bumblebees raiding coneflowers
This one’s been sitting in my blog folder since June, waiting for an opportunity, and it will serve nicely in this interim until I get time for more substantial posts. The coneflowers clearly look a bit past peak, but the bees didn’t seem hampered by this, so it’s probably our perceptive biases.

This is another instance where the muted, low contrast light of a deep-haze/semi-overcast sky worked better for the colors than bright sunlight would have – there are more subtleties, less harshness. The shadows don’t become too deep, nor the highlights too bright. Once again, low contrast light for high contrast subjects, and vice versa; it also helps to have some pre-programmed settings on the camera that will assist in those directions, ones you can switch to instantly. This way, you can change subject matter more often without having to return when the light is better.

Podcast: Necessary research

green sea turtle Chelonia mydas patient at Georgia Sea Turtle Center, Jekyll Island
Okay, I finally got enough time and an adequate frame of mind to tackle the Savannah/Jekyll Island trip – or at least part of it. You may note that, while I talk about cleverly handling a schedule in the podcast, I never actually said when I would get around to this, so I’m not behind schedule at all.

As before, I am including a few images to help illustrate the narrative, if I may use such an overblown word. This time around, it doesn’t matter too much if you jump ahead. But maybe later it will, so this could be good practice for you.

Walkabout podcast – Necessary research

Did you get to the part discussing the Georgia Sea Turtle Center yet? Good – you can now scroll down to the next three pics below. You can also check out my previous visits to the center here, and here, mostly for the images – the information hasn’t changed in any significant way.

green sea turtle Chelonia mydas missing right forelimb, during veterinary exam

diamondback terrapin Malaclemys terrapin juveniles hanging outAbove, a green sea turtle (Chelonia mydas) during its veterinary exam – I did not think to check the info board on this one to find out what the missing forelimb was attributed to; while many injuries to sea turtles come through encounters with boats, fishing gear, and garbage, wounds of this nature are often caused by sharks, which can target the limbs easier than the armored torso. Many of the shark attacks on humans come from the exact same trait, as sharks see the arms and legs of surfers dangling in the water to either side of a surfboard from underneath, and register the silhouette as a turtle. Most such injuries to humans are bite-and-release, not because the sharks are as sporting as fishermen (or at least we don’t think so,) but because the taste and texture is all wrong and sharks don’t consider humans as a food source.

To the left, two of many very young diamondback terrapins (Malaclemys terrapin) hanging out in their little “day care center” until they are big and healthy enough to release – you gotta love that shell pattern. They measured approximately 3cm in carapace length. The numbers painted on their backs were used just to tell them apart for medical records and not, as I was told, because the staff raced them after hours, disappointing me greatly. Why would you waste such an opportunity?

Below, a shot showing the lovely shell pattern of another green sea turtle – the plastic pipe in the pool is weighted and primed with vegetable matter when feeding time comes around, letting the turtle pluck its food from the bottom in imitation of natural behavior. Green sea turtles, by the way, primarily get their name from the color of their fat, and occasionally their skin like the exam image above; the shells are usually various shades of brown as seen here.

Now, you can wait here until I talk about heading out to get sunset photos on Driftwood Beach…

While you’ve already seen the better version of this photo sequence, I’m posting this one because it shows what the sunset itself looked like; the sun’s someplace behind that weird cloud bank. The horizon colors allowed from some vibrant backgrounds only with selective cropping.

ContemplationMeanwhile, I haven’t the faintest idea who this is, but she was posed enigmatically on the railing as I approached the fishing pier on the north end of the island, so I positioned myself for the best framing I could, lucky enough that no one else was visible on the pier at the time but unlucky enough not to have any rich colors extending to the sky behind her. It’s a useful illustration of how photography often works; the pier had plenty of people on it, mostly night fishermen, but without capturing any it appears completely empty and the isolation of the lone woman is paramount. Yet, when compared against the other images taken the same evening, these colors seem flat, but had you not seen those, you probably would not have been aware of any lack and could accept the delicate sky as it was.

Below, the view from the same fishing pier northeast across the sound to St Simon’s Island and the lighthouse thereon, as a few late beachcombers stroll on the sand. Some of the driftwood that gives the beach its name can be seen, but it occurs to pedantic me that this is a misnomer; the dead trees all come from right there, as the shifting shoreline encroaches on the forested area, so none of this is actually driftwood. Now, when the wave action tears them free and carries them someplace else, then they’re driftwood, but they’re appearing on some other beach by that time. I suppose, for the sake of convenience, we’ll just assume that they were all carried back by the waves and are appropriately named.

Okay, if you’re still practicing your good behavior without jumping ahead, you should be waiting here until I mention getting back from chasing crabs and starting a photo session in the bathroom.

living sand dollar order Clypeasteroida beginning to bury itself
From much later that evening, one of the images I was taking in the bathroom of the motel as the others slept. You can easily tell this is a sand dollar, a type of sea urchin (order Clypeasteroida,) and it’s just starting to industriously bury itself in the sand after I placed it in a good position to photograph; the mouth is the opening to the left of center. By the way, if you hold one in your hand for a bit, you can feel it begin to crawl sideways in an attempt to find sand to conceal itself within.

And one more capture from the day, again stirred up from the seabottom near shore quite easily. I have no actual idea what this is; I had initially thought it was an anemone of sorts, but nothing that I’ve found so far matches, and I wish now that I’d taken more broad illustrative photos (I did not bring any specimens home with me as I am not maintaining a saltwater tank.) Overall, the species had the appearance of a thick kind of lily pad about 15mm across, with a stem (without roots) extending up to a thick oval body along one downturned edge. The underside was pale, while the top side was pinkish-red but covered in pale spots; each of these spots produced an individual trunk capped with, it appears, eight pseudopods or ‘arms’ after resting undisturbed in the water for a short time. Every anemone that I’ve found seems to have the trunk and arms, but are thus individual specimens – this was, to all appearances, a single organism producing a group of feeding trunks. If you have any ideas whatsoever, let me know, because I’m stumped.

An abstract for August

hermit crab trails on Driftwood Beach Jekyll Island Georgia
Okay, this one is quite a bit more abstract than some of the previous, so I feel better now. In fact, it is only that small leaf at lower left that provides some scale to begin to give a little context – I wish I’d shot a few frames without it, but I wasn’t thinking about it at the time. So go ahead, using that clue that I wantonly handed you, figure out what it is you’re looking at.

Of course, your experience with drainage and crustaceans instantly announced that this is an image of hermit crab trails across a tidal flat – Driftwood Beach on the northern tip of Jekyll Island, to be exact (and chances are, thinstripe hermit crabs, Clibanarius vittatus, judging from the others that I found.) Less than an hour after sunrise, the low light angle gave a lot of definition to the minor variations in the sand, and the breeze hadn’t yet dried it out and started erasing it, so this was probably the best time to photograph such things. In fact, “When is the best time to photograph hermit crab trails across a tidal flat?” is probably the most frequent question asked within the comments (as you can see,) so I’m happy to provide this little illustration. Always there for my readers…

I don’t think so

Neuse River rocks and ripplesMr. Bugg actually had the temerity to say that he was going to post something from today’s outing before I could. Yeah, that’s right – the same guy who’s been letting his ‘Wednesday Color’ posts slide for weeks now. I put it all down to the arrogance of youth. I am the post master. Never mind that my trip posts are still waiting; they’re ripening, awaiting the perfect time to appear, mellow and full-bodied. That’s how it’s done properly.

You won’t catch me altering dates on my posts to try and hide the fact that I missed my schedule, either. Unlike, you know, some people…

Little so-and-so…

Not yet

unidentified crab alongside foot on Driftwood Beach Jekyll Island
I have been hoping to get some time to start posting again, especially after this trip, but it has been eluding me – when I actually have a few minutes set aside, there have either been too many people around (impossible to try and write anything,) or I’ve been ill. Posts are coming, within the next few days is my plan, but in the meantime, another beachy shot. I haven’t tried finding out what species of crab this is – it looks a lot like the marsh crabs I used to see in Florida – but I suspect the photo is evidence enough that I had initially mistaken it for an insect. I mean, it is an arthropod, but like most people, I treat crustaceans as something else entirely, and not the cousins of the various insects we see every day.

Even as simple as this image is, you can tell it’s a sunrise shot – those little clues are absorbed subconsciously.

More later on…

Working on it

fishing boat in St Simons Sound at sunset
Once again, the sunset wasn’t up to snuff, but by being selective over the view and finding another element to work with, I got something that I like. The locale is St Simon’s Sound off of Jekyll Island, which should give you a hint as to where we spent the weekend – this was from Sunday evening and I’m just getting around to posting it now, if you can actually call this a post. More will be along eventually – just trying to get past a few other things first.

But this makes two trips to work on scenic and landscape shots; after a long spell without any such opportunities, I feel spoiled this year. That’s not right – gonna have to try and correct this.

Wednesday color

Haven’t done one in a while, so let’s go big…

I dunno, Wednesday just seems like an odd day to do a color post. I mean, it’s current, since this was shot yesterday morning, but just… Wednesday, you know? It kinda bugs me. I’ll probably have to go back to Mondays…

Getting back to abnormal

juvenile Chinese mantis Tenodera sinensis night portrait
For the past few weeks, I have had little time to chase arthropod pics, and even less time to blog about it, but I’m able to catch up a little now. Some of these images are from before that busy time, and some are ‘current.’

I haven’t been keeping up with the mantises as I did last year, but that’s partially because only two are able to be found dependably. Above, one of them provides a distracted pose at night (as indicated by the dark eyes,) obviously less concerned with me getting into its personal space than with something off to frame right. This one was still a juvenile, but getting pretty big now.

Some nine hours earlier during daylight I had followed what might have been the same one, but it was paying even less attention to me, which does not help my crippling insecurity one little bit. The sudden change of head position to a sharp downward angle is a good indication that it saw something, but for a short while I couldn’t make out what, and rashly thought it was chasing shadows.

Chinese mantis Tenodera sinensis watching possible prey
The mantis was perched on the voluminous phlox plants, which provide lots of layers and hiding places, and after a bit I caught some motion myself, which turned out to be a small jumping spider making its way among the leaves and stems. Its path carried it away from the danger zone near the mantis, and eventually it emerged into a clear enough area that I could fire off a few frames, including one dramatic pose as it waved its forelegs in the air.

unidentified jumping spider portrait
While this might be considered a threat display or even a greeting, it was more likely ‘sniffing’ the air, since spiders have sensory hairs on their forelegs. I have so far been unable to identify this species, even though those yellow pedipalps and median legs are distinctive. Feel free to enlighten me.

unidentified jumping spider in breeding nestAs it ambled along, I saw a rolled leaf in the middle distance (for a small spider, at least) ahead of it, and suspected that this was its destination. Unwilling to disappoint me, the spider quickly made its way up the stem in question and disappeared into the rolled leaf, appearing briefly at the other side long enough for me to fire off a shot. Some spiders make breeding nests out of rolled leaves, as you no doubt remember, stitching the sides together with webbing to make a shelter for their eggs. In some cases at least, it seems this also serves as the honeymoon suite, to which the eager suitor must gain permission to enter or face the wrath of the female. If I ever find myself with too little to do and appropriate weather (meaning, not as hot as fuckinghell,) I’ll have to stake out one of these bowers and try to get a sequence of photos of the courtship – I’ve managed it once, solely by chance, and watched a couple of unsuccessful attempts.

A little later on, I shifted the leaf shelter up sightly so I could get a look down inside, producing a curious perspective on the inhabitant. You have to appreciate how the reflections from the primary eyes form the appearance of a pupil, lending a horrified look to the spider that isn’t seen at all in the earlier portrait shot above.

unidentified jumping spider within shelter
The two mantises I can find dependably reside, for now anyway, on the Japanese maple tree, which sits above the phlox patch. I missed their emergence into adulthood (I probably wasn’t going to top last year’s observations of this anyway,) but I’m still keeping an eye out for courtship and/or the laying of the eggs. Today I chased a couple of images just for the updates, even though I wasn’t capturing any behavior or captivating poses – as I said, it’s been a while and I needed to get back into the swing of things. One of them wasn’t posing very readily and was in a tough position under one branch of the short tree, but I fired off a shot anyway, which resulted in a peculiar ‘moonlight’ ambiance; this was because the front window of the house was in the background, and I was at a direct-enough angle to bounce the flash burst right back into the lens, thankfully not too brightly.

Chinese mantis Tenodera sinensis in faux moonlight
Chinese mantis Tenodera sinensis from slightly varied positionI’ll also take this opportunity to illustrate a simple but important, and often forgotten, facet of macro photography. As I did some portraits of the other mantis since it was slightly more cooperative, I was able to do some comparison shots. Both of these were taken only moments apart without the mantis moving more than a fraction; the difference comes from my position. I saw the antenna falling in front of one compound eye, as well as the leaf in the immediate background lining up right behind the mantis’ head, and shifted position slightly, framing the head against darkness instead and dropping below the antenna – the change also allowed the flash to illuminate the forelegs better. Such a trivial amount of effort to significantly improve the photo, and all it takes is an awareness of the background (including knowing that it will become sharper as the aperture closes down.) Increasing contrast at the point of focus always helps draw the viewer’s eye, done in this case by framing the bright green head against the blackness instead of the green leaves, and the complementary lines of leaves and mantis body are a nice bonus. Don’t get me wrong – I don’t consider this high art, but it’s a nice comparison illustration, and the more of this you can accomplish the stronger your images will be.

While in the garden store this morning, in a nursery greenhouse section, The Girlfriend and I heard a strong call within the building, one that I was pretty sure I recognized. I stopped dead and started tracing the sound, and was lucky enough to have the call repeat as I was closing in – no, I did not have the sound recorder with me, nor the camera; rotten foresight for a nature photographer, I know. I took down one hanging plant, started poking around in the leaves, and sure enough found the culprit, a green treefrog (Hyla cinerea) tucked up against a leaf. It had either ridden along when the plants were brought into the building, or had come in through the vent in the greenhouse ceiling, but it wasn’t a very good habitat for a treefrog given the lack of food insects. With some comical fumbling we managed to capture it and tuck it among the items we were buying, bringing it back home to release it onto the plants in the backyard pond.

green treefrog Hyla cinerea perched reluctantly on pond plantBy this time I had the camera ready, and did a quick photo session with the transplant, who may or may not decide to remain in the area; either way, it has much better access to food, shelter, and potential mates than the interior of Home Depot. Treefrogs do not spend much time at all in the water, but they do need to remain moist, and will deposit their eggs in or near the water so the hatching tadpoles are in the right environment. I’m fairly certain we had a grey treefrog hatching last year, and at present there are five juvenile green frogs (Lithobates clamitans, the more aquatic and non-tree-climbing cousins) living within the pond, though the tadpoles seem to have vanished quickly for unknown reasons. We’ll just have to see what happens.

So I’ll close with one more portrait, because you can never have too much green in a post, right? That’s the way I look at it, anyway.

It goes like… this?

butterflies on flower cluster
I doubt there are a lot of photographers that run into this kind of thing, but on occasion, I’ll be editing photos and find myself unsure of how the image should be oriented. You see, I might take photos at any angle – lying on my back aiming up at the underside of leaves, or leaning over sideways from a small patch of secure footing to get the right perspective on a reptile or insect – and at times it’s not obvious if I intended a horizontal or vertical format for the image. It’s an issue that I don’t imagine many portrait photographers run into.

I don’t have the auto-orientation options activated on my cameras and thumbnail viewing program, and I’m not sure it would help – how accurate is it for a camera aimed roughly skyward from ground level? (The program I use for viewing and sorting, by the way, is FastStone Image Viewer, which is truly excellent and highly recommended.) The backgrounds are often no help at all. Our impression is that flowers grow up and butterflies land on top, but we all know those ideas are not dependable. And some of the photos work fine either way. I’ll be tooling along, reviewing frames, and stop to wonder if I should be rotating these or not. They look okay…

butterflies on flower cluster… but then I rotate them and say to myself, You know, I think they go this way. I mean, if you want the most accurate rendition for these images, the first thing you’d have to do is lay your monitor back almost flat, since I was probably aiming largely downward from above, but that’s the best I can tell you. And if I’m having this much trouble knowing, then it likely doesn’t make any difference – pick the orientation that you like best and boom, you got the right one as far as I’m concerned.

One of these days I’ll have to have someone shoot a few frames of me while I’m tackling some of the more inconvenient subjects, just to show the goofy shit I do sometimes. About the most awkward one that I recall immediately was shooting with the camera completely upside-down, hanging from the inverted center-column under the tripod, but on more than a couple of occasions, I’ve realized that the muscles in my neck or lower back were really protesting, indicating that my position was far from normal. If I get what I was after, then I’m good, but, yeah, when the shoulder-bag is in imminent danger of swinging from its position on the back of my hip down to crash into my subject, or even into the water, that’s not exactly a pose you’d find in clothing catalogs, is it?

So, size does matter?

supernumerary rainbow with enhanced contrastFriday evening, the rain decided to throw down (it was certainly much harder than falling,) and typically for the weather we’re having this year, it passed quickly. As the sun returned, I checked to see if we were having a rainbow, but saw nothing. Turns out it was only being fashionably late, and wasn’t terribly bright when it arrived, but as The Girlfriend and I looked towards the top of the arc, we could distinctly see something that I first witnessed almost exactly a year ago. I ran in to get the camera, and it had faded to a degree in that short time, but I still managed to capture enough to illustrate this again. This image has slightly enhanced contrast to make it more evident.

Supernumerary rainbows are a partial repetition of the prism pattern on the underside of the main bow (there are often two, with the primary one being brighter and lower,) an optical ‘echo’ of sorts. Last year, my sources had indicated that we didn’t actually know how they occurred, which it turns out is partially true. Looking it up again this year, I found a better source which not only explains that the size of the rain droplets has a lot to do with it, you can even see the difference in effect with raindrop size by playing with their little doodad on the site. According to them there editors at Atmospheric Optics, the smaller the raindrop, the more distinct the inner bows tend to be – which is exactly the opposite of what I would have expected, given the conditions in which I’ve seen them both times. However, I was not out witnessing the rain at the tail end of the summer squall, so maybe the raindrops got smaller as it passed, shoved out of their place in the lunch line by the bigger bully drops.

Photographing rainbows is a bit like sunsets (mentioned in the previous post,) but probably takes even more effort. Bracketing heavily in both exposure and contrast settings is recommended, since the camera is less capable of discerning the subtle contrast differences that our eyes can see, and the exposure meter will be affected by pointing up into the sky. Achieving ideal brightness and saturation is therefore tricky, and it’s very easy to get nothing at all like what you were seeing unless you really work at it.

supernumerary rainbow with enhanced saturationThis is the same image, but with saturation thrown way the hell up – there will be another version at the bottom of this post. Now the additional bands below the main bow are plainly visible, reducing in width and starting to give a three-dimensional effect, as if numerous bows were stacked alongside one another into the distance, and we’re seeing their undersides. This is not the case, since rainbows are an optical phenomenon of light diffraction refraction and thus don’t really have a ‘distance’ – you can’t get closer to them, thus all the folklore about “over” and “beyond” and “at the end of” rainbows, which like the horizon are always distant and unattainable. In other words, it’s all cruel mocking.

As another small aside, shooting photos of this nature is a very good way to find out just how much dust and schmutz is on your digital sensor, more than a little annoying to me because it’s very tricky to remove it in the image, especially around the color bands themselves, and because I just cleaned the damn thing before I went to the beach. It must be pleasant to be a studio photographer who changes lenses in a nice clean environment all the time…
