Frog closeout sale!

I’ve collected a few too many frogs, so I’m slashing prices and passing the savings on to you. Let’s see if I can complete this before October really and truly has left.

Back on the 10th, I found this little spud sitting on the decorative sweet potato plants alongside the front door, slightly larger than a thumbnail. It behaved well enough to allow me to come in close and do some detail images, but first, the view as originally found.

It would be easy to say, “That’s a green treefrog,” and you’d be technically correct, while at the same time completely misleading. A close crop of the former image helps us with a particular telltale trait, though.

What we’re looking for here is that pale patch under the eye, delineated by a darker stripe behind it, but also the striped patches along the hind legs give a good indication too. Those, especially the eye patch, are all traits of the Copes grey treefrog (Dryophytes chrysoscelis,) so while you were correct in saying it was a green treefrog, seeing that it’s a treefrog and it’s mostly green, it’s not the species commonly known as the green treefrog, and thus you’d also be wrong. The juvies sport a lot of green skin until they reach a certain age, though I don’t know exactly what that age is, but it’s been a source of uncertainty before.

Now, the common grey treefrog also looks exactly like this, and they’re next to impossible to tell apart from the Copes, except for the call, but it also seems we have nothing but the Copes in the area (in fact, all of NC according to sources,) so I’m comfortable with this identification.

Several of the true green treefrogs (Dryophytes cinereus) have been using the windows in the kitchen and the breakfast nook as their hunting grounds at night, so we often leave the lights on for them – not that they’re afraid of the dark, but the moths apparently are, when by all rights they should be much more afraid of the treefrogs. When the overnight temperatures dropped, the frogs disappeared, but came back very quickly as soon as it wasn’t that cold, especially when rain was threatening. I took the opportunity to snag one the other night.

They will sit like this, practically suction-cupped to the glass, but should a moth appear nearby (which happens frequently,) they demonstrate that they were paying close attention and start stalking them – we’ve witnessed several captures, which one day I will get on video, but arranging that with adequate lighting will be tricky. This, of course, is done with a flash, and I even backed off to create more of a tableau.

There- we even have a ghost for Halloween. A double one. With the gold rings of its headlamp faintly visible too – talk about a detailed apparition!

I have been unsuccessful in snagging a daytime photo of one of the greens sleeping deep in the crook of the elephant ear stalks, which vaguely resemble the way palm fronds grow, but I did capture one after nightfall when it had ventured back out again. This was quite chilly and I was a little surprised to see an active frog, but here we are.

I had to play around with the perspective and do something with it, since I had (so far) failed to snag it tucked deep into the grooves of the stalk. You can’t tell from this angle, but the stalks grow in more of a “U” cross-section, funneling rain down into the base of the plant where it can pool for days, and so the treefrogs consider this a nice moist clubhouse, well protected from even nature photographers.

Meanwhile, the ginger lilies (Hedychium coronarium) have been re-blooming, a little surprising considering that many plants are dropping leaves or at least turning autumn colors, and last night when we distributed corn, I found frogs on two of the plants, right alongside the blossoms; apparently they also know that moths are attracted to the scent of the flowers, which really is quite pleasant. Naturally, I returned with the camera in hand a little later on.

The flowers don’t last long and droop, wilted, after only a day or so, which didn’t help the aesthetics of the shot very much. Nor did the frog turd this little guy had deposited right behind it on the leaf, but at least that, I could carefully snake my pocket knife blade in and scoop it out of the frame. I made the attempt on that tan thing too, but it was tangled with some webbing and I was already in danger of spooking off the frog. Better luck next time.

At least I got this one – the other frog on a neighboring plant had scampered off in the interim, so I simply concentrated on the better-looking flowers instead.

They really are blooming enthusiastically, which is good to see – perhaps we’ll have a small grove of them in a few years. This is alongside the midyard pond we call the Puddle, a good place for them.

I returned the next night, which is actually tonight, and had better luck on this same one, at least.

It’s there – look closely. Definitely relying on its camouflage this time, which works quite well – just a tad too yellow. They need to work on this. But we’ll go in for a better look.

All of these were juveniles, by the way, these last two being roughly half of full adult size. Can’t imagine they were finding a lot to eat, but they seemed to know what temperatures would work and what wouldn’t, so we’ll trust their judgement.

There – squeezed them out. All typos that this produced were intended and should be considered artistic license. And now into November – remember to reset your camera clocks too, if you’re in an area that still participates in this asinine Daylight Saving Horseshit…

large collection of wood ducks Aix sponsa with a pair of mallards Anas platyrhynchos preparing for the dawn raid on the distributed corn
Another quiet week, so we’ll make up for it with a video – how’s that sound?

While the wood ducks (Aix sponsa) had thinned throughout the summer, they were still making appearances, albeit mostly the juveniles. Abruptly, the Canada geese (Branta canadensis) joined them, a couple weeks ago I believe, and then a very large number of adult wood ducks. And now, a pair of mallards (Anas platyrhynchos,) which we believe are the same pair that had been visiting together in the spring, even when others were scarce. We don’t pretend to understand what motivates the waterfowl and their schedules, but we do have to provide updates from time to time.

The numbers have simply exploded, and we’re going through corn like gangbusters. It’s impossible to get a decent count, but I can tell you that, in the top image, there are 41 wood ducks, four geese, and the pair of mallards. What’s most interesting is seeing the change in how bold the wood ducks have become, since until very recently, they would wait a little anxiously for the geese and nutrias to clear out before beginning their raid, which would last somewhere between one and four minutes before something would spook them and they’d fly in a mad panic down to safer areas in The Bayou. At best, it wouldn’t be a full panic, and most would simply make it to midpond to reassess the situation. I haven’t seen a full panic now for days, and as the video shows, at least a couple (I realized after narration that a female was participating too) were being quite forward with one of the geese. We also used to witness the nutrias having their fun when the ducks were feeding nearby, by popping up in a brief feint to watch the ducks scatter, either just trying to maintain a little personal space or, we suspect, actually doing this in a playful manner – we’ve seen other examples, and it really doesn’t look territorial at all. But now, it’s fallen flat for them, since the wood ducks just dodge a little but don’t bother flying off or even running for the water.

active morning raid on corn by wood ducks Aix sponsa
Curiously, too, last year it was virtually always the females that led the raids, being the first onshore before everyone else followed suit – perhaps it was only the same one or two, we have no way of knowing. This year it’s certainly the males, and there does appear to be a noticeably larger male that often stands lookout on a cypress knee. This might, in fact, be the difference in their behavior, if they really do have one specific ‘lookout’ that they all pay attention to, and the one for this year is a lot less spooky.

For a short while, most of them were confining their raids, especially in the afternoon, to a spot semi-shielded from view in the house, especially from the upstairs window that the video is shot from, permitting only a peek through the gaps between trees that we call the keyholes.

The geese quite often come along much later in the morning and are far more casual about eating, usually staying for a few hours and just hanging out, even waiting as we distributed the morning corn. The Girlfriend was quite pleased one morning when one not only came onshore while she stood there, but sidled up within two meters to eat; after a few minutes, the territoriality of others caused her friend to come so close it brushed against her legs. I’d woken up a little later than The Girlfriend, spotted her out the window, and watched her standing motionless with the goose in front of her, snacking on corn and even taking a brief nap. It’s a hoot.

By the time the sun is hitting the water in the morning, most of the wood ducks have left, though there may be a handful of stragglers that hang out with the geese, who may remain until close to midday, and occasionally return in mid-afternoon. By late afternoon the ducks start appearing, gathering quite slowly, but early enough that the late afternoon sun can illuminate their plumage nicely.

The activity visible through the keyholes is often almost frantic, and the timing of portraits like this is very crucial, since they’ll be in and out of view in less than a second. These afternoon raids are a lot more variable than the morning ones, sometimes vigorous, sometimes very thin and casual, sometimes never taking place at all. Generally, if I have gotten my timing down and have opened the bathroom window beforehand, they don’t perform well, only doing so when I’ve neglected to be prepared and can’t possibly chance opening the window because they’ll spook and fly off – it’s a new vinyl window, it has no reason to make so much noise opening, but so it goes.

I’m in the process of planning a duck blind to go on the deck, which will be slightly closer but have a better overall view then the upstairs window – as long as I’m in it before the ducks start to arrive. We’ll see how that goes. In the meantime, corn donations are appreciated…

Well, we’ll let you go, October

Al DenelsbeckLeave a comment

Oh, yeah, I almost forgot – before we go…

[That’s how far too many conversations go, isn’t it? Aliens would probably consider it a human ritual…]

Yes indeed, October has to go pick up the kids, so it’s dropping a couple of abstracts by the pool in a hurry before anyone can ask any questions. They look a little something like this:

backlit leaves in shadowy area showing overlapping shadows
One of those times when a narrow patch of sunlight lances through and highlights a few leaves to produce bright contrast and color, but here’s what I like about this: despite the appearance of the cluster to the right, there are no smaller leaves at all, and they’re all roughly the same size. The dark silhouettes of the ‘smaller’ leaves in there is only where the large ones cast shadows on those below. I need to keep an eye out for more effects along these lines.

And another. Both of these, by the way, were known to be up for the month-end status when I took them – I was actually prepared this month. Not so much for other posts, but you take what you’re given and be thankful. There are aesthetically-starved children in Africa that would appreciate these…

thin twilight colors reflected in dark waters after sunset
When chasing the sunset on the waterfront a few weeks back, I noticed that the bare hint of color in the sky was reflecting from the water, seemingly out of proportion to its appearance directly. Part of this may be due to the angle being just right to be catching those particular spots, and part of this might possibly even be from the polarization that occurs when light reflects from water. I also just realized this is essentially a five-color palette, and could be reproduced with little visible difference using nothing further. It’s easy to tell what this is, but the varied colors seem to add a lot more depth and contours to it.

If you want to buy a print, I’ll be happy to expound a bit more so you can captivate your visitors in a knowledgeable and erudite manner, perhaps about how our five basic emotions define and accentuate the landscape of our existence. No charge.

Tip Jar 41: Check them!

Al DenelsbeckLeave a comment

Okay, this is one that I do not have mastered well enough yet, and still get caught on – not often, but more often than I should, given how long I’ve been doing this. And it’s simple: Check your settings!

As in, each time you take the camera out of the bag, and each time you put it back (either one would be enough, if done consistently, but both is a safety margin.) It’s not a bad idea to ‘normalize’ your settings routinely, either, but pick something and make a habit of it.

What I mean is, know exactly what mode your camera is in, what options, what exposure, what compensation, and so on, before you start snapping frames. It’s easy to have a situation where you want to get the picture as fast as possible, just switching on and focusing before the opportunity is gone, but this does you no good at all if the settings are such that the images won’t come out decently. I suspect I get caught because I have a fairly routine collection of settings, especially for macro work, but enough situations where I deviate for particular reasons. So at the very least, give the LCD the once-over, paying attention to those little details that can trip you up – I’ll provide a short list, but this is geared more towards my own shooting style and demands, and your priorities might be different, so adjust as needed.

They’re all right there, easy to check, and you should know what each of these mean. There’s a sneaky little indicator of condition in there, too – can you spot it?

Mode: I’m usually in one of two modes for 90% of my shooting: Aperture Priority, and Manual. Virtually never in Program Auto, and I don’t think I’ve ever used the touristy modes depicted by little icons/emojis, what I call the Ducky-Horsey modes. On occasion when I switch to Shutter Priority or Bulb, however, these will mess me up unless I’m checking.

ISO: Again, most often at 250 for detail, and switching usually means I’m doing more low-light stuff. I don’t forget this often, but on occasion…

White Balance: I almost went past this one, since I virtually never change it, not liking how the camera manages it most times, but it can really shift your images if it’s wrong for conditions.

Exposure Compensation: Probably the most common one missed, both because I switch it so often and because the indicator is subtle. For many situations I’m trying to recognize what effect the subject and background are going to have on the camera’s automatic exposure setting (in Aperture Priority of course,) and will be tweaking this to try and produce the best results. Usually, it’s not more than 2/3 of a stop, which isn’t too bad, until the subject/setting really calls for going in the opposite direction. Most times when I’m caught on this, however, is when I’m switching back and forth between birds in the sky and against a darker background, like deep in the foliage or against the dark foliage reflecting off of the water. I’m usually in Canon’s Evaluative Metering, which does indeed compare the focus point against the surrounding frame and should automatically compensate for this, but too often, the subject in the focus point is much smaller than the area around it that Canon reads from, so it’s usually setting exposure for the background, i.e., the bright sky.

Custom Modes: On Canons this is ‘Picture Style,’ of which I’m usually using one of three, all set for specific lighting conditions: Normal, Low Contrast/Saturation, and High Contrast/Saturation. The latter two are set to oppose existing conditions to keep things under control, i.e., in high contrast conditions like bright sunlight, I switch to Low Contrast/Saturation to help prevent blowouts or inky-dark shadows, but will use the opposite when the light is overcast or muted.

settings on Sigma 180mm f3.5 macroLens settings: This is an insidious one, because it usually doesn’t show unless you turn the camera body to look at the lens barrel. Autofocus may be switched on or off, stabilization on or off, or the focus limiter set for something other than what you want. Stabilization is the trickiest, because you may not discover until you unload the images that it was switched off…

By the way, I will insert something here as a bonus tip. If you’re in an area where you’re switching back and forth between a general-purpose wider-angle lens, and a telephoto, it’s often a good idea to revert to the telephoto as a default, switching lenses even when the situation doesn’t immediately call for it. Here’s the reasoning: telephoto subjects like birds, deer, bears, etc. may pop up suddenly and present only a fleeting chance, not waiting around you for to do the lens change, while the wider-angle subjects, and even the macro ones, are typically less demanding that you get the shot within a few seconds or they’re gone, and will give you time to switch. It may mean more lens changes than is absolutely necessary, which does increase the odds of introducing dust into the interiors of both lens and camera body, but this habit has stood me well many times over. Ideally of course, you’d have two camera bodies and so both lenses are mounted, and you’ve at least seen photographers with two or more cameras at the ready. This is heavy and awkward, however, and I have yet to do a full session like this, especially since I can’t stand camera straps and hanging the damn things around my neck; when the long lens is mounted, camera and lens usually remain in hand, and then, where would I put them when I need the wide-angle camera? When the lens is detached, though, it gets stowed in a long lens case.

Other things to be aware of:

Metering Modes: Especially switching to Spot Metering, which is very easy to forget is in use, and it usually requires a certain presence of mind to be using in the first place.

Focus Modes: I don’t switch these often at all, but you might, and if you do, keep an eye on them.

Auto-Bracketing: There’s nothing more annoying than firing off three or more frames when you’re trying for candid or specifically-timed shots.

Menu and Custom Function Settings: In my own cases, this is most often Mirror Lock-up or higher frame rates, but things like Flash Sync mode, Flash Compensation, Noise Reduction, button assignments, and so on. Going from Mirror Lock-up to trying to track a bird flying past is seriously annoying, not to mention next to impossible as the viewfinder blacks out on the first shutter press, and while a second press will trip it as intended, you’ll have no idea where the bird is.

Arca-Swiss style quick-release plate and screwdriver on keyringQuick-release plates: This is a sneaky one if you’ve gotten used to them, and there’s nothing worse than getting someplace remote to set up on a tripod and finding out you removed the mounting plate earlier when you were using a flash bracket – this has made me not only carry an extra plate or two in the camera bag, the flash bracket now attaches to the quick release plate.

By the way, I now have a custom ‘screwdriver’ blade attached to my keyring specifically to tighten and loosen QR plates, because I rarely carry coins anymore and those little loops provided on the mounting screws are nowhere near enough to tighten a plate properly – they need to be cranked down.

What’s in the bag: If there’s something that you normally carry and you remove it for whatever reason, impress it upon your mind fiercely to put it back as soon as possible. This could be the QR plates previously mentioned, batteries, rain ponchos, your remote release, flash cords – whatever. if you’re almost anxious that you took it out in the first place, this is not a bad frame of mind to have, since such things are easy to forget and never notice until you’re on location and need them.

The Gig Check: Hoo boy, if you’re heading out on a paid assignment or a specific shooting situation, sit down and go over everything – have a list if it helps. Batteries charged, extra memory cards (or plenty of film,) all lenses in place, all accessories you might need handy, camera(s) and lenses clean and easy to access, special items added. This should also include backup equipment and contingencies for any failures, so yes, at least a second body and lenses to cover all likely focal lengths. Also, clothing you might need – I even carry spare sandals in the car when on student outings, since I had a blowout once and had to have The Girlfriend bring me another pair. Hat, sunscreen, water, parka, bear repellent, flare gun, portable helicopter – it’s easy to become overloaded, but bad if you need it and don’t have it, and if you’re under contract, this can have legal ramifications.

So, I reiterate: check those settings, and develop good habits to make it automatic. Even keep some of those frames where you didn’t, and the shot was ruined because of it, to remind yourself – it really does help. Good luck!

Did you spot that key element? It’s the aperture setting, reading “F00,” meaning a lens isn’t attached – or, in this case, a manual-focus lens not even intended for this camera, the Mamiya 80mm macro on an adapter.

Icky ones

Al DenelsbeckLeave a comment

A handful of the pics that have been accumulating over the past couple of weeks; I decided to go with the creepy ones this time around.

First, if you recall when I tackled the jagged ambush bug some time back, I placed it on a healthy cluster of butterfly bush blossoms so it could continue capturing food, since they’re reluctant (for unknown reasons) to switch away from the dead heads. That one remained on the cluster I’d relegated it to, long after it should still have been useful.

I mean, they’re well past the sell-by date, not to mention serving as absolutely no concealment whatsoever, but there it sits, visible even from a distance. Or at least, then – this was eleven days after placing it on this same cluster, which was healthy then, but eventually the ambush bug could no longer be found there, and that particular butterfly bush seems to have given up producing blossoms for the season now. Well, except for this:

sparse flower clusters of butterfly bush Buddleja davidii late in the season
For a bush that’s now notably taller than I am, and considerably wider (yeah, really,) it’s funny to see that it has but three pathetic little flower clusters like this, especially when the paler variety by the driveway, probably 1/10th the size, is still blooming enthusiastically. Ah well.

While out at night with the headlamp, it’s not uncommon to see little blue-green sparkles reflecting back at me from the eyes of spiders, but this is usually on the lawn or out on the pond surface – only occasionally do they come from plants more than a handful of centimeters off of the ground. The primary culprits are wolf spiders and fishing spiders, both wandering hunters and so spending most of their time where they can explore for their prey. Thus, when I got that little twinkle from about a meter up on a plant on the water’s edge, I had to take a look.

That’s a six-spotted fishing spider (Dolomedes triton,) but don’t bother telling me there’s ten spots, because it refers to the spots on the belly which I admit I’ve never seen nor photographed, simply because they never show their bellies willingly and I’ve never sat down to tickle one. I know, right? Slack. This was a medium-sized one, large enough to give many people the heebies but much smaller than some I’ve seen, and yes, missing a leg. They don’t, however, make a cluster of weblines suspended on plants unless they’re up to one particular thing, which you might have spotted if you’re paying attention. Here’s a better look:

adult female six-spotted fishing spider Dolomedes triton suspended on outside of web nest guarding huge cluster of newly-hatched spiderlings
Yep, that’s a brood of newborns back there, all umpteen thousand of them (I counted,) remaining safe within this tent of webbing while mom remains alert for anything disturbing it, which I endeavored not to do. And yes, I focused on the bebbies for a few frames, specifically to satisfy all those doting mothers reading.

So you know, in order to get this close, I had to be sitting on the ground right alongside the plant, which was right alongside the water, so I threw down a nylon ground cloth to try and keep my hiney dry. Except that this was right by a cluster of bald cypress knees, so doing this without pegging myself was challenging. And since the little adorables were deep within this tent, the flash was reflecting off of web strands throughout the frame, mostly defocused but still enough to throw light back and thus soften the pic. All while mom is sitting almost right underneath the tip of the lens. While I considered trying to capture an individual specimen for detailed closeups, I knew I could never get into the tent effectively without both earning the protective wrath of mom and scattering the bebbies, so I left that idea alone. I had intended to come back when daylight was striking the nest and see if I could get an angle that illuminated the young while producing as few reflections form the webbing as possible, but never tried, mostly because I strongly suspected sunlight would never actually hit the nest – mom’s smarter than that. So we have a tighter crop instead.

Still suffering from too much light scatter off of the webbing, but at least we have that one looking deep into the camera with those dreamy black eyes. No way to get an effective measurement, but I would say no more than 3mm across the leg spread.

I have no idea how long they remain in the protective nest, nor whether it’s mom or the young themselves that decide when it’s time to leave – I just checked (15 days after these pics were taken) and the nest is abandoned so, within two weeks? While individual strands of web could be found in several places on the same plant, I spotted no bebbies anywhere, and the web strands mean little – every plant in the yard likely has them, since spiders are everywhere.

Like under the kitchen window.

The telltale white scribbles in the center of the web (as well as its size, close to a meter across,) indicates that this is the web of a black-and-yellow argiope (Argiope aurantia,) commonly known by a variety of other names though I knew them by ‘garden spider.’ The shadow give more of an indication that it’s occupied, even though her legs are visible if you look closely. She moved this web to several locations in this immediate area, disappearing at least twice, which seemed odd. And eventually, we found this:

egg sac of black-and-yellow argiope Argiope aurantia tucked under eaves alongside downspout
That’s her egg sac, well-separated from the main web and also well above my head under the eaves. I’ve been eyeballing it semi-regularly, and have seen no sign of hatchlings even though it now has a distinctly deflated look; whether this is from the bebbies springing forth or the bare fact that she produced it in the steaminess of summer and now it’s considerably cooler, I don’t know. I should probably examine the bush nearby to see if I can find any sprogs – I don’t think I’ve ever photographed newborn argiopes…

Okay, that’s the creepy ones out of the way. More pleasant ones to come.

No living with me

For the last Tip Jar where I talked about making your own photographic accessories, I uploaded the design of the custom macro softbox to Thingiverse, a 3D design hosting site – I’d been meaning to do for a while but avoided it because, well, the softbox only works for one type of flash unit, long discontinued (though it’s possible the head shape is quite close to others from Canon.) I had uploaded it a few weeks previously to another hosting site, Printables, because they were having a design contest on photographic accessories – c’mon, they finally have a contest I can enter? Of course I’m there! As I type this, the contest (which ended September 14th) is still awaiting the jury…

Anyway, within 20 minutes of uploading the softbox to Thingiverse, it received a “Like,” surprising me a little because it was late at night – damn near everything I do online is late at night, because I like pretending I’m a teenager or, you know, one of those basement-dwellers. We won’t talk about where Walkabout Studios/Deep 13 is actually located…

Then a few days later, a message from the Community Relationship Manager at Thingiverse, saying I was “on the radar” for an upcoming feature and I should update my profile and bio if needed. I kind of treated this as form mail due to the new upload, and didn’t think much about it.

It was serious though, and I just got notice that the softbox is indeed featured on the Thingiverse front page. Well, cool!

screenshot from Thingiverse.com showing featured macro softbox of the author's design
Let me put this into perspective: Thingiverse has thousands, probably hundreds of thousands of users and uploaders, many of which far surpass my meager 15 designs, of which half are remixed versions of others’ work. Some of the designs are incredible, and nothing I would even remotely attempt to emulate. While I’m personally pleased with the softbox, it’s a niche design even if it was adaptable to multiple flash units, which it isn’t. So, I’m honored and a little surprised that it attracted this attention, but I’m not arguing.

Does it mean anything? Not really – more downloads of the design, perhaps some bleed over towards a few of the others, and perhaps one in 1,000 users might click through to the site here, which is indeed linked in the bio (and if you’re one of them, welcome, and thanks! There are snacks over on the aside table.) Otherwise, just a small boost to my ego, which you could determine because I’m posting about it.

Nonetheless, many thanks to the Thingiverse staff, especially Luis Cordoba, Community Relationship Manager, and to anyone and everyone who downloads any of my designs or remixes. If someone gets any benefit from them in any way, I’m pleased, and happy to help.

Anyway, back to the regular content, if anything here could be considered, “regular”…

Quite surprised to see this little spud hanging out on one of the rainbarrels this morning.

juvenile treefrog likely squirrel treefrog Dryophytes squirellus alongside rainbarrel overflow pipe
The temperatures have dropped significantly after the brutal heat of the summer, and we went to late fall quickly, especially overnight, meaning the treefrogs we’d been seeing for months vanished abruptly, and even the anoles only venture out in midday. I found this one just a little after one AM alongside the overflow pipe for the rainbarrel nearest Deep 13, while it was a whopping 5° C out there (reminding me that the Brugmansia plants should have been transferred into the greenhouse by now.) You’ll notice a dearth of markings, but I’m fairly certain this is a juvenile from the size, especially since the species that are adult at this size have distinct traits and coloration. I run into this way too often: sure, the adults have such-and-such lines or spots or whatever, but not only is there often a lot of variation among amphibian patterns and colors, they don’t fully develop these until adulthood, and no one ever seems to catalog the juvenile variations. Their calls might be listed, which only helps if they’re calling in the first place, which ever-so-rarely happens when I’m close enough to see one. Usually, the calls stop as soon as I approach.

Given all that, however, the best match that I’m finding seems to be a squirrel treefrog (Dryophytes squirellus) – if you notice, the spelling of the common name of ‘squirrel’ doesn’t match the species squirellus, just to be confusing and because, I believe I’ve said before, taxonomists are a weird bunch (and yes, I’ve double-checked the spellings.) This species should be fairly common in the area, yet I’ve only found them twice before, if that – again, variations in markings. But while I was at it, I made sure to get a clear image of the back with what could be seen of the hindlegs.

No traits there that would seem to indicate other possibilities like the pinewoods treefrog, spring peeper, or any of the chorus frogs, so I’m staying with this one. I considered setting up a terrarium to keep it within for a day or two, especially to get more detailed pics of the sides, undersides, and legs, but had largely decided against it when I found that my model here had already moved on. On the neighboring rainbarrel, however, was a juvie green treefrog of near-identical size, so either a couple of species were braving these temperatures, or my model is a master of quick-change disguises.

Anyway, a little later on I’ll get back to the stuff I’ve had waiting, before I find even more stuff to feature and/or cut in line.

Flummoxed

If you’re finding that recent posts simply aren’t loading the images, there’s a reason for that: many of them aren’t there. I am rectifying that right now, it just takes a little time.

As to why they’re not there, I can’t answer that – some weird shit’s been going down with the image folders, and it’s nothing that I’ve been doing. On the weekend I noticed that every image for the blog (there’s over 10,000 of them) had an extra ‘thumbnail’ which wasn’t very small, nor did I want it there, nor did it serve a purpose – I disabled all thumbnails, multiple times, because WordPress is notorious for making several versions of varying sizes, ostensibly to make things easier, but all it does is bloat the storage. So there should have been none, but suddenly, every folder for every month that I checked, going back years, had an additional resized image for every one that I’d uploaded.

I thought this was the fault of a plugin I had to make things load faster, which also had thumbnail creation disabled, but on occasion, plugins revert settings when updates are installed, so I simply removed said plugin. Then I began trying to determine how to get rid of the thumbnails without removing anything that I wanted to keep, and installed another plugin that was supposed to be ale to do this, but did not activate it yet. In the meantime, I backed up all (20,000+) images to my local system and tried to ensure all precautions were taken, but it got late enough at night that I was wary, and set it aside.

This ended up being until tonight, when I found that all of those extra thumbnails were now gone. What the actual goddamn fuck? I can only conclude that the host is screwing around with the image folders, especially since many of the recent images went missing – the title and specs in the Library are there, just no actual image.

So I’m re-uploading those, and meanwhile trying to determine what’s happening as well as keeping an eye on everything. I just checked, and there’s no sign of any invasive stuff, at least not in the Plugins folder, but who knows?

Eventually, when I feel comfortable that things are behaving, I’ll have some more posts, since there are quite a few images waiting – I just don’t know how long that will be.

Tip Jar 40: Do it yourself

selection of tools for modifications and repairs

Just about any photographer discovers, sooner or later, we simply don’t have some tool or device or accessory that would make our pursuits much easier. In far too many cases, this is equipment-related, as in, “I need a better camera/lens/flash unit/tripod/etc,” which may or may not be the case – in my experience, new purchases only solve the problem less than half of the time, or less than half of the problem, and I advise strongly towards a realistic examination of what any given purchase can and cannot do your you before dropping a bunch of money. But there’s also the idea that we need something esoteric, specialized, or dedicated to a single specific circumstance. On occasion, someone actually makes what we need, and if we’re lucky, it can be obtained before we need it and at a price we’re willing to pay – and truth be told, far too much of photographic equipment is priced according to, ‘what the market will bear, and then some.’ Hey, we’re all professionals pulling down big contracts, it’s worth it to us, right? Yeah, I don’t know about you…

It comes down to, the more we can create for ourselves, the less we spend and the more we accomplish, especially since we’re creating something dedicated to our specific needs. Sometimes this is easy, sometimes not so much, but what I’m saying here is, don’t hesitate to try. The amount of things I’ve adapted, modified, and outright created to assist in my pursuits is, well, presently uncountable, since I keep running across things I did years ago and have now taken for granted.

The first recommendation is, have some simple things handy, like string, tape, small clamps, wire, and some kind of knife or cutters. These allow quick application to minor issues and occasionally major ones. Gaffer’s tape is often recommended specifically because it’s strong and doesn’t leave adhesive residue on surfaces, but it’s also much more expensive than painter’s tape, which isn’t as resistant to tearing but usually works just as well in most circumstances. A small coil of monofilament is light, easy to carry, and strong as hell, not to mention often disappearing in photos, but make sure the way you store it doesn’t allow it to unroll and tangle, because it’s also the worst for disentangling.

Then there are more specific things. I mentioned last week about macro studio items, but there are also brackets and tripod accessories, many of which can be created by combining existing adapters and such items. A lot about cameras revolves around two standards: the tripod mount and the hot shoe, and having brackets and adapters that incorporate these provides flexibility when adding accessories or extensions. While the hot shoe is a specific set of dimensions that isn’t easy to describe here, “shoe mount” is the key descriptor, and plenty of adapters can be found in this way. But tripod mounts come in two distinct sizes: 1/4-20, the standard threading of most SLR and smaller cameras (and even binoculars,) and 3/8-16, the larger size used in the base of interchangeable tripod heads and on some medium-format and large-format cameras.

[What these refer to is, 1/4 inch in shaft width, 20 pitch (threads per inch), or alternately 3/8 inch with 16 pitch – this makes it easy to find matching bolts, nuts, or threaded rods at the hardware store for your own projects.]

For such adapters and many other smaller items, shopping online on discount sites such as AliExpress.com can save a ton of money, as long as you can stand the wait for shipping from China. While many decry the quality of such sources, bear in mind that most of these items from ‘major’ manufacturers are sourced from China anyway and simply rebadged, and there’s little point in paying premium prices for a few bits of aircraft aluminum with tapped holes or specifically-sized plates. It’s still possible to get poorly-made items, and the chances are likely higher from such sources – but it can also still happen when buying ‘name-brand’ too. At the same time, brands such as Neewer, Godox, and Yongnuo offer some sophisticated and much less expensive options than the name-brands, introducing the competitive price points that have been sadly lacking for decades, as well as items that have never existed before. Do what you’re comfortable with.

Being even slightly handy can expand your options as well. If you can handle drilling, shaping, and soldering, you can easily make or modify countless things to your own needs. The remote shutter release that I use came with a specific fitting for only certain Canon cameras, while others used a different fitting. Since these were all simple three-contact plugs that had the same functions, I added a stereo headphone jack and plug into the middle of the cord, and have adapters for either fitting available, able to be switched at will. Canon’s wiring is exceedingly simple: close two specific contacts to activate the ‘half-press’ focus and meter function, and all three to trip the shutter. I used my own homemade version (that’s an old page) for years until it was falling apart, and I subsequently got an intervalometer used and cheap, in which case I spliced in the jack and plug needed.

center-release lens cap with added hook tape for gripFor nearly all lens caps now, I switched to the variety with ‘center’ releases instead of edge, and added the hook portion of hook-and-loop (Velcro) fabric to the release tabs to improve grip, allowing me to reach in and affix and remove the lens cap with the hood still attached. When shooting film, I had a two-pocket pouch – one for fresh film, one for exposed, so they were never mixed up. Tripods have all been modified as needed to not only employ quick release plates, but all the same type, and the macro flash unit has the same attachment, so I rarely ever have to detach these plates from anything. It is at the point now where I literally do not take any photos without using something that I’ve done myself to improve handling or work flow.

Repairs. This is definitely a matter of what you’re comfortable with, but several of the items I presently use have been repaired when they failed, rather than obtaining a replacement. It may be complicated, or it may be a lot easier than you imagined, and typically when I tackle it, it’s a matter of “What have I got to lose?” Far too many failures stem from a loose part or a broken pin or similar and are amazingly easy to fix, and within an hour or two you may be back in business. Definitely, a precision small screwdriver set is paramount, and some fine tools like forceps/hemostats, tweezers, and modeling knives, but also the tools to open smutphone cases or anything that is ‘press-snapped’ together help. Also, lenses are a hell of a lot easier with a lens spanner. Pay strict attention to disassembly, including orientation, labeling all parts as you go (those daily pill holders or a case with bins for beads or screws can help hugely,) and take photos as needed before removing each part. Also, a small variety of safe lubricants breathes new life into many moving parts, but do a little research first. I discovered, years ago when working on model kits, that petroleum jelly degrades most plastics and causes them to crumble over time, so using silicone-, lithium-, or even lanolin-based lubricants is much better. Do not clean painted surfaces such as lens markings with alcohol – it can degrade the inks/paints used.

3D printing. Okay, listen, I would never recommend buying a printer and learning how to design parts – and I would never recommend against it, either. The learning curve is steep, especially in making your own designs, but even just the quirks and tweaks of a basic filament printer can require a lot of time to get through. All that said, the number of things I’ve done with one is astounding, and not just for photographic items either. If you are into model kits, crafts, wood or metal working, disassembly, repairs, or anything of a similar nature, you may well find that possessing a 3D printer is a huge boon and not that hard to figure out (plus the online resources for learning and problems is vast.) Not to mention, how high the chances are that someone has faced the exact same challenges that you are and have already created and uploaded a design, so all you have to do is print it. This is definitely an option that, once you have it, you realize how much can be done with it. This page features some of the strictly-photographic designs I’ve worked on and uploaded – or this one has the complete collection (with non-photographic schtuff included.)

Just so you know, I have been trained, educated, or have working experience in none of this – my dad taught me nothing, I had only a partial semester of metal shop in high school (so long ago that I don’t think alloys had been invented yet,) none of my jobs required anything of the sort. It is 100% self-taught, and the best I can say is I got started on model kits at an early age. Some things you learn by doing, so don’t hesitate to try something on your own. Chances are it won’t be perfect at first, but stay with it and it will.

Good luck!

Stomping Grounds: The fartsy portraits

Al DenelsbeckLeave a comment

great egret Ardea alba and great blue heron Ardea herodias standing close together in shallows of Jordan Lake
We’re back to the Jordan Lake session again, but this time we’re going for the high art angle, better than A through E art, and frame-worthy portraits to boot. Get out your checkbook! And do a websearch to find out what a ‘checkbook’ is…

It’s gonna be a little heron-heavy, since that’s what was most present that day, but hey – herons are majestic birds anyway, as long as you can’t hear them. That’s why the focus above is clearly on the great blue heron (Areda herodias,) which also helps distinguish the gap between it and the great egret (Ardea alba) that was much closer.

Also hanging out were the double-crested cormorants (Nannopterum auritum,) but they were showing little in the way of majesty so they’re just background elements here.

It seems casual and simple, but with the working distance and the entire lake to fish within, catching all three together in nice framing was much more a matter of timing, since within two seconds this looked entirely different, and within a few more, none of them would be in the same frame as another. Trains passing in the night, uh, late afternoon…

By the way, while the water level was down significantly to be showing these rocks in the shallows, it’s not the lowest we’ve seen it; if you go to this post and scroll down to the sleeping cormorant, I’m pretty certain the rock it’s snoozing on is the same one making an appearance here.

Even narrower timing was this:

Okay, i admit it – there was a dash of luck involved, but I was tracking the egret, and consider it more lucky that the autofocus stayed locked on tack sharp on the egret while panning. Still, I find this spacing more than acceptable.

As the previous post showed, there were a couple of other species, but really, not many. This osprey (Pandion haliaetus) was one of them.

osprey Pandion haliaetus cruising overhead
Even with the lower angle of the late afternoon sun, this could have been lit better, getting the undersides more, but at least it came through on the eye, and that’s what we look for most. Unless we’re weird. Nice spread on those tip feathers though.

It’s funny – it wasn’t all that long ago that we never saw any bald eagles (Haliaeetus leucocephalus) at Jordan Lake, and even though they were nesting at another lake several kilometers off, I’d never even seen one there either. Now, it seems like something’s wrong if we fail to see at least one for any given trip. This afternoon had been so quiet that I was resigned to the possibility, but then one passed by straight overhead and at least kept up standards.

second-year juvenile bald eagle Haliaeetus leucocephalus approaching, eyes on photographer
This is a tight crop of a still-pretty-distant juvenile, the first frame obtained, but it shows the eagle was at least aware of us as it approached. This did nothing to alter its path or behavior, and it flew right overhead, intent on some other task.

second-year juvenile bald eagle Haliaeetus leucocephalus passing directly overhead showing plumage clearly
Between the two frames, there’s enough to determine that this is a second-year juvenile; this year’s brood would be almost entirely brown with perhaps faint flecks on the wings, while a third-year would have noticeable white along the sides of the head, and from four years on, they appear as everyone knows them, white head and tail but otherwise deep brown. Now, why they have such distinctive and different plumage through their first three years, I can’t say. I could understand the youngest being dark and blending into the shadows while perched and awaiting food, even though once they leave the nest they’re only fractionally (if at all) smaller than a full adult so, you know, not vulnerable to a hell of a lot. What the mottling does, I have no idea, but the white head and tail don’t seem to serve a purpose either, though it does distinguish them from golden eagles and ospreys, even at a great distance, so perhaps this is why? I’m just spitballin’…

Yet another heron – this one probably could have gone into the behavior post…

great blue heron Ardea herodias flying so low over the water its wingtips are touching the surface
Herons clearly take some effort to gain altitude and rarely attempt it, often staying just barely high enough above the water, and this displays how barely: its wingtips are touching on the downstroke. You can also see why we work this spot in the afternoon, since it faces east and thus the westering sun provides good light. It had rained overnight, in fact, and it was touch-and-go as to whether the clouds would clear enough for a decent session, so this is pretty good really.

Some songbirds were active in the trees on the lakeshore, in some cases disputing territory, like this brown-headed nuthatch (Sitta pusilla):

brown-headed nuthatch Sitta pusilla on trunk with head raised
As arrogant and disdainful as it appears here, it was paying little attention to me and far more to the chickadees flitting around nearby, to which it seemed to take exception. Nuthatches never struck me as being aggressive or territorial, but then again, I don’t think I’ve ever watched them long enough, or seen them near other species much at all.

Rustling in a forked trunk not far overhead led us to this one, who watched our approach with trepidation:

eastern grey squirrel Sciurus carolinensis appearing to be making an autumn nest rather low in a tree
That’s an eastern grey squirrel (Sciurus carolinensis) peeking out, that drew down out of sight and held still once we stepped just a little closer than this. Squirrels can make noise all out of proportion to their size, which is odd because everything preys on them, and this one appeared to be making a nest; this is not too odd, since at this latitude, grey squirrels often breed in both the spring and the fall.

Getting seriously fartsy with this one, while also chronicling some details:

fallen trunk on lakeshore pointing towards tempestuous clouds
This shows the quality of the sky and why we were lucky to have the light that we did, though this is faintly later, on another arm of the lake about a kilometer away. It also shows a fallen trunk that, when upright, had served as a perch and setting for numerous photos appearing here, among them the bored eagle in this post. Not too long ago this dead tree had finally given up the ghost, and I wanted to capture it here before the winter storms and water levels carried it off.

[Funny, that linked post noted another trunk that we’d been very familiar with that had fallen not long before…]

Two more to close it up, both similar – it’s up to you to pick which one works best, but they both show off the cloud conditions as a nice backdrop texture. So do you like this one?

great blue heron Ardea herodias banking against cumulus clouds
Or this one?

great blue heron with wings on downbeat against cumulus clouds
Only one of which is correct, so take your time and don’t screw it up.

That closes out the Jordan Lake photos – now I just have to get to the local shots that have been piling up. A blogger’s self-imposed workload is never done. Until they quit, anyway.
