Hey, Vernal!

small frame of pond with tadpoles and minnows
If I’d been more on top of things, I could have posted this the day I took it, which was Saturday, and thus only been a day later than the equinox and slightly more, I dunno, appropriate? Timely? Whatever, this is a nice illustration of spring, better than I originally believed, even. I think it’s fairly obvious how narrow a field of view this is, capturing a tiny section of a shallow pond, and I was focusing on the minnows over the leaf. However, I count eleven separate critters or portions thereof present in the frame. If you get more than that, let me know, and I’ll give you a prize of some kind once our independent judges have confirmed the count.

pond slider in near-silhouetteAw, what the hell, here’s another, a pond slider showing off those fabulous nails. I did a tweak in the curves function in Photoshop to bring out the stripes on the head and hind a little better, rendering it slightly less of a silhouette. This is a tighter crop than the original, and it’s interesting the difference it can make – there were no more reeds visible in the wider version, but additional open water in the lower corners, so this crop makes it seem more as if I was spotting the turtle through a gap in a thicket of weeds than the original does. I think our minds, knowing how plants grow, automatically fill in the lower sections outside of the frame with the reeds that must be there. And until I saw the effect for myself, I never would have imagined it working that way, so playing around with exactly how and where you crop an image might bring out a different perspective and impression. Experiment freely.

Equinox color

pussywillow blooms against blue sky
Yes, of course I had to post today, but I also had to post a few images from the other day, since today is grey and rainy. So most of what you’ll see here is from Tuesday’s trip over to a botanical garden.

lavender and yellow pansies, I thinkYou don’t need me to tell you this if you spend any time online at all, because plenty of other sites just love throwing out trivia of this nature, but it’s the equinox today, the day when daylight and nightdark hours are the same length, and this occurs at 6:45 PM. Wait, what? The sunlit and sunbarren hours are the same, only at 6:45? What form of sorcery is this? But no, it simply depends on what definition of equinox you’re using. The seasonal changes and the variable daylight hours are both due to the tilt of the Earth’s axis, in relation to its orbital plane around the sun, and over the course of a year this makes the sun appear to reach higher or lower into the sky at celestial noon (which is rarely 12 o’clock, and why the hell are we still using such an arcane word as, “o’clock?”) Today, the Earth’s orbit hits the point where the sun appears directly overhead at the equator, which serves to make those bright and dark hours match up, but the precise point when it is nice and aligned is 22:45 UTC, or ‘Greenwich’ time, which is 6:45 PM here on the east coast in Daylight Saving Time. Are you getting the impression of how goofy our system of time is? Yeah, I’m one of those who’s firmly in support of the entire world switching to UTC and having done with it. Many people think this would be confusing – “That would mean the sun rises at 11 AM!” – but so what? They’re just numbers, and the sun rises at a different time every day anyway. If you take your lunch break at 5 PM according to the clock, what difference does it make if it’s still midday to you?

pond sliders getting some sun
Many also consider this the first day of spring, which is also nonsense – call it whatever you want, or perhaps something appropriate to the present weather. It may look like spring around here, but further north it’s got some time to go yet, and down south there might seem to be no winter at all anyway. What it is, however, is now warm enough that the birds are nesting and the reptiles are stirring, as shown by these sliders basking on the only log they could find in the pond. The exact species is debatable – yellow-bellied sliders (Trachemys scripta scripta) are native to this area, but their close cousin the red-eared slider (Trachemys scripta elegans) probably don’t naturally reach this far north. However, they are/were popular as pets, which is often enough to introduce them to a non-native habitat, and they can easily live in the same conditions and even interbreed with their yellow-bellied cousins. The red ear-mark can easily be seen on two of these at least, so there might be a mix of species in this image.

purple and white crocus, maybe?Now, admittedly it’s cheating a little to go to a botanical garden and post about signs of spring, since so many of the flowers are tended in greenhouses and planted outside as they approach their peak display, but it’s true enough that many of these would be appearing now anyway. I avoided the wider shots that would show the retaining walls, planters, and other manmade stuff, plus I like going in for close details anyway. Only a small percentage of the myriad flower species had identifying plaques, so I can’t provide definitive ID, but I suspect these are crocuses. Whatever, they present a great mix of colors.

close slider portrait
Another slider, one that wasn’t being cooperative because it was too cooperative. You see, I spotted this specimen basking, and decided to do some work with a student on approaches and stalking, practicing how to get closer without spooking the wildlife away. Only, this turtle was so mellow that it never moved at all, even with several examples of behavior that would send the average terrapin scrambling for deep water. So it wasn’t very good practice.

turtle reflection portrait in pond's surfaceBut since it was going to sit there like a bump on a log (or rock, in this case,) I did my own extreme closeups, including a reflection portrait. I was admittedly using a long lens for this and not the macro, so I wasn’t anywhere near as close as these imply, but I was still much closer than I had any right to be. You have to appreciate the irony, though, of encountering hundreds of animals over the years which spooked long before I could ever get a decent image, and then wanting to demonstrate how tricky it is to approach many species and finding one that couldn’t be assed to move at all…

brillaint purple flowers
Okay, there’s something curious going on here. I’m probably not alone in considering these a brilliant purple in color, but let’s stop and take a close look. The petals actually run the spectrum from white down to a deep purple only at the very tips, and I suspect it’s this gradient that makes us believe the colors are so rich (helped, perhaps, but the contrasting orange sex organs in the center, and certainly by the surrounding green.) The drying blossom to the right is a deeper color, but not as vibrant in appearance – it’s not the color that’s cluing us in. Maybe it’s just me…

hybrid plum blossoms Prunus cerasifera 'Atropurpurea' x Prunus mumeThis one I can identify, because the ID plaque was present, and if I’m interpreting it correctly it’s a crossbred plum, Prunus cerasifera ‘Atropurpurea’ x Prunus mume – say that in Hogwarts and something bad will happen (like that’s unusual.) Almost immediately after getting this image, a group of students passing by excitedly directed my attention to the snake at my feet, and on glancing down I found an unimposing brown snake slithering determinedly across my sandal. I think they expected me to react in shock or something, but I just said, “Ah, a brown snake,” and tried to pick it up – seeing me coming, however, it panicked and shot for cover in the pine straw. With any luck, the blasé reaction might have impressed on some of the students how little risk snakes actually impose. I’m not sure my reaction would have been any different had it been a copperhead, the only venomous snake in the region, except that I wouldn’t have tried to pick it up. Doing anything drastic would be more likely to provoke a defensive strike than simply holding still and letting it go its merry way.

pieris blossoms after a rainI close with the only photo from today, expressing the conditions pretty well. These are the blossoms of a ‘Mountain Snow’ pieris bush, one that we purchased the other day to plant in the backyard because it does well in the shade, which pretty much describes the backyard. It flowers in early spring (so, hah! It must be spring then!) and I wanted to capture the clusters of blooms before they all turned brown and vanished, since I won’t get the opportunity again until next year. While I want things that will serve as a good backdrop and attract insects and/or birds, The Girlfriend isn’t all that concerned with arthropod activity, somehow, concentrating instead on plants that will look nice and do well in our conditions. Hopefully, we’ve got some things that will serve both purposes – we’ll see how it goes.

Too cool, part 27: This is why I don’t bother

Astronomy Picture of the Day is something that should be on your weekly routine, at least – it often features some pretty stunning images. Today’s (or I guess I should say, the image for Monday March 16th, since it’s late and this will probably post early Tuesday morning) is especially cool, and gains additional interest when coupled with a few other details.

Annotated Orion with nebulae
Courtesy APOD/Rogelio Bernal Andreo at DeepSkyColors.com

This is the version I resized for the blog, but by all means you should go to the original or, for preference, the version you get when you click on that, which is much bigger. On the initial page, the annotations shown above only appear when you hover your mouse over the image, so you can see it without the distracting lines and labels.

constellation OrionNow, some perspective. You’re not going to see anything like that image above when you go out to look at Orion – what you’re going to see will look much more like the photo at right. Nebulae are faint sky objects, and only a handful are visible without help in the best of viewing conditions. More specifically, most details won’t even show at all without filters designed to select only the narrow bands of emissions that they produce (like, as that page says, hydrogen alpha.) So the APOD image is “shopped,” a composite of visible light and very selective wavelengths captured through long exposures.

And the primary issue with long exposures of star fields is that the Earth stubbornly keeps revolving, meaning the stars wheel across the sky, so the only way to get sharp long-exposures is with a system that moves the camera and/or telescope at the same speed, keeping the stars perfectly in frame. On telescopes with an equatorial mount, tracking motors can occasionally be added that keep the scope on your target, but these have to be aligned precisely with celestial north (which is not quite Polaris, the North Star, but fractionally to the side of it.) For anyone lacking such, there are plans available to construct a tracking mount/platform for non-telescope photography, using standard lenses, but there are accuracy issues which may limit how long these can be used before star motion creeps in. It’s a little tricky to describe why and so I’m not going to unless someone asks – for now, blame it on geometry and trying to construct a usable homemade system without custom-engineered parts. If you’re interested, however, do a search for “barn door tracker,” especially the double-arm style, which is much more accurate. I personally have not tackled such a project yet because my access to tools and decent stepping motors is limited.

Without it, however, one is stuck with brief, high ISO shots which cannot capture a hell of a lot. To wit:

Orion's Dagger and Orion Nebula, very faintly
This is seven seconds, f5.6, 200mm, ISO 3200 – and there’s still motion in the image, including possibly some tripod shake (the stars should move in a straight line and not a mild ‘U’ shape.) This is almost the exact same orientation as the image right above it (the plain one,) but a tighter framing of the center, focusing on the region of the Orion Nebula and Horsehead Nebula. The brightest star towards the upper left is Alnitak, the ‘leftmost’ belt star, the other two belt stars being out of the frame in a line directly above it. The cluster of stars at center-right are collectively known as Orion’s Dagger, more-or-less appearing as three points to the naked eye, but occasionally visible as being a bit less distinct than just three points, and you can see why – it’s a far cry from three stars. The faintest hint of the Orion Nebula is showing as the flare in this region.

Between and below the two brightest stars to the left lies the Horsehead Nebula, not at all visible above. In fact, even in the big version it shows as just a little dark spot against the pink cloud in the background. I was going to try and guide you to it, but figured it was easier to just present the same image from Rogelio Bernal Andreo, rotated, cropped, and enlarged to match the same perspective as my image above:

cropped version of Rogelio Bernal Andreo's Orion composite
There – the Horsehead Nebula is that little dark splotch against the pink cloud at left-center. Now here’s a version imaged by the Hubble Space Telescope, featured in an APOD a few years ago (click there for the bigger version):

Horsehead Nebula in infra-red

It seems kind of inverted, but this is because different wavelengths were captured between the two images. The infra-red filter used for the frame immediately above does not capture any of the hydrogen-alpha wavelength that provides the red colors in the image above it, those same wavelengths being blocked by the dust cloud that appears with such detail here. But this also gives a great impression of the magnification and detail that the Hubble can snag. For giggles, scroll up to zoom back out to a normal view to us on Earth.

And thus the blog title. Even with a decent telescope, even with a tracking platform, there’s no way I’ll ever capture images anything at all like the ones being produced by the professionals. But I’m happy to direct you to the better images, and hopefully provide a little perspective and awe along the way.

Monday color 7

green anole Anolis carolinensis on banana leaf
[These posts are usually lined up well ahead of time, so this one was completely written when I got the images in this post, which might actually be the same individual – they were taken not three meters apart.]

One of the images taken back on this day last October – I elected not to use it then. I know that I had been under the leaves of this banana plant, looking for silhouettes of insects on top since the sun was shining through so distinctly and the leaves are a brilliant chartreuse with a nice texture when backlit, but I can’t recall whether I spotted this green anole (Anolis carolinensis) then, or if I saw it from this perspective and then went back to see if it could be viewed from underneath – I suspect the latter.

green anole Anolis carolinensis toe silhouette through banana leafEither way, that photo was obtained too, though the lizard’s position atop the thick rib of the leaf reduced the distinction of the shadow – it really needs the image above to explain what it is you’re seeing. I actually waited to see if the anole would provide me with a better shadow pose, or would even launch itself after a leaf-footed bug that was walking along the same leaf (and provided its own silhouette images,) but the reptile was more interested in basking, possibly because the October nights were pretty chilly.

Within a month, the banana leaves were brown and hanging limply, with the appearance of corrugated cardboard that had been soaked in the rain and dried, and the anoles were nowhere to be seen, having sequestered themselves for the winter. Which just reminds me that I’m still waiting for spring and the reappearance of useful photo subjects, something that these Monday color posts were supposed to counteract. I gotta work on my psychology…

Starting the spider season off

unknown tiny white winter flowering weed
It’s been longer than I’d planned between posts, for several reasons, mostly being busy. There are also two larger posts that I’ve been working on, but they have required more time than I had available, so not just yet. But with the nice weather today, I took a moment to chase a few macro photos.

water drops on petals acting as lensesDon’t ask me what this flower is – it’s a whopping 5mm across from tip to tip, and I shamelessly added the ‘dew’ with a misting bottle since we’re still a ways off from those conditions. This was actually growing in the pot with my salvia plant, and I’ve photographed them before but still haven’t determined the species.

Because the water drops acted as lenses and were showing the details of the petals, I had to include a close detail crop. As smooth as they seem to us, every flower petal that I’ve seen actually looks like this in high magnification, quite scaly. One of these days I’ll get a decent microscope and start doing some photo-micrography (which includes learning how to pronounce it smoothly without stumbling.)

In the same pot, I found two crab spiders, which might have measured 9-10mm across at widest leg spread, which means 3-4mm in body length.

crab spider Thomisidae on pot edge
Macro work can give an entirely different impression. While seen this close they’re spiky and striated and not terribly cute, from an average viewing distance they’re barely visible, and quite delicate-looking, almost graceful in shape, and appear able to be smooshed with a hard exhalation. While writing this, I went back out for a shot to convey this perspective a bit better.

crab spider Thomisidae
on salvia with fingertip for scale
Hardly ominous-looking now, is it? And given the low viewing angle and the curl of the leaf, I suspect this one had no idea my finger was looming up from underneath.

Both for the appearance and to provide some hard-to-find water, I went ahead and misted my two arachnid subjects as well. It was impossible to tell in the viewfinder and even tricky to determine when looking at the magnified images, but it seems that this was appreciated.

crab spider Thomisidae possibly enjoying the mist
If you compare this one to the portrait further up, you can see that the ‘face’ (cephalothorax) seems to be angled downwards more, likely because the spider was sipping dew from the leaf like any good ol’ country boy (‘ceptin’ I think the phrase might have a different meaning to them folk.) But since this is how most arthropods obtain their water anyway, I’m probably not being presumptuous. This time.

Repercussions

Tree Lobsters! is a webcomic that I only peruse periodically, once a week or so, and when I found this one I had to check to see whether I’d posted my trash talk on artificial intelligence predictions before, or afterward. Luckily, mine came first – I hate looking like I’m stealing someone else’s idea.

[I also love the references to Voight-Kampf testing, with the caveat that, “Test may register a false positive with sociopaths.” If you don’t get this, you can try to fake that you do, but you’re better off running before someone can bring a weapon to bear.]

Second, I sent the same anole images from yesterday’s post to Dan Palmer last night with a very brief text accompaniment, within which was the phrase, “The lizard still surprised me.” Dan is in a northern clime so I was kind of explaining that we weren’t that far away from winter here, yet he took it another way entirely – actually, quite a few other ways. This morning I received a reply with, as he put it, potential continuations to, “The lizard still surprised me…”:

“..after all these years.”
“..with a kiss and a swift departure.”
“..with the DNA test.”
“..by copping to *both* murders.”
“..and ultimately ruined my childhood – it could have busted the Santa myth much more gently.”
“..as reptiles are wont to do.”
“..with the sincere apology.”
“..Valentine’s Day was weeks ago.”
“..I did not recognize him without the eyepatch.”
“..I thought that I had eliminated them from this planet during the mid-80’s.”
“..who drinks hot chocolate went it’s this warm out?”
“..Pampers makes lizard-sized?”
“..after the Bay of Pigs, I thought he was dead!”
“..he hadn’t even heard of Harry Potter.”
“..with a gentlemanly poke of his walking stick and an invitation to the club.”
“..he was wearing his Villiage People T-shirt.”
“..her lipstick and nail polish didn’t match.”
“..and I *love* surprises!”
“..before it’s battery ran out.”
“..despite the lingering awkwardness from the “barn” incident.”
“..he was posing under a spider web that said, ‘Pigs suck.’ ”
“..but only because I can percieve more dimensions of sarcasm than the human species.”
“..for the last time.”
“..the six-shooter in his holster wasn’t even loaded.”
“..it didn’t taste at all like bubble gum.”
“..without Mary and their 14 little darlings.”
“..the stock tip proved quite lucrative.”
“..pawn to G5, checkmate.”
“..nobody brings up the Partridge Family anymore.”
“..we had agreed to split the winnings 50-50 – now one of us was going to die.”
“..they were out of red sparklies.”
“..tequila, at this hour?”

Followed twenty minutes later by another batch:

“.. claimed his name was D.B. Cooper.”
“..had a very interesting theory about quarks.”
“..told me I could save 15% or more on car insurance.”
“..was almost unrecognizable with the new tat.”
“..I expected someone taller.”
“..that his name was an anagram of “Zildar”.
“..that’s what hermaphrodite means?”
“..he claimed to have let the dogs out.”
“..he had eaten all the Skittles.”
“..he had actually heard of Emo Phillips.”
“..had been rendered mute by the remote.”
“..had a thing for pickles.”
“..you know, I really wasn’t expecting that – hence the surprise – I guess you had to be there.”
“..lizards have blue snot?”
“..eyes *are* window to the soul.”
“..he wasn’t supposed to be back until Friday.”
“..if he was here, then who the hell was that in the pool this morning?”
“..I thought it was snails that left a slime trail.”
“..not everybody makes sergeant that fast.”
“..I couldn’t picture him running for office.”
“..help me, I can’t stop.”

At that point, I asked if he was trying to provoke me into posting them, whereupon the followup this afternoon was another batch. Okay, then.

“..he said he would get at least a B-, and he did.”
“..turns out he’s a well-known anime model.”
“..liked Ghostbusters 2 better than 1.”
“..he doesn’t have a Facebook page.”
“..he’s done unspeakable things with Q-tips.”
“..and after 35 years of marriage, that’s really all you can ask for.”
“..but not as much as the tarantula did.”
“..he really has been donating his lunch money to charity.”
“..he has the reflexes of Starbucks barrista with the shakes.
“..her lingerie collection is larger than mine.”
“..he drinks milk right out of the carton.”
“..he leads a double life as tax advisor *and* a taxidermist. You should see his business cards.”
“..she does not have a license to carry that concealed weapon.”
“..he spent World War II in a quiet valley in the Austrian countryside.”
“..she lives to spit.”
“..he only responds to ‘Scalydude’.”
“..he has only seconds to live.”
“..he has had intimate relations with Clint Eastwood.”
“..he loves to collect pennies – he chases after them when they roll.”
“..he wears shades, doesn’t give a ^&$#*”
“..overpaid for his porsche.”
“..what, without a viable brain and all.”
“..and that takes a lot of girl scout cookies these days.”
“..really, I can’t stop.”

All of which missed the point entirely, which was that I never knew lizards liked corn liquor…

It’s coming

Magnolia green jumping spider Lyssomanes viridis gathering old webbing
I’m not putting a lot of faith into this, considering the fluctuations of weather we’re already prone to here, plus the wildly unorthodox winter last year, but the first signs of spring are visible, and I’m lucky enough to have students who want to take advantage of it. Yesterday, the weather was fantastic but I didn’t get the chance to do anything about it, so I went out last night instead, seeking out some areas where the chorus frogs might be found dependably for photos. While unable to catch a glimpse of any, even though they were still sounding off as the temperature dropped to 10°c (50°f,) I saw a ridiculous number of spiders, mostly from their eyes reflecting the bright LED headlamp I was wearing. The one above was suspended over the trail, apparently gathering up webbing; I’ve heard that spiders often recycle their web by eating it, so I suspect this is what was going on, but did not watch long enough to confirm this. This image is at almost full-resolution, handheld and aimed by the light of the headlamp (which was getting blocked by the flash unit atop the camera,) so it was far from the ideal setup for doing macro work, and it wasn’t until I got back that I realized it was probably a magnolia green jumping spider (Lyssomanes viridis.) I wish I’d identified it then, because I would have brought it back to do more anatomical shots, and perhaps try to establish a presence of them around the place.

unknown tiny hunting spiderBetrayed by its eyes, this unidentified spider at least gave me more of an interesting pose when I went in close – most just remained in place on the ground as if pinned on display. The reflection must come from a very narrow angle between light and receiver (which means your eye, or the camera lens,) so the reflection effect is not visible in the image, and in fact very hard to get when close enough to see the details of the spider at all. A bright light may show a starburst of blue-green down on the ground (and occasionally on weeds, tree trunks, overhead branches, and even out onto the water,) a few meters away, which will disappear as you draw closer. Usually, this is just because the reflection angle has gotten too great, and keeping an eye on that spot will often reveal the spider itself, sometimes much smaller than the brightness of the reflection seemed to indicate. Last night, I saw dozens, with some patches of ground showing a half-dozen at the same time. The one seen here was the size of my little fingernail, and soon ducked for cover, but I also spotted a few of the fishing spiders, one at a significant distance of six meters or so (confirmed with a 400mm lens.)

And then there was today.

Carolina wren Thryothorus ludovicianus on burned stump
While the birds have been active enough all winter, the breeding season has arrived and countless species could be spotted, flipping through the trees and digging in leaf litter. This Carolina wren (Thryothorus ludovicianus) posed momentarily on a stump for a few frames, then flew off just as I tripped the shutter once more.

Carolina wren Thryothorus ludovicianus flying off

chorus frog from peculiar perspective
Back at the botanical garden, the chorus frogs were in full force, sounding off loudly every time no one was near, but falling silent as soon as anyone closed to visual distance, making it difficult to spot them at all. This one, however, remained floating in a tiny pond, eyes and back just breaking the surface, and I chose this angle solely for the bizarre perspective.

chorus frog playing it cool when people are aboutHere, another plays it cool while we were nearby, refusing to reveal its presence any more than it has, which isn’t much. Chorus frogs are quite small, perhaps 5 cm in length, and are easily mistaken for just about anything else in the water. I was only able to spot this one by knowing it would be there.

I have no better views than this, so I can’t pin down the species adequately – perhaps a southern chorus frog, but more likely an uplands chorus frog (Pseudacris feriarum) – none of them have markings as solid black as they appear in these images, which is mostly due to the overcast lighting of the day, perhaps partially due to the season. I still intend to get better images than these at some point – it’s just a matter of finding a habitat for them that I can stake out, perhaps after nightfall (ruling out all parks in the area.) Meanwhile, if you want to know what the call sounds like, you can go to this post from last year with the embedded sound file.

minuscule eggs, probably chorus frogEggs could be found as well, but only by looking very closely – the bi-colored center of these aren’t much larger than the head of a pin, and that’s pine straw that they’re attached to. Since the botanical garden is much closer to where I live now than last year, I might be able to keep an eye on the development of these – we’ll see. I had also intended to have a pond established on the property by now, but that project hasn’t gone well at all this winter, so it’s unlikely I’ll have the easy access to aquatic subjects that I’d planned to have. The best I can say is watch this space to see what pops up.

tadpole resting on bottom
There’s nothing remarkable about this image, but I’m going to use it to illustrate something about shooting aquatic subjects. Just to mention it, but this tadpole is roughly half the mass of the adult frogs seen above, and clearly a different species – probably a bull frog or leopard frog. Sunny days are best when trying to shoot something in the water from above the surface, because the light penetrates. The diffuse light from haze and overcast doesn’t get into the water as well, but worse, it reflects from the surface no matter which way you’re facing, making it seem as if you’re looking through milky glass. The quick fix is seen here.

another selfie
Granted, you shouldn’t focus on the surface itself, or even what’s reflected in it, but anything that blocks the sky enough to prevent the reflection will permit a better view, and the easiest way to do this is often with your head. If you look very close, you might make out “Canon” spelled backwards across the tadpole…

trout lily Erythronium americanumThere still isn’t much growing yet, but there were a few trout lilies (Erythronium americanum) peeking out. Not 10 cm high and extremely subtle when viewed from above, I had to get down on my knees, bent almost until my ear touched the ground, to get the details of the flower. This isn’t an old or deformed one – they grow looped over like that, which makes me wonder why, and what kind of pollinator it attracts. Perhaps they’re actually bioluminescent, and serve as kind of a street light for field mice with loose morals to hang around beneath…

green anole Anolis carolinensis being cagey
This was one species I was quite surprised to see out so soon – I guess the weather of the past three days has been sufficient to stir them out of dormancy. Green anoles (Anolis carolinensis) are definitely sun-worshippers, and I really didn’t expect to spot any until the insects were a lot more active (for instance, I have yet to see any bees around.) This one we photographed twice, coming back to check on it after our presence caused it to slink out of sight the first time around.

green anole Anolis carolinensis doing a short focus portraitThese images are out of chronological order, and it shames me mightily, I admit it, but they worked better in the layout this way (unless you’re using a smutphone or some other toy to view this site, in which case all bets are off.) I shot this one first, when the reptile was perched more out in the open, and obtained the one above while it had started venturing out but was still utilizing the camouflaging and obscuring fronds of the palmlike thing – I really have to determine the species, because that particular plant has appeared in a lot of my images.

I’m still half-expecting the weather to make one last desperate cold-and-miserable spasm before spring truly kicks in, so I’m treating this as a preview and not the main event, but it was still nice to see a little activity. Mid-latitude winters are just not kind to nature photography.

Monday color 6

just an irisThis image was taken almost exactly a year ago (March 11 to be precise,) as some early bulbs were bursting forth. A week later, another freezing rain storm had redecorated them, and everything else.

I should have made these ‘Wednesday color’ posts – then this one and the first could have been lined up to be exactly a year later. Because that’s significant. I could have even arranged them to post at precisely the same time that I took them, and everyone reading could have taken part in that amazing experience.

I really don’t have anything to say here…

A few more

hickory blossoms against sky reflectionThese are just a few more images that I obtained in the past week, that I didn’t try to jam into the previous post. Instead, I’m jamming them in here!

I have photographed these peculiar blossom pods umpteen times in this state, and never figured out what they were. Finally, for this post, I started searching (try to imagine what kind of terms you put into a search engine for their appearance,) and now believe these are the flowers of a hickory tree. The disturbing thing about this is, we had a hickory tree in the back yard of the old place, and I never made the connection. And in thinking about it, I knew we had different flowers on that, but the explanation is, these are male flowers, while the female flowers are different (less prominent Adam’s apple.) The female flowers – naturally – produce the nuts. Makes perfect sense. Don’t use these to try and teach kids about sex.

Anyway, here they’re against the blue sky reflecting in a pond, which is a better way of producing background color than trying to frame against the sky. The sky is bright and often the difference in light levels will mean either turning your foreground subject into a silhouette, or exposing for that and bleaching out the sky, perhaps to pure white. But reflections are darker than the sky so become more manageable, and can be darkened further with a polarizing filter since reflections from water are polarized – turn the filter until you achieve the effect you desire.

Canada geese Branta canadensis with pine reflections in pondAt the same pond, a pair of ubiquitous Canada geese (Branta canadensis) paused among the reflections of the trees, and I zoomed out and shot vertically to use the reflections, doing that fartsy thing again in abject denial of my lack of artistic skills or reverence. It’s a more complicated shot than I prefer, but you take what you can get when you’re out chasing pics, and keep the concept of better conditions in mind so you can recognize them when they occur (or better, change position or timing to help produce them.)

In fact, all of these images depend on rather crucial positioning, sometimes in very subtle shifts. For the hickory penises blossoms at top, it was not just the use of the sky reflection in the background, but also the selective focus on the closer one, with a short depth-of-field, and the shift so that the two clusters sat in their own distinctive positions in the frame and weren’t touching or overlapping – the guys know what I’m talking about here. And with the geese, it helped to have them lined up with the trunks, but more important was the patch of blue sky that lent a little more color and defined the shape of the trees – without it, the reflection would have been ‘just foliage’ and less appealing, practically unnoticeable.

backswimmer bug Notonectidae out of water on leaf
It might not seem like positioning was all that difficult for this backswimmer (Notonectidae) perched on a floating leaf, but you weren’t there, were you? Taken in a raised pond at the botanical garden, the vague greyness at the left side is actually the wooden edge of the frame, since the leaf had drifted into a corner and I was endeavoring not to have artificial aspects in the photo. Worse, however, was the sun angle – any other position than this meant my own shadow was cast across the insect, which not only would have changed the shot significantly, it might have spooked the bug into the water and ruined the opportunity. I spend a lot of time aware of where my shadow is falling, so it doesn’t appear in my images and doesn’t frighten any living subjects, and I recommend developing this awareness for anyone pursuing nature shots.

Anyway, considering that several of the ponds right next to this one were still frozen over because they received less sunlight, I was surprised to find this guy out, and in fact I’ve seen very few of this type of insect around at all. The legs are vaguely flattened and serve as oars, and they are usually spotted just under the surface swimming along awkwardly and jerkily – as their name implies, on their back upside down, where they can see their prey easier. Check out this page for more characteristics, and this one for a close relative, especially the identification portion to see one of the reasons why arthropod photography can be challenging.

weeds against water sparkles bokehThis was one of the images taken on the River Walk, just trying to do something with the lack of compelling subjects in winter. The background is the river itself, crashing over a log and throwing reflections of the bright sun. Well out-of-focus with, again, that short depth-of-field (wide aperture, in this case f4,) the sparkles became soft balls to frame the simple subject of the dried weed. Only a very narrow angle would produce this effect, and I recommend taking several images with infinitesimal shifts, because the placement of those background globes will vary as the water dances, and cannot be predicted – some will produce a good frame, some will clash or just get messy. The sun is in a direct line with the camera though well above the angle of view, the only way the reflections will be seen, but also backlighting the weeds so they aren’t just silhouettes. A lens hood is a good idea in these circumstances.

daffodils spring from pine needles among snowAnd finally, an image from today, one that I shamelessly (and unrepentantly) staged. The snow had since melted before the emerging daffodils (I think – I could be wrong about the species) had gotten this high, so I got a few shovels of the iceberg mentioned in the previous post, left over from digging out the car, and dumped it into the frame in choice locations. This both broke up the background in a more appealing way than the monotonous pine needles, and expressed the time of year that such flowers appear. Thus, while it is not strictly ‘as found,’ it is still representative and expressive, not much of a gross manipulation – you can, of course, form your own opinion (no matter how wrong it might be.) By noon, the nearby trees cast the flowers into shadow for the remainder of the day, so this isn’t exactly crucial timing, but I missed my opportunity for this yesterday by being busy with other things.

It’s funny; most other forms of photography allow for varying degrees of staging and manipulation, people drawing or painting can put things any damn place they please, and I can even adjust lighting in numerous ways not at all representative of ‘natural’ – but to a lot of people, dumping the snow there is considered ‘faking’ it, and even I feel slightly chagrined that I’m setting up an image rather than shooting it as it is. It’s definitely cultural, and it’s weird. But if we get more snow as the blossoms open up, I’ll be sure to show you the authentic images.
