaring realization of how egotistical we can be, is but one aspect of humanism.

Most notably, secular humanism eliminates (or at least greatly reduces) any reliance on broad labels, pronouncements, or assertions. Good and evil are not properties, but indefinable abstracts; there is no action (much less person) that can be said to be universally good – there is always some way in which someone will fail to benefit from it. Decisions based on the promises of post-mortem states are ludicrous when we have real-world, demonstrable, and above all dependable consequences that are easy to see. Morality is solely about other people, how we interact and the importance of functioning socially – otherwise why would anyone care in the slightest? To make any claim (as many religious folk indeed do) that morality is only about how one appeases their deity not only makes it a pointless concept to promote, it inevitably produces exactly the hedonistic nihilism that is supposed to be so horrifying. “I am good, you are not; since you’re going to hell anyway, let me hasten the process.” Lest anyone thinks this is a straw man representation of religious viewpoints, let me remind people how often phrases such as, “Kill them all and let god sort it out,” are still heard, and how angry evangelists tend to be, and that religion has been used as a justification/motivation for war for nearly all of written history (how many religions specifically chronicle the wars they’re most proud of?) If we think this isn’t accurate anymore and such historical behavior is behind us, it is only because of the secular influences that our culture has been promoting, and increasing.

We can look at scriptural exhortations to stone women who talk without men’s permission and say, “Damn, that’s stupid!” – because it makes no sense. We can create laws against driving while intoxicated, not because there is the faintest religious backing for it in any way whatsoever, but because we know what the consequences are, and find it remarkably unfair that someone far removed from the complete idiocy of alcohol can still come to harm because of it. We can contemplate laws restricting same-sex marriage and say, “Hold on a second – isn’t this creating a double-standard, where a legal practice somehow becomes illegal based entirely on who engages in it?” (Note that I said we can, not necessarily that we do.) And this means we can pause for a second and realize that laws are to prevent harm, not to reinforce someone’s pointless prejudices. That’s secular humanism; guiding our decisions through the application of objective, rational perspective and observable consequences.

Yes, this does mean that secular humanism can actually be pursued by religious folk, as well – and it is, more often than we might think. The laws in this country regarding freedom of speech and freedom of religion, including the ones protecting religious observances as special cases (look up animal sacrifice under santeria, and how kosher foods are classified,) demonstrate that secularity is not anti-religious. And I’ll openly admit that there is a difference between what someone wants to use as their personal worldview, and what they should be pursuing as standards for everyone. Religion is stupid, self-indulgent, petty, and dangerous – it is the dumbest thing any culture can ever embrace. For the record. Yet, making a law against it would be both pointless and oppressive. It’s up to people to make the decision on their own, and my part, placing value in fairness and reason, is to make the case about how stupid religion is, trusting in people to have working brains. If I cannot plead my case convincingly, perhaps it’s not strong enough.

[For anyone who reads that and smugly assures themselves that I haven’t convinced them to give up religion, that’s quite all right; the ball’s now in their court to try and convince me to take it up ;-)]

SocialAbove all, humanism recognizes that the primary focus is the human race, and not whatever subgroup anyone places themselves within. Distinctions about nationality, or skin tone, or sexual preferences, or what is eaten for breakfast, are only methods of feeding ego, of drawing lines that place us on the good side. Don’t get me wrong; lines are undoubtedly beneficial, when drawn in a functional way, such as between the greater populace and rapists. Humanism uses social interaction, and empathy, and a generous helping of demonstrable consequences as its primary guide. It helps reduce the emotional influences upon what we do, especially regarding others, and substitutes careful consideration instead. True, one can argue that empathy is an emotional influence (especially if their goal is to challenge anything they don’t like rather than fairly consider it) – but empathy, or what it produces, is also a considered response: we rely on social interaction as a species, which requires fairness, trust, and mutual benefit. That’s why we developed it.

The only people who argue against these standards, don’t; they inevitably misrepresent humanism in fatuous and wildly creative ways, mostly to (and I hate to sound like a broken record here) feed their own ego and maintain their own privilege. It’s pathetic, and ironically, it’s exactly what those standards are intended to move mankind away from, and in doing so, ahead. We already know selfishness isn’t very beneficial – we just need better skills at recognizing it.

And with that, we return to the comment made above about a system that we can resort to when there are doubts. Because another aspect of secular humanism, also represented quite well in critical thinking, is the ability to evaluate our social structure objectively – to actually have doubts. It’s very easy to think in terms paraphrased as, “I’m happy with it, so what more is needed?” Obviously, this is hardly a functioning method of defining morality – which makes it all the more astounding how often it appears in cultures. There remains no small number of people who believe that a majority vote defines the ‘best’ approach to laws and governing, never comprehending what laws and government are actually for. Or those who believe that a right is something that should apply to one group of people and not another. Both of these fall under a concept called, ‘the tyranny of the masses,’ other times simply referred to as, ‘mob rule.’ There are enough historical examples of how this leads to bigger and nastier mobs that it’s pointless to reiterate here, except to say that less attention should be paid to the culminating events and more to the underlying attitudes that fostered them – treat the illness before it irreparably damages the body.

It’s entirely possible there is, or will be, some better method of approaching social and moral structure – though it’s hard to imagine how, to be honest. What has been demonstrated throughout history is that secular humanism far exceeds any other approach we’ve tried, and provides the structure for the greatest benefit and the highest function. So on World Humanist Day let’s at least recognize what it’s accomplished for us so far, and consider what it may yet accomplish in the future.

Meaningless milestone number, uh, whatever…

DelicateFittyThou-s
Today, I shot the 50,000th image on the old Canon 300D/Digital Rebel. That is, since I’ve had it, anyway – I got it secondhand, so from its own personal standpoint, well, I got nothing, since it’s a piece of electronic equipment and doesn’t have a personal standpoint.

Mind you, this is not the 50,000th image I’ve taken, because I passed that long ago, nor the 50,000th image in my stock. It’s way under the 50,000th insect image in my stock; I have a ways to go on that end (I am somewhere in the realm of 11,000 images there.) The best I can say is, there’s a certain amount of luck involved in this being not just a keeper, but one I can feature in a post. I’ve spoken at length about the trials of macro photography, and chief among these is that I miss a lot of shots (I suspect most photographers do in the same circumstances, but I can speak on authority only for me.) The image immediately before this is getting tossed out, along with a lot of macro stuff – the zone of sharp focus is very short, as can be seen from the larger version you’ll get if you click on the image, which means that anyone wielding the camera who is not perfectly steady can twitch out of the focus range at the crucial moment. Ahem.

This is a thread-legged bug, or thread-legged assassin, or perhaps several other common names as well, so the dependable moniker is Stenolemus lanipes. Body length, proboscis to wingtip, is roughly 13mm. Obviously, spotting something that looks like a bit of lint involves a bit of luck itself, unless for some odd reason you find it on the kitchen table as I did this one (it’s summer in the south – it happens.)

BadassFoofooAnyway, you may virtually join me in this non-celebration of our species’ peculiar obsession over evenly-divisible numbers from a base-10 system, even though the image I’m showing to the left doesn’t count (“count,” a ha ha, you missed it didn’t you?) but I still like the perspective better than the above. What the two shots illustrates, though, is how with such a short range of sharp focus, trying to get as much of your subject within that range means some selective shooting angles (such as the full profile approach at top) or deciding on exactly which anatomical feature should get the attention – unless you have a very good reason otherwise, it should be the eyes, just to provide a hint. The sneaky bit that can come into play is finding a way to have both the eyes and some select other feature in the same plane, such as the forelegs here (I admit this time it was more chance than design, since insects are abysmally bad at taking pose advice. But never admit that. The blind luck in getting decent images, I mean – you can admit to the intransigence of arthropods to your heart’s content. It’s a lot of fun.)

As a final note, this is the kind of post I won’t use for a podcast, partially because it has illustrations, but mostly because there’s no way I will inflict having to say “thousandth” multiple times on myself. Seriously, what total moron came up with that consonant combination?

Getting there

HumidityAtTheGatesI’m starting with an image largely unrelated to the post topic, simply because I like it better. I did get a few dewy morning photos of the plant I’m about to mention, but this one’s much stronger, and it does illustrate the conditions nicely. Just don’t call it art.

In the attempt to get nice natural settings for subjects like hummingbirds (who are raiding the feeders madly right now,) I’ve tried cultivating several different kinds of flowers to attract them. Most simply didn’t take well. The salvia blooms have been too small. And the birds aren’t showing any interest in the butterfly bush (probably Buddleia davidii), though it’s now gaining the attention of a few other species, so it’s starting to fulfill its purpose. Plus it’s National Pollinator Week, which had escaped my attention until this post was in final draft despite the fact that it fits nicely…

The other morning the dew was off the charts, plus it had gotten surprisingly chilly overnight. The bumblebees (best guess is Bombus bimaculatus) had been plundering the butterfly bush routinely, and a few had decided to camp out overnight on the blossoms – the result was several soaking wet, extremely sluggish bees in the morning. This allowed me to go in for the closeups without frightening them off, though it did engender some leg-waving warning behavior. As I was getting sharp focus, I could see something moving off to the side, too small to make out clearly, which turned out to be an unidentified insect who’d warmed up a lot faster than my primary subject, and was scampering about without regard for personal space or proper decorum.

Socrates
Below is a tighter image for the detail, letting you determine that this is a female. What? You mean you didn’t know that twelve antenna segments denotes a female, and thirteen denotes male? That’s okay, because neither did I before I started this post – I end up doing no small amount of poking around just to try and give proper scientific names, which can get very involved with arthropods. Anyway, females only have twelve because god used one to make the males, or so the story goes. Makes perfect sense…

PassTheTowel
It’s a shame that this resolution doesn’t let you see the detail within the compound eyes, because I did capture it, but for the blog image size it was either good framing or closeup detail – I chose framing. This time.

A little later in the day, I noticed that a bumblebee moth (Hemaris diffinis) was visiting the bush, and I hustled inside to get the camera, lucking out considerably in that the moth was still busy when I returned. Usually I spot this species, and its kin the hummingbird hawk moth, fleetingly, and have less than a minute to get anything decent in the way of images. This time around the moth seemed perfectly willing to ignore me, and I was even able to chose my shooting angle occasionally.

Diffinis-1
Unlike bees and most lepidoptera, hawk moths don’t land to gather nectar but remain hovering, and of course this isn’t perfectly still either, so tight focus is a challenge – I should not have the number of useful images that I do. Even less so because I was on the phone the entire time (hands-free headsets are wonderful things) – my friends are used to this, to be honest, and even offer advice. One suggestion that I received, which seems to make perfect sense, actually doesn’t work: you can’t select a spot and wait for a bee or moth to wander into it, because there’s nothing systematic about the way they gather nectar. I’ve tried this a lot, and have been successful only a tiny percentage of the time, and certainly not with the Hemaris.

Diffinis-2
This image seems like a somewhat boring angle and framing, until you realize that the proboscis can be seen going straight down into the bloom – I’m pleased. A curious thing that I noticed during the shoot was that the bumblebees were smaller than I often see them, only about 25mm long, but the hawk moth was the same size, significantly smaller than I’ve ever seen one. I have no idea if this is just by chance or if there’s some natural mechanism that helps them blend in as closely as possible, so they appear most often among bee species of similar size.

Diffinis-3
I might have to look up the properties of the Buddleia flower genus, because all of the insects that were visiting the blooms were the most intent I’ve seen, disturbingly so. I was able to pet a bumblebee (showing off for The Girlfriend) without producing even the slightest reaction, during the heat of the day when torpor was no excuse, and my friend the hawk moth was so close it actually passed within 3cm of my leg, while I was sitting on the ground and looming over it with the camera and softbox. That nectar seems to be heady stuff.

I’ll close with a detail crop of the previous image, to show just how lucky I got this time around. While I might have liked a better contrasting background or to have caught the wings in an ideal position, I can’t knock the focus on the eyes and proboscis. If there’s anyone out there that mutters disparagingly over my use of captive subjects and studio shooting, this image, taken of a hovering, hyperactive insect, is my “Bite me” response ;-)

A few years back when I was still following the Bad Astronomy blog, Phil Plait posted an image of odd geological features on Mars, along with the current speculations as to how they had occurred – which were not quite fitting the visible details. Definitely read the post for the salient bits, but long story short, the idea that subsurface deposits of frozen carbon dioxide sublimating into vapor, which would vent upwards and cause the overlying sand to fall away to the sides, would have produced a fanning effect at the ends not visible in the images.

This is the fun of using photographic surveys of other bodies in the solar system. Often planetary geologists have just one photo, from one angle and one lighting condition, to try and puzzle out what kind of feature they’re seeing. It’s not something that comes up often, since us laypeople generally see images of very familiar things, but the two-dimensional trait of photography can produce lots of peculiar impressions. We can’t shift slightly to the side to see how the shadows or perspective changes, we can’t use the inherent depth perception of our two eyes, and we can’t even be sure we’re seeing a real shadow or simply an area of darker material. A gully or a ridge can look exactly the same with the light coming from opposite directions, so often it’s not just a single feature that needs to be examined, but all of the conditions surrounding it.

I’m not going to even imply that I have anywhere near the abilities of those who evaluate geological images professionally, but I have done a fair share of photographic examinations, sometimes to detect hoaxes, but also just to tease out illusions. It helps to know that, for any given shape, texture, or geology, light direction tells us how oblique a surface is to the angle of light. In other words, if we imagine ourselves traveling in the same direction as the light falling onto a shape, whatever turns “uphill” to us will become brighter and more reflective, and what turns “downhill” will become dark, maybe even fall completely into shadows since it’s “out of sight” over the ridge. So, I had stared at the sample photo for a while before posting (at that time, under the nym “Just Al”):

I don’t know – looking at the first image under higher res and additional magnification, I suspect something else entirely is at work here.

Look at the shadows of the central large furrow, and most especially to the right of it. Unless I’m misinterpreting them, that furrow is actually running a ridge line, and while it turns downslope slightly (lower right) it then turns away. That somehow doesn’t seem right.

The other thing that seems counterintuitive is that the furrows, nearly all of them, show pushed-up edges on both sides. This might simply be an artifact of crosswind sand deposits, but it doesn’t seem likely that this would occur on both sides. Fluids digging furrows don’t typically push up deposits on both sides unless they’re moving pretty fast, and then they display turns with greater washouts and “elbows.” They also seem unlikely to peter out so abruptly without either fanning or “pointing.”

The lack of points also seems to rule out some kind of erosion “slipping,” the crust cracking and splitting towards the downslope side – the ends shouldn’t look like that.

Then there’s the idea that when the forks come together, the channels don’t widen, seeming to indicate that the channels were carved singly at different times.

Now, here’s what’s occurring to me right now: is there such a thing as a CO2 glacier? Because this seems to fit the furrows closer than anything else I’ve thought of so far, and the cohesiveness of a glacial body might prevent sideslipping a bit. Not a perfect idea, I admit, but the best I’ve come up with so far…

I don’t maintain regular access to planetary and astronomical studies anymore, and so wasn’t following any new developments in this area, but today’s Astronomy Picture of the Day was a nice little vindication.

A leading hypothesis — actually being tested here on Earth — is that these linear gullies are caused by chunks of carbon dioxide ice (dry ice) breaking off and sliding down hills while sublimating into gas, eventually completely evaporating into thin air.

(Where the hell did the idea of huffing on your nails and polishing them on your shirt come to indicate smugness? Regardless, I’m doing that like an annoying bastard right now.)

None of this is proven yet, of course, and won’t be until we find an actual chunk of solid CO2 plowing its way along the Martian landscape. In the meantime, I’ll be happy to offer my services to the Jet Propulsion Laboratory – for a hefty fee, I think it goes without saying…

Just more arthropods

EyedClick
We’ve been seeing some steamy weather lately, high heat preceding wicked thunderstorms, and I was dumb enough to go down to the river in the former looking for subjects. Between bad sinus reactions and sweating buckets, without finding much of anything to shoot, I elected not to stay long. But I did bring back an eyed click beetle (Alaus oculatus) to get some more detail images of. These are among the largest beetles to be found in the area, this one hitting about 50mm, and completely innocuous. I had been hoping for one of these when doing the illustration for the Brain Bugs book review last year, but never located one.

Apheloria
The only other species I saw was an Apheloria virginiensis montana (I believe, anyway, though mine sported only faint dorsal spots, unlike every identifying image I’ve found for the species.) This one’s just a wee bit longer than the beetle above and fairly common around here, even though they don’t appear to have a common name. If you’ve ever heard the old chestnut about the smell of bitter almonds indicating cyanide, and wondered what this actually smelled like, handling one of these will provide the experience. Accurately, as well – they really do produce a cyanide compound as a predator repellent, so at least wash your hands immediately afterward. Those bright colors are yet another example of aposematic coloration, high-contrast warning colors to make the species memorable and easy to spot, once an unlucky predator has been unfortunate enough to get a mouthful of nasty secretions.

Quite a few species exhibit these traits, all utilizing the same basic combination of distinctive, contrasting colors and discouraging response; essentially, the repelling method creates an indelible learned memory, even in species not particularly known for reasoning skills, and the colors are distinctive enough to get connected to those memories, so predators learn that festive colors do not promise a good time. I had originally suspected that somehow, many species automatically recognized bright colors, because the learning method seems rather inefficient; most predators can do a lot of damage before any defensive response could take effect, meaning the organism could die despite their defense – it seems unlikely that this system could evolve effectively. But then there’s the problem of just how any predator would have evolved the idea that bright colors mean something bad in the first place, as well as the fact that any species would only have to develop the bright colors to protect themselves, and not any other form of defense.

ApheloriaMiteCarl Zimmer talks about this trait among poison arrow frogs in Costa Rica, which display significant color variations within a surprisingly small geographic area. Be sure to read the comments for more speculation about how the process works for these amphibians. Meanwhile, one of the images I got of my multipedal subject showed an enterprising mite traipsing across the cranium (as well as some spiderwebs.) This is the best image I have of it, unfortunately – the millipede was scaling the vertical concrete walls of the spillway, and I was standing on the submerged apron aiming straight down rather awkwardly while my subject was wandering unpredictably. In short, there weren’t a lot of options at hand for those conditions. The mite was discovered only after unloading the images once back home; I couldn’t have possibly spotted it in the viewfinder, but even if I had, I doubt I could have done much about it. It was bad enough getting the focus on the bobbing head of the millipede, without trying to catch the mite in its own perambulations…

DifficultMimic2
DifficultMimic1A few days ago, I’d managed to capture another specimen I’ve been wanting more images of, an ant mimic jumping spider. Only about 5mm long, they really do appear like ants unless you know what to look for. For instance, they only have two body segments – spiders have a fused head and thorax, called a cephalothorax, while ants do not – but to me, it’s easier to spot them from their habits; spiders just move differently from ants. Especially this species, which is highly active for a spider and very difficult to capture in the tiny focus range of macro photography. These images were from my second attempt, the first yielding nothing worth keeping. And these are admittedly studio shots, using a sprig of grape buds held in an alligator clamp, with a little petroleum jelly on the base of the sprig to prevent the spider from escaping (on foot, anyway – there were a few tries at rappelling down on a web strand.) The background is a photo print, close enough to be lit by the same flash and softbox. While I could try to photograph this species in the wild, I know I would achieve nothing except drastically shortening my lifespan through stress and frustration. Police investigators now know, if they find someone dead in a field with a camera nearby, to check and see if a macro lens is attached. If so, the ruling is simply “natural causes” for nature photographers. And you thought the biggest hazards were bears and hippos…

EvilMimicAll of my attempts to pin down this species have failed so far, but I’m leaning towards a member of the genus Synemosyna. Anyone who can help out is invited to comment, or contact me directly – I may end up submitting them to BugGuide.net to see what their crew has to say. Meanwhile, this image remains my favorite, not because of any professional reason, but because the secondary strobe I was using for fill lighting provided a great sinister effect when the spider peered down in that direction – I suspect this is aided by the creepy position of the forelegs. What’s really happening, I believe, is the arachnid is collecting strands of its own silk and consuming it – this is a recycling trick of spiders (one of these days I’ll branch into video, but I don’t imagine that reducing stress in any way at all.) You can also see evidence of this same lighting technique in the first spider pic above, but I wasn’t using it for the second. Note the different reflections in the eyes, between the overhead softbox that illuminates the body chitin smoothly and the sharp reflections from the mini-strobe placed well below. While this subject might have benefited from the white box technique, I’ve had a lot of issues using that with reversed lenses, which pick up too much glare (lens coatings and structure are designed for using a lens the right way around…)

ThirstyAssassinMy final subject is another specimen provided by The Girlfriend, who spotted it on her car and quickly captured it within a film can that she carries for expressly that purpose (yeah, I know, I’m a lucky little shit.) There is a chance this is actually the same species that she caught last year, just a much-younger nymph stage – still working on that bit. I initially considered it an assassin or wheel bug, judging from the body shape and proboscis; suffice to say it’s an Hemipteran (True Bug) who took advantage of some dew while I was set up to get the shots – every once in a while you get some nice cooperation. The spot in the eye is not evidence of my lighting technique, even though I just taught you how to look for this, but a pollen grain instead – another clue is that there are no other sharp highlights on the front surface of the legs, proboscis, or dewdrops.

I’ll close with a scale shot, purposefully done this way because it communicates the size so much better than giving length in millimeters – and because this was the only specimen that cooperated enough for an easy shot. The spider was many times smaller than this, while the click beetle and millipede were both about the length of my little finger. It provides an idea of the range of magnifications possible when pursuing arthropod images – which also indicates how much can be missed without looking closely.

Is “natural” a good thing?

This is another of those ponderous, philosophical posts – I’ll try to follow up with pics and fewer words soon, I promise…

Given that we understand that evolution by natural selection is effective, in sometimes astounding ways, but also a bit haphazard and imprecise, questions sometimes arise about whether conscious decisions might be able to accomplish better results more directly. This subject has been tackled many times before, very early on actually, and one of the most loathed methods was the process of eugenics, practically a curse word in today’s culture. Yet the fundamental problems with the eugenics program(s) weren’t the goals, it was the huge misunderstanding of what genes can produce (as opposed to the post-genetic factors of upbringing and culture) and the methodology involved, which at times violated human rights and common decency. The movement also encouraged the common idea of being superior and privileged solely by existing, or to be more specific, solely because one was better genetic ‘stock’ than someone else, making it easy to be abused by our fragile egos.

The thing is, this concept of genetic superiority is actually quite valid, if one is careful to define their criteria and fully understands how the process works. Certain genetic variations do indeed produce organisms better suited to their environment than others, and the advantages incurred translate into better survival/reproduction and thus greater spread of those genes – this is entirely what natural selection is. And yes, we can take a hand in this; virtually all of our food plants and animals, even domesticated pet species and ornamental plants, have been “unnaturally” or “artificially” selected (both of those terms imply a lot of baggage not deserved) to be the species we’re familiar with – in most cases, to our benefit, though there are notable exceptions. Overall, however, the “wild” versions of our food grains were nowhere near as hardy nor produced as much usable product; the “natural” species of livestock were leaner and far less docile, quite inefficient as food sources or even labor elements. We’ve been up to this for a long time, and the beneficial results can only be argued with abject denial (which will still occur anyway…)

So what about humans, as a species? Is it possible, ethical, and effective to consider selective reproduction for ourselves? Ah, such a loaded question! There’s a lot to consider here.

First off, we already do – our choices of spouse (or even just sexual partners) really is self-selection, though we often remain unaware of the extent, or the subtle influences that inherent traits have on the process. So the question is more about how conscious we can/should be about the process, and whether we should have more direct goals than the basic urges – a dividing line between “natural” and “artificial” that’s really hard to define (you see what I mean about baggage?)

Second, we would really need to understand what factors are actually affected by genetic heritage. Marrying a highly intelligent person is unlikely, by itself, to produce a highly intelligent child (unless you have sex) because intelligence is produced by culture and upbringing, not genes to any significant extent. It would be nice to say we humans have moved away from decrepit ideas of other ‘races’ possessing traits of laziness or overeating or whatever, but this hasn’t really been demonstrated too well. So selective breeding isn’t likely to be functional in any way whenever it’s based on false premises and gross misunderstandings.

Despite all that, there are already rudimentary functions of this nature going on, from an effective basis as well. Genetic tests and even family history can give an indication of high risks for problematic children, letting the parents decide whether it’s a good idea to bear a child that is likely to struggle with problems or illnesses, such as cystic fibrosis or Tay-Sachs disease. Sometimes such considerations get bogged down in vapid, misdirected discussions such as “denying a child life” by not getting pregnant, as if there’s a stockpile of aware, pre-mortal lives waiting to be born someplace, or if genetic decisions are some method of trying to second-guess god, whose decisions are far more predictable through genetics than any method the devout have tried.

Given the myriad assumptions and misconceptions tied up in the topic, discussions of this nature become very difficult – either someone feels that the process shouldn’t be tampered with, or that it involves factors that really don’t apply (or both,) so things get bogged down very quickly. One can add in lots of other sidetracks like the fear of mutants or the belief that all scientific research results in terrible consequences – because, apparently, enough people get their knowledge of science from B-movies – and produce lively yet ridiculously pointless arguments.

Speaking of that, what are the ethical views of genetically engineering humans, occasionally referred to as “designer people”? Throw this question out in any gathering to watch the reaction; for fun, change up and insert the word “fetus” in another discussion. Take a stopwatch and see how long before the word “tamper” comes up in response (the watch had best be able to display hundredths of seconds.) A moment’s thought will demonstrate that this is absolutely no different from the breeding we’ve been doing on dogs and roses for centuries, but the idea that humans are in some way a special circumstance repeatedly rears its head; this goes doubly so for fetuses (feti?), though any genetic modifications would take place at the single-cell stage long before cell division, since genes affect development. But our sense of protection over infants, which is admittedly pretty important for survival, kicks in where it really doesn’t apply. People begin trying to draw an arbitrary line of where “life” begins to define where it’s improper to mess about – the same people who take painkillers and antibiotics and undergo laser surgery on their vision and all that jazz. Seriously, if you’re quick on the draw, you can while away many evenings by challenging other peoples’ perspectives. Granted, your group of friends may dwindle a bit…

And I have to add, any discussion of genetics in this manner assumes by the very topic that humans are just as evolved as everything else on earth – no pedestal for us. A lot more fun can be produced if you start challenging someone to define how we, as natural beings on this planet with naturally evolved brains, could possibly do something “unnatural” or “artificial,” any more than a spider that selects a mate.

It’s been asked quite often whether humans have actually stopped evolving; our advances in medicine, living conditions, and general knowledge of hazards has compensated for many of the conditions that killed us off, death being one of those tools of selection. The most prominent contributor to this idea is the burgeoning population of the planet, with the birth (survival) rate overtaking the death rate significantly. If human evolution really has stopped or slowed, even partially, it might make sense that we should take a hand in selectivity ourselves. Yet, this is applying the idea of evolution to a much briefer scale than it really operates. Evolution takes place in populations, which for us now is worldwide (a fun thought we’ll come back to,) over very long periods of time. Our population issues are quite capable of demonstrating that evolution has not stopped for humans, should we reach the point of starving ourselves, and what is likely to happen is that we develop far less desire to reproduce. This will take a long time; parents (genetic lines) that have lots of babies will spread their genes faster than those who have fewer, which is exactly the opposite of what we would want to happen, but in crucial areas with limited resources all of those children may starve (or have developmental issues through poor nutrition, and so on.) But if a prolific couple has just one of their many children live to reach reproductive age, this is exactly the same effect as the couple that desired and raised only one child – the genes that contributed to the urge for many children or one child are on an equal footing and pass along in this circumstance. Plus, there’s the idea that we are not geographically isolated anymore, so a newly-arising “limited children” gene may go anyplace on the planet, decreasing the likelihood of reinforcing itself within a small population; it stands a much greater chance of losing out to a more dominant gene and failing to be carried through to offspring. This makes the process much slower overall.

Yet, the necessary genes to limit populations may already be in effect – it’s easy to believe most parents would be wrecked with seeing their children die off and would tend not to reproduce quite so enthusiastically in situations where survival was highly questionable. Meanwhile, viruses that spread easily in crowded conditions only have to surpass a certain threshold of both immune resistance and host mortality to thwart our medical advantages; a pandemic is only less likely with our knowledge, not impossible. Plus zombies.

So the issue isn’t really that natural selection is no longer working, or even hampered; it’s that we would prefer to avoid the way it actually works, for instance, by replacing infant mortality with voluntary childbirth limits.

Now here’s another problem with conscious selection: few people would select against themselves. We already have traits to promote ourselves in numerous ways – put simply, ‘ego’ is the importance of the organism. Hell, we cannot even dispense with alcohol, tobacco, and handguns throughout our populations, despite the complete pointlessness of them, and I can predict that a large percentage of people reading that statement will formulate countless defenses of any or all of them, mostly based on imagined scenarios and in denial of the real-world evidence that proves the point. Such responses aren’t the product of rational consideration, but the internal prods towards a perceived beneficial outcome; “This gun makes me more competitive than my neighbor, thus I am a better mate.” As a species, we struggle with the objectivity that would be necessary to perform efficient selection. If we examine our recreational activities, it’s plain that we’re infatuated with indulgence rather than functionality (nature photography being a notable exception, but that goes without saying…)

These tendencies towards indulgences, from the “right to raise as many kids as I want” to our eating habits to altering our minds with substances for recreation, are all evolved traits, as is just about everything the defines us as a species. Most (perhaps not all) we possess because, at one time anyway, they were beneficial; the caveat is in there because occasionally a neutral trait comes through, something not directly beneficial but not detrimental enough to be selected out. Yet. Even harmful traits can manage to survive through recessive genes, ones that can pass along largely without effect until the right sexual combination causes them to become active. Overall, though, much of our ‘instinctual’ behavior is bred into us – it’s what we want to do, so conscious selection may have to fight against subconscious directives. As indicated above, this might be a really hard thing to accomplish.

Sidetrack for an interesting thought. If a tendency towards alcoholism is genetic, it may eventually get selected out by the host dying before reproduction, especially through driving, swimming, and extreme-duding while intoxicated. Raising the legal drinking age, however, actively works against this; the chances of producing offspring before the selective fatal event become much higher, and the genes, however detrimental, pass on. What this means is that we could potentially eradicate alcoholism much faster by doing away with age restrictions on drinking ;-)

Leaving beside the attempts at humor that can be quote-mined to show that atheists are immoral savages (quote-mining being such an ethical activity in itself,) we can consider what kind of mindset it would take to actually induce conscious selection. Since there isn’t a significant separation of human populations, such a mindset would have to be worldwide. It would have to incorporate a much better understanding of genetics than average right now, in order to make the slightest progress. It would have to have agreed-upon goals, unfettered by culture and religion and differing conditions among the continents. And it would have to remain important in our minds for a long time – longer than any language has existed on this planet. Basic answer: it ain’t happening. From the standpoint of how we might cope with overpopulation issues, this isn’t heartening, and it’s even less heartening when we examine the significant possibility that we could drive ourselves to extinction with our poor use of resources – nature might demonstrate that a tendency towards self-indulgence is not a survival trait.

It’s not all bleak, however. As noted, we already get bad feelings from infant deaths, and from watching others starve – it’s not that we’re oblivious to our own mortality, it’s simply that we don’t often make the connection. Once made, the cause-and-effect pattern recognition that we possess is potentially enough to override the “make babies” instinct – we’ve already demonstrated that this works by the numerous forms of birth control we have available. And there are other ways of affecting our survival, short of trying to breed a new human. The eradication of polio, in a very short period of time, shows that sometimes we can change our environment, rather than ourselves. Obviously there are limits, but it’s not like we’re trapped by evolution’s rules or powerless to change – we just have to select the changes that are most likely to succeed.

I’m going to depart from this line of thought to approach another, distantly related one. One of the basic factors of speciation, the ‘branching’ of family trees that eventually leads to separate species, is geographic isolation – not the only contributor, but a major one. One population of organisms gets separated from another and they go through unconnected genetic paths; continue this long enough and they diverge far enough genetically to lose the ability to reproduce with each other, and voila, someone has to change their Latin name. As mentioned above, human progress has significantly lessened this likelihood for us anymore, since we can travel across the planet. Granted, we still tend to stay at least on the same continents, but enough mingling takes place that, on an evolutionary scale, there really aren’t isolated populations anymore. I certainly am not Native American, though I live on that continent, and this applies to the majority of the population here. Humans are highly unlikely, given the conditions now, to branch off into two or more species, despite the numerous variants in the hominid line from the last ten million years.

There’s one major exception to this, touched on by a few science-fiction writers over the years: space colonization. It’s hard to imagine a more uncrossable divide than open space, not to mention the likelihood of wildly different environments. I’m not referring here to the ‘Star Trek’ planets with similar atmospheres and gravity, useful for fantasy writing yet ridiculously implausible, but instead to the difference between the micro-ecosystems of encapsulated colonies and the conditions here on Earth. Recycled water and scrubbed air and monitored levels of UV, necessary for a self-sustaining colony or ship, could begin to lead the species off onto a different path.

Yet there’s more than a few things wrong with this as well. The first is, we probably only see space colonies as an option because we have a drive to explore. From a practical standpoint it’s ludicrous, because the conditions of our planet aren’t duplicated too much anywhere else (as in, “at all,”) and the efforts to create conditions that are hospitable, especially for either long distance colony ships or creating a sizable colony on the moon, far exceed what it would take to simply stabilize our populations and resource usage here on Earth.

Then there’s the idea that we would maintain a colony elsewhere long enough to see speciation take place. Bear in mind that lions and tigers are distinctly different species, to all appearances, yet can interbreed to produce offspring – this is an example of how difficult it is to define separate species, but more to the point, their geographic separation hasn’t gone on long enough. Splitting of the Homo sapiens line would take thousands of years of isolation. There is, to be blunt, a far greater chance that either population would be wiped out by a cataclysmic event than both developing to the point of species divergence. Right now it’s still debatable whether we’ll be able to solve the problem of a major asteroid strike before it actually occurs (I’m quite confident in saying, if it occurs within the next decade, the answer is “no” – we’re toast, pure and simple.) There are even indications that our current existence owes much to no major extinction event having occurred for a while – a piece of luck providing a false sense of security.

Is there a conclusion to all this? Not at all – just food for thought. The best I can offer is, better to think of it now (and in a rational manner) than when it’s too late to be of use.

TL;DR

Those letters are internet shorthand, not for, “Transgender lifestyles; Dominican Republic” as you might expect, but for, “Too long; didn’t read.” It’s the battle cry of the short-attention span, the post comment meant to be critical, but instead illustrating the missing depth of the commenter. “Reading is hard,” it says, “You’re expecting too much of me!”

A recent article in Slate talks about this at length, albeit with no small amount of self-aware irony. Chartbeat is a service that analyzes internet-traffic, and they produced several graphs that show just what kind of behavior people had when visiting sites. Long story short: the graphs show a lot of immediately lost interest, and a lot of people who never read to the end of an article. Frequently, the response to such info is that web content should be short, and from the standpoint of someone who frequently crosses the 2,000 word mark, I should be scared.

I’m not; I know a little more about data analysis than that, not to mention perspective. Think of it in terms of TV; how often does anyone turn it on, select one channel immediately, and watch the program until the end? Even if we go for the archaic idea of reading books, how many people do you know that start and finish a book in one sitting? Does this tell us that humans overall are unfocused and scatterbrained? Or simply that we have unrealistic expectations of attention-span and information absorption, not to mention priorities such as eating and stopping the kids from shellacking the cat? (No, that’s not internet slang for anything. I don’t think.)

There are some significantly wrong assumptions to be found as well. As writer Farhad Manjoo says:

The more I type, the more of you tune out. And it’s not just me. It’s not just Slate. It’s everywhere online. When people land on a story, they very rarely make it all the way down the page.

Manjoo has fallen for the average fallacy, as if there is anyone, much less everyone, who can be considered average. “You” are tuning out, and “people” rarely make it to the end of a page. Utter unmitigated horseshit. Everyone is different, and no purpose is served by lumping every visitor to a site into one single amorphous entity. You have your own interests, as do I, and they don’t agree on every point, so simply taking an average of the two of us on any given page, we might make it 50% through – that doesn’t mean we both gave up halfway. I stayed to the end, and you flittered off like you usually do…

One must consider that content is not often structured for long-term visits. Let’s look at Slate’s own page featuring the article itself, color-coded to make it more eye-catching to separate the content according to focus. This is what the page initially looks like in my native screen resolution (which may not be typical anymore,) emsmallened to fit the blog format:
SlateWindow
The stuff highlighted in blue is direct article content – what anyone has come to see, based on any outside link. Green denotes the illustration, connected but not really content – a lead image can be a teaser or visual aid to the content, but most often (like here) it’s simply intended as eye-candy to help promote interest. Red is completely unrelated junk, stuff that leads the viewer away from the content. All of this is, naturally, without scrolling, one of the factors mentioned in the surveys – a certain percentage of people leave without ever getting beyond the info seen here. So that’s less than 10% solid content, just the title for shit’s sake, and a photo competing with all the crap on the side. This might be better if a compelling photo was chosen, instead of this lame stock agency placeholder to fulfill the editorial idea that there must be a photo. If you found the article unable to hold your attention, this is no surprise, because the page is obviously designed to to emphasize everything but…

Worse is that Manjoo really hasn’t written a profound article – basically, the title is supported and little else. Sites that base their content on a minimum number of articles (especially in certain categories) and some misperceived need to produce new content end up with a percentage of uninteresting dross. Manjoo injected a little humor within, but never got to an insight or hook, despite the clear possibilities of the topic. To be fair, Slate’s editors had some hand in this, and for a site this size that’s not insignificant – Manjoo may not even write like this on his own. Regardless, it means too many articles that don’t go anywhere – which means that anyone staying until the end is more wasting time than demonstrating their exemplary focus.

No site is going to grab and hold everyone’s attention, and this says nothing useful in the least about either content or human tendencies – if you’re like me, at times you’re interested in one kind of content, but other times you couldn’t care less. You might, hard as this may be to believe, treat most web content as passing time, falling below many other of life’s pursuits in importance, which means you’re willing to interrupt perusing a website for just about anything else. And you may be loathe to admit it, but you might just not give the slightest damn about celebrity gossip, despite the bare fact that we’re supposed to enraptured by such as a species. You’re wrecking the curve by doing so, and you bear this on your own conscience…

That hints at an assumption made too often, the idea of selective sampling. The “TL;DR” commenter might stick in our head, partially because it’s such a shallow response to any article, but also because it’s an exception – which belies the statistical significance. We might also see, perhaps much more frequently, the long measured responses, the political diatribes, and the related personal recollections, but these aren’t half as much fun to talk about, even when they overwhelm the short-attention-span nitwits by a factor of five or more. Anyone can opine that YouTube comments are a sign of de-evolution in our species, but this must be weighed against sites where the discussions are lengthy, reasoned, and civil.

As for me? I… write what I want to, and feature what I want to – it is a blog, after all, which translates as thinly veiled narcissism. If anyone else likes it, great! – kindred spirits and all that. I may not hold the attention of anyone who watches reality shows, and I would be proud of this. The result might be low hits or high ‘bounces’ or whatever, but the point was never to be one of the crowd, vapidly (and vainly) aiming for some average ideal – variety is generally a nice thing, no? Anyone can chase statistics all they want, especially if they believe web content is supposed to make money, and true, a lot of content could be vastly improved. But doing so with a solid perspective is probably much better than misinterpreting survey results to believe that humans are turning into twitchy neurotics or something.

Damn. Failed to bring it in under a thousand words…

A peek at the process

HappyWet
We had gone through a longish period with no rain, and the azalea bushes were started to suffer from it. So I pulled out the hose and gave them a good soaking, with a heavy stream directed at the base to reach the roots, then a light misting over the top to make the insects happy. Almost immediately, the one brown resident mantis scampered excitedly into the water. I really can’t interpret this any other way; it was not trying to escape the soaking, nor did it appear to have been ‘flushed out,’ and had not been visible above the leaves before I started. It simply appeared right in the midst of the mist and came fully out into the open. Of course, I had to get a pic that attempted to communicate this behavior.

Now, it comes as no surprise, I imagine, that blogs are self-edited, which means that not only do you get to see the sentence structure and subject matter that I consider worthwhile (for better or worse,) but also the images that I feel illustrate them best. Until now. I took several images of my friend enjoying the soaking, and decided on the one above. So here are the other choices, all full frame, followed by the reasons why I ruled them out.

MantisEdit1
Not quite. While it showed the body color and the moisture, and even the sorry state of the formerly-vibrant blooms, the lighting is uneven and the perspective too impersonal. While I might have been misinterpreting the mantis as enjoying the water, this doesn’t show the behavior anyway; more the opposite.

MantisEdit2
More of a portrait than an illustration of behavior, and the wetness of the entire bush doesn’t come through too well.

MantisEdit3
Same thing, even more so. The droplet on the antenna is eye-catching, but so is the reflection from the drop on the abdomen, unfocused as it is, and the forelegs almost look like they belong to something else. Plus that stamen to the right is distractingly sharp, though that could have been cropped out easily…

MantisEdit5
Now, I really like this image, with the focus on the forelegs and the drops, but it’s admittedly a rather menacing impression. And again, it’s a portrait, not a display of the behavior I was describing. Hopefully, you agree that the first was the one to use for the topic. There are times when I’ve gone out to reshoot something specifically to illustrate a post better, and this says nothing of the effort put into the images for book reviews (that one is indeed ‘shopped, since I couldn’t locate a goat when I needed one, so I used an archive goat pic and photographed the book in the position and lighting to match.)

There are a couple of messages here. The first is, take enough images to provide a choice, a selection of conditions, behaviors, angles, and so on. Sometimes, one of them will stand out as expressing an idea much better than the others. Secondly, you’ll have plenty of flexibility when it comes to end usage, which may not be what you originally had in mind when getting the shots. In cases where there’s a different editor than yourself, you have to meet with their expectations.

Also worth considering, especially with macro work and its tight margins, is that focus might not be bang on, or minor movement may have destroyed sharpness – something that the preview image in the LCD on the camera will not tell you. Multiple shots are greater insurance that you have something usable. And when using flash for lighting, varying angles usually give differing results with reflections and shadows, something not at all visible in the viewfinder.

Obviously this is where digital shines, but even when shooting film, multiple images are a good idea – it would be nice to think that every shot is sacred and shouldn’t be wasted, but quite unrealistic. If you get one image that significantly surpasses the others, especially if it makes the sale, then throwing away a few slides isn’t any great loss.

StillLynxAfter dousing the bush, naturally, the rain started later in the evening – yes, the weather report had indicated the possibility, but this is North Carolina, where that’s perhaps even more questionable than other areas of the country. I’ve learned my lesson before by almost killing plants in the garden, waiting for the promised rains that never came, and now water as needed regardless of the threats. The mantises appear quite happy with the rain, sitting well out into the open, and so is another resident. Just yesterday (as I type this draft; probably several days ago now that this post is published,) I was thinking that I hadn’t seen the tiny green lynx spider after that first day, and figured that it had fallen prey to the mantises. Just to prove me wrong, it reappeared on the same bush, still only centimeters away from the (now much bigger) mantids. Somehow it appears to be coping with less aplomb than my model above, though that’s just an impression; both species are probably equally capable of dealing with rain. But it does seem that the mantises are finding more to eat.
