Today marks the 40th anniversary of a remarkable accomplishment for us, as a species: Walking on the surface of another body in our solar system. Despite the politics, despite the nationalistic fervor, despite the questionable use to us at a time when we had lots of more important things to think about on our own planet, despite even the fact that Armstrong flubbed the line (I’m sorry, really, but he did), this one event will stand forever as a milestone for all humankind.
I was three years old – I missed the awe and the excitement by a mere smidgen of attention-span and understanding. And I’m sorry to have missed it. But I also grew up on the space program, collected books and photos and posters, built models, and watched the later Apollos and soon afterward, the Skylab missions. Even at a young age, I could absorb some of the amazement at how much we were accomplishing from an engineering standpoint. As I grew older, this has only grown – the space program was a peak in our scientific problem-solving capability that I feel safe in saying we haven’t surpassed since. We flirted, in so many ways, with disaster, and regretfully witnessed it a few times. Not just Apollo 1, Challenger, and Columbia, but Bondarenko’s pressure test fire and Soyuz 1. There are those that feel that any lives lost represent both too much risk, and a failure of the programs. I can’t agree – some things are worth the risk, and every one of those who lost their lives in these endeavors knew just what the stakes were. Hell, give me the choice of a rocket exploding underneath me on the way into space, or dying in bed of cancer, and I’ll go with the rocket every time.
What’s funny is that, now that I think about it, my perspectives on this as I grew up seem to parallel our country’s perspectives on the space program. Early on, it was fascination, awe, wonder, and a pretty powerful desire to do that myself someday. Then it began to get more detailed as we got past the excitement of walking on the moon and began seeing what else we could accomplish with Skylab, living in space and working in shirt sleeves. Still very cool, but not “exploring” and “new frontiers” so much. Then the promise of the space shuttle, going from initial sketches to the idea that this really was going to fly, soon marred by the budget and design issues. The various tests of the shuttle would perhaps have been more fascinating if they didn’t seem to be repeats of the Mercury and Gemini tests – now it was almost beginning to be routine. And finally, we started seeing the shuttle from a cost-effective viewpoint, all grown up now and trying to balance the budget. It’s a shame, really, because the space program gave us so much wonder and pride, and the energy to do just about anything, and now we seem bound up by responsibility.
In direct contrast to this public attitude, it seems to me, is what we have added to our body of knowledge during that same time. I grew up with books that speculated on where the moon came from and where the age of the universe was “between 10 and 20 billion years.” And I watched all of this change, and not gradually either. Black holes, speculative when I was even in high school, are now virtually proven, and we have mapped the variations in the Cosmic Microwave Background, the dissipating heat from the origin known most unfortunately as the Big Bang (13.7 billion years ago, now). Astronomical knowledge has grown, well, astronomically, and we add to this constantly. We have a satellite in orbit around another planet that took a photograph of a planetary probe as it descended by parachute! Not impressed? We have hundreds of satellites in orbit around our own planet, and to the best of my knowledge we have no photos of any spacecraft entering our atmosphere.
Take a look at that photo above. Right in the center, there’s a dark lunar Mare, and to the immediate right, there’s a brighter portion about like a chicken head eating a speck. From this perspective, just below and to the left of that speck is where it all began. That’s Apollo 11’s landing site. Yuri Gagarin was a hero himself, don’t get me wrong, and so were all of the other spacefarers who contributed to every country’s program. But right there, 40 years ago, we knew what we could accomplish. We walked on the moon.
If you lived through it, or even close, be sure to take aside someone much younger and try to convey some sense of this spirit. We still need it.

…or perhaps, with certain people doing so.
No, I’m not going to attack what other people choose to write about or how they do it. This is a blog – it’s supposed to be about me! ;-). What I’m starting to find now is that I don’t like writing something as a “stream of consciousness” or introducing an idea. I’m a personality type (I think, anyway) that likes to present something as a complete work and orderly concept, rather than as an initial thought. So, while I have ideas for posts that occur to me several times a week, I don’t like the idea of just hurling them out there. I much rather prefer a finished form.
There’s perhaps something good about this, in that I’m not writing something that I’m more likely to look at later and cringe (note that I said “likely”). I’m never really sure of how “public” such a thing is, at least at this stage – I might have four readers right now, so that counts as less public than many things I do for my job. But, perhaps, that may not always be the case, and will I feel comfortable with what I’ve written before?
The problem with “finished form” is that, too often, there is no such thing for me. Some ideas that I have that I consider compelling just seem to lead further onwards. Do I pick a stopping point? Or should I try to flesh it out better and complete the path? If I choose the latter, I find that I’m now trying to write a complete magazine article, self-edited, with fact-checking and sources. While not a bad pursuit, that kind of defeats the purpose.
I’m also sensitive about writing something that I think is pretty cool, that’s actually been examined in depth by someone else – I feel like that’s just showcasing my ignorance (“Hey! What if we sliced bread ahead of time?!?!”). There’s a trap to this way of thinking, in that there are very few subjects that are unique. It’s the same kind of trap that I fall into with photography, and that I have actually argued against – the artist that insists on being unique has got a huge challenge ahead of them, and may only achieve “being weird.”
And finally, there’s this last little concern: giving away an idea. I’m writing stuff for eventual publication right now, or so is the goal, and there’s a certain amount of competition to that. I have to be sure in my mind that I’m not going to want to develop some post idea further and do a full-blown article on it. First of all, having the same thing in short form on a blog seems to indicate to an editor that I have too few ideas (maybe? I could be imagining this), but it also could mean that someone who’s a faster writer runs with the idea before I do. This is probably the least of the worries, but it’s a factor nonetheless.
So, my posts are less frequent than many – but that makes them better quality, right? Yeah, sure, that’s it…
Anyway, feel free to chime in with your own thoughts.

Okay, this is kind of a frustration. It’s also kind of an accomplishment. What you’re seeing above is a northern black racer (Coluber constrictor constrictor) that has just captured an eastern garter snake (Thamnophis sirtalis sirtalis).
I was cutting up a trail through the woods while at work when I heard a rustle practically at my feet. One of the things I teach in my classes and seminars is about finding photos with your ears – sounds can lead you to photographic subjects quite frequently. In this case, it led to what I initially took to be a black rat snake alongside the trail, roughly a meter long. His head was hidden from view, and curiously, after the initial sharp rustle, he was motionless. I started edging around to get a better view of his head, and spotted the body of the hapless garter snake, still writhing. I wasted no time in scampering up to the parking lot and snagging my camera from the car, as well as my cell phone, which I used to summon a couple of co-workers up to see this. While I waited, I stayed still and unobtrusive so as not to spook the snake under cover. The snake had made it clear it knew I was around as I returned with the camera, because it gave a vigorous vibration of the tail.
[A quick side note: Many snake species, not just rattlesnakes, vibrate their tail as a warning. Rattlesnakes just have a handy noisemaker. But other species can produce much the same noise as the tail drums against dry leaves, and it’s an impressive sound, let me tell you.]
Once the others had their opportunity to see it, I maneuvered into the brush a bit to get a better view of the head, and eventually secured a nice keyhole in the brush that allowed me to see the dramatic scene above. The accomplishment part of this was even seeing such behavior, much less getting a reasonably clear shot of it. Snakes feeding in the wild are incredibly hard to find. They know they are quite vulnerable during and immediately after a capture, and usually, to even effect a capture in the first place, they have to be motionless until prey comes within reach. We humans, with our noisy blundering way of moving about (even me), tend to let every species within earshot know we’re about. Now, snakes don’t have ears, but they can feel vibrations through the ground, so while we’re slightly more subtle to them, it’s not by a huge margin.
The frustration part of this was twofold. The first is that it was difficult to get any kind of view at all of the drama, as it were. Even cropped tight as this is, you can see in the photo the out-of-focus brush to either side of the subject (the tan haze to the right side is a branch too close to the camera to be in any kind of focus, but still illuminated by the camera flash), and this was as good as I was going to get. Trying to get closer would either have spooked the snake into deeper cover or caused it to release its prey. And as I said, it was well aware that I was around, and not happy about it. Thus the second part of the frustration: while I would have loved to photograph the remainder of the story, there was no way it was going to happen. The snake would undoubtedly have moved into deep cover to finish the meal.
As I thought about this afterwards, I realized I might have even been a factor in this tableau. Considering that I witnessed the death throes of the garter once I spotted it, this meant that the racer’s strike had not occurred long before, and was perhaps even the rustle sound itself. Coupled with their proximity to the trail, my sudden presence might have spurred the garter into the racer’s range, or maybe even have fatally broken its attention from a faceoff between the two.
Now, here are two things of interest from this particular shot. The first is that, the difference in the size of the two snakes is not a big one (though it’s hard to determine from just this image). This is a significant meal for the racer, and would last it at least a month from my estimate.
The second is a subtle one that adds a lot to the scene without, I suspect, most people realizing it. Snakes don’t have eyelids, and don’t change expression in any way. Both species have a natural ridge above the eyes that we tend to see as an eyebrow, and gives them a slightly mean frown to our eyes. In this case, the angle of the garter’s head hides the ridge and gives it a wide-eyed look, while the angle of the racer’s exaggerates the ridge and makes it look nasty. Given the poses, we automatically expect such expressions, but there’s no expression there for either of them. What we imagine we see, however, fits with the brutality we assign to this action. It’s important to remember that we can’t assign human traits to this, and what we’re seeing is simply normal behavior in a world we pay too little attention to. There’s no animosity, no emotion – the racer was hungry, and the garter not fast enough. So it goes.

This is a post I’ve put off for a while (considering the trip was in April) for a number of reasons, none of them particularly good. But I’m not a fan of personal whining on a blog, and intended this for more items of interest rather than minutiae of life, so I’m skipping a lot of stuff I just typed ;-)
The trip, to me, was a bit frustrating in that I didn’t get to do some of the things I had planned (like snorkeling) and got no photos that I felt knocked me over, something that I hold as a personal goal with any trip. This isn’t to say I got no photos I liked – I added plenty to my stock! But none of them made me really excited to display. I tend to look at this as my own (failed) perspective, though, because some of the places The Girlfriend and I visited, like Venice Rookery, were fascinating. That’s called a teaser – it continues below the jump ;-)

In trying to upgrade and backup my previous installation of blog software, I somehow seemed to have lost the system. Not sure yet if the posts have vanished entirely (I made my own separate backups, but they may require the database to be coherent), so if anyone’s reading, be patient. I decided to dump B2Evolution’s software and go with WordPress, so I have to reformat the whole thing.

It is finally looking like a trip to Florida is going to take place in April. Ever since moving from there a few years ago, I’ve been yearning to return, if only for the opportunities that it provides to nature photography. And, due to crummy finances and difficulties with work schedules, it hasn’t had the chance to happen until now.
This is far from being an ideal time, and in fact, it falls between two target periods. In February (I hate that word, completely unintuitive to type) and March, the birds are nesting and raising their broods, and Florida attracts a multitude of species. And high summer, despite how most people feel about it, is useful for two reasons: it will give my girlfriend a taste of the worst that Florida has to offer, to see if she can stand to move down there someday; and it produces bioluminescence in the bay waters.
When I first discovered this on my own a few years back, I found it absolutely fascinating, and that hasn’t changed. Certain microorganisms in the Dinoflagellate family produce a brief blue-green flash when agitated past a certain level, and large collections of them will produce a dim glow in turbulent water. Toss a rock in, and you’ll produce a shockwave that delineates the ripples for less than a second – in good conditions, you might actually see the secondary effect from the little fountain that plumes from the center of impact and falls back down. Put your hand in and thrash it around, and you’ll produce a brief cloud of color that wisps away quickly. Chasing this effect in the nearby waters of the Indian River Lagoon led to two rather interesting experiences, which I’m relating out of order just for the drama.

Yeah, I expect this to be an ongoing series… ;-)
I can’t say I really know how easy other nature photographers have it, though I imagine they face many of the same frustrations I do. I need to say here that I’ve always held a full-time job not related to photography, because, bluntly, I need to pay bills! So my nature photography takes place on the side, when I can arrange the time to do it. It doesn’t help that where I live presently is not as rich in subjects as other places I’ve lived (like Florida), so making a decent weekend of shooting often requires traveling somewhere else.
(Of course, one of the things I emphasize in my nature photography talk is finding subjects anywhere you are, so I’m contradicting myself here. The truth is, you really can find subjects anywhere, but some places are much easier than others).
 So, what about my buddy to the right, here? What’s his story?
This is a Pileated Woodpecker, the biggest woodpecker species in North America – unless, of course, it turns out the Ivory-billed Woodpecker is still extant, something that’s in debate right now. These guys are a bit more common though, but still fun to watch. This particular one was taken practically right outside the door where I work. And that opening in front of him isn’t for food – he’s making a nest.
I don’t get opportunities like this too often. It’s one thing to stalk through the woods at a key time in the year, listening for bird calls, until you locate a nest in construction, then find a prime location, set up a blind, and spend a lot of time staking out the nest so you can catch nice, detailed shots of behavior and plumage and, most especially, the young being fed and venturing out for the first time. These kinds of shots can take a lot of effort.
However, it’s another thing to have a woodpecker, who doesn’t mind relatively close approaches, creating a nest right alongside where you have to be every day anyway. And since I work for a wildlife organization, finding the excuse to walk outside routinely isn’t that hard. When I got this pic (admittedly a tad softer than I like), I was psyched. I was looking forward to a whole series of shots that I’ve never been able to devote the time to before.
Alas, it was not to be. The key part of all this was this male finding a mate to go along with the nest, which never happened. Part of this was probably due to another male in overlapping territory, which resulted in a few disputes. Another part may have been that I never once spotted a female in the area. Eventually, however, the nest was abandoned unfinished, and I only saw this male on occasion after that.
That’s kind of the way it goes. Nature photographers are beholden to how the chips fall (Heh! I’m a wag!), and I think a key part of it all is recognizing that you just have to wait for the right opportunities. It would have been nice to have an active nest 50 feet from my office door, but that’s a lot to expect. And if it’s too easy, the pics don’t have the same cachet ;-)

Some years back, when I had way too much time on my hands, I was active on several newsgroups. Among these were three devoted to UFOs and paranormal activity. I had grown up in the UFO subculture, believed a lot of it (along with Bigfoot, Nessie, and much of Chariots of the Gods?), but with adulthood and the input of various sources I had found many logical difficulties with all of them. My presence on the newsgroups at that time was, as now, from a critical-thinking standpoint, and because I was exercising my photographic knowledge with evaluating the evidence photos.
With such subjects, there are two distinct sides, which I’ll just call Believers and Skeptics for now. These sides, while not necessarily distinct for everyone, nonetheless led to something akin to sports rivalry, and no small amount of pointless sniping back and forth.
Which leads to this. I wrote the list below in direct response to a similar post against skeptics. Yes, it’s intended to be an exceedingly broad generalization, and more than a little tongue-in-cheek. But it’s also wry commentary on the types of arguments that tend to come up in such discussions.

So, I didn’t go out to shoot anything new to kick off the International Year of Astronomy like I should’ve, when we had nice clear skies (but cold, of course). So instead, I’ll post a curious photo and ask for comments.
The pic above was taken in 2007, my best guess is August 13th or 14th, round about midnight EDT. I had set up my EOS 3 with the intervalometer to do a multiple exposure of the night sky. Unfortunately, since this was just an experiment, I didn’t write anything down, so the specs I’m about to provide are in question, and if you have reason not to believe them, then go with your instincts.
Anyway, I believe I ran a series of exposures of 8 or 10 seconds each, 45 seconds apart. I was aimed nearly straight up, and shooting with my 24-135mm lens at, most likely, 24mm (since the zoom would have crept down to that setting anyway with being aimed upwards), which would give this frame a (roughly) 72 degree field of view along the long side. There’s a chance I used the 105mm macro (19 degrees), but doubtful – I think I was using that on another body at the same time. The film is Fuji Provia 100F slide film, because, hey, nothing else brings out the star colors half as well. My position was roughly Lat 36.020° N, Lon 79.131° W.
While am I going into all this? Because, right dead center of the frame, is something I don’t think should be there. Look for the blue dot that’s a little brighter, and extended off the tip of, a trail in the middle of the frame. You can click on the pic above to see the larger version, and I can provide a full-frame scan upon request of anyone who really wants to play around.
No, it’s not an extension of the trail it’s near, with the separation occurring because of clouds – there were none that night. No, it’s not a plane or satellite, since both would have left trails at that exposure length. Same goes for a meteor (and yes, this was during the Perseids storm), unless it came right straight down towards the camera.
So, any ideas? I toyed with the idea of it being a rare visible Gamma Ray Burst, but there’s no record of one occurring during that timeframe. And nothing else has come to mind.
Now, I have no idea what constellation or area of the sky this is in – I honestly do not recall where I was aiming, and perusing sky charts for that time has not yielded any matches yet. Oh, yeah, I should probably mention that I did a Photoshop trick on another version, filtering out all but the end point of each trail to produce a proper starfield. If you download that pic, please keep in mind that I have no idea when that stray dot occurred during the series of exposures, so its position could be anywhere along a diagonal line stretching down and to the right of where it’s marked. In other words, I choose one out of 21 different positions to plot the individual stars, but do not know when the stray dot appeared during those 21 exposures, so don’t consider it accurate in relation to the other stars.
It’s even possible it’s a booger in the film emulsion, but it seems like a stretch to have one that’s the same size, shape, and just a little brighter than the objects in the rest of the frame.
Let me know what you think!
[The following portion added on June 13, 2009]
I stumbled on another possibility that I’m favoring right now: I caught a geostationary satellite. A long exposure posted on, I think, the Earth Science Picture of the Day site (whose archives are unavailable as I type this) showed several points of light among the streaks of an extremely long star exposure, identified as geostationary satellites. They would in the same area of sky no matter what the time or season, hence the name. Internally, I argued that the lateness of the hour when I took the photo would have precluded any satellites being illuminated by the sun, but geosats are way the hell out there, intended to link as much of the globe as possible, so they stand a good chance of being constantly illuminated. Their distance would also make them faint, but my photo is, essentially, 21 exposures, and for something stationary that would mean they’d all pile atop one another to add to the exposure of that point.
Anyone who can shed some light on this (oh my, I’m such a card) is welcome to chime in.

A few days back, Rev. BigDumbChimp (gotta love that name) linked to an article on another blog concerning the origins of christmas. All well and good, and most of it I’d heard before. I didn’t follow the sources that were linked, but I’m pretty sure the Coca Cola bit is spurious, so I have reason to wonder about the other content. However, the overall provenance of the holiday is supported through numerous sources, and it’s far from the story we’re usually fed. Yes, it was clearly co-opted from quite a few other observances and traditions that existed previously, and no, it can not by any stretch be considered the day of jesus’ birth.
While I’m not religious and see no reason to support any claims of such, I still feel compelled to say, “So what?” When it comes right down to it, we can call into question every particular day we celebrate a holiday (July 4, for example), and the number of times our calendar has bounced around and been rewritten makes everything older than a few hundred years highly suspect. It’s not the accuracy of the day that we respond to, but the sentiment behind it.
And that’s where I part company drastically with Lawrence Kelemen, the author of the piece. He says:
Christmas has always been a holiday celebrated carelessly. For millennia, pagans, Christians, and even Jews have been swept away in the season’s festivities, and very few people ever pause to consider the celebration’s intrinsic meaning, history, or origins.
• Christmas celebrates the birth of the Christian god who came to rescue mankind from the “curse of the Torah.” It is a 24-hour declaration that Judaism is no longer valid.
• Christmas is a lie. There is no Christian church with a tradition that Jesus was really born on December 25th.
• December 25 is a day on which Jews have been shamed, tortured, and murdered.
• Many of the most popular Christmas customs – including Christmas trees, mistletoe, Christmas presents, and Santa Claus – are modern incarnations of the most depraved pagan rituals ever practiced on earth.
In other words, shame on us all for celebrating the holiday with Hot Wheels in our stockings.
There are three things I take exception to:
One, If you really want to keep the fires stoked over the “War on christmas,” there’s probably no better way to do it. The whole “war” thing has been this asinine crisschin whinefest because someone dares to recognize that not everyone in the world follows their religion, and yet we still want to send people holiday wishes anyway. I always thought “Happy holidays!” was a measure of respect for everyone – peace on earth, goodwill towards men, and stuff like that? I guess I’d be a better person if I was more selfish and insular about my beliefs – at least that seems to be the message. But Kelemen’s article is just the kind of ammo the martyr crowd needs to keep the “War on christmas” frothing going. And (as I’ll get to in a minute), for no good reason.
Two, I’m afraid I’m disinclined to hold anyone responsible for the origins of a holiday that they know nothing about. “Hi, little girl, did you know your letter to Santa asking for a toy pony was really a celebration of persecution and genocide? You should be ashamed of yourself!” No, sorry, that’s a ridiculous argument worthy of small minds, and I’m inclined to say it’s hypocritical, in that it tries to produce a prejudice where none exists.
And finally, the heart of the matter. Yes, it may well be true that the origins of the holiday were once bathed in reprehensible practices. Go far enough back, and be selective enough about virtually any tradition, and I’m sure you can find something unsavory. There’s a distinct and valid point that’s missed with all of this, though, and it is: We don’t do that anymore. We have risen above it. We, as a species, have recognized that many, many things in our past were immoral, unethical, and generally not conducive to good relations with one another, and we stopped doing them. We still have a ways to go, in many aspects of our cultures throughout the world, but that doesn’t negate what we’ve already accomplished. And more importantly, we take a step backwards when we choose to target some past behavior and try to relate it to our current culture – it is creating a bias, an opposing side, an enemy, that does not belong. That’s not progress.
We celebrate christmas now with family get-togethers, good food, and gift-giving – an overall atmosphere of friendliness, generosity, and bonhomie. That we’ve produced this from past practices of bigotry and persecution is something we should actually be proud of – not that they occurred in the first place, but that we have abandoned them to focus on something much more positive. We should not be held accountable to our past – just our present. Make it a good one.
Happy holidays, everyone.
