A batch of autumnal monochroma

Al Denelsbeck

“Wait, monochrome?” you say, “As in, black and white? Al, you fucking moron, fall is the time to exploit the colors, not eliminate them entirely. What, are you trying to be avant-garde or poetically ironic or something equally spastic?”

Which hurts, I admit it, even when I wrote it myself. But I saw the possibilities of some of these, which worked better than most of what I’ve shot in the past several months for converting, so here we are. Now try to be nice.

time exposure of backyard by moonlight, reduced to only red channel monochrome
By converting this one, it almost says “moonlight” better than the original. This is channel clipping again, just the Red channel. If you haven’t tried this, you should – some pics just look blasé, while others pop up with something entirely new.

fraternal potter wasp Eumenes fraternus on chrysanthemum blossom, reduced to only Blue channel
This one wasn’t part of the original lineup, but as I was doing these, I went back through recent pics for some candidates. Most of them didn’t work that well, but this one converted nicely, using only the Blue channel this time; most times Blue is the least interesting, often grainy, but it brought out the mauve chrysanthemum blossom well. The fraternal potter wasp (Eumenes fraternus) was already monochrome anyway.

An insert here, two that have been sitting in my folder for nearly a year – I just never posted them. But this is a view of The Bayou in winter, taken from the best vantage that I could reach by foot (so far, anyway):

view of The Bayou in winter, reduced to only the Blue channel
Just the Blue channel again. I could have tweaked contrast to improve this one, but there was a reason that I didn’t, which is, this is the full color version:

view of The Bayou during winter, nearly monochrome by itself
The cypress had all shed their needles, and the Spanish moss never has much color anyway, and facing south (my only choice) made the sky more washed out. In fact, I think it had more color than it might have because that’s ice you’re seeing, reflecting the sky color even better. What I should do is convert the two images into an animated gif (pronounced, “JREY-skayl“) that slowly morphs between the two, and say nothing about it, just to make people think their vision is going wonky.

Carolina anole Anolis carolinensis overexposed, converted to greyscale
This one, from October’s month-end abstracts, is simply a conversion to greyscale – I tried channel clipping, but each of them left something to be desired. I like how the eye almost produces a pure black and thus suggests the exposure was close to proper anyway, while the rest is a light pencil sketch. Very avant-garde.

backlit bald cypress needles reduced to only the Green channel
The Green channel this time. Funny thing about this one: I had an original cropping for the color version all set to go, but then when I converted to greyscale, I realized it looked better with a slightly different crop – and so did the color version, so that’s what I ended up using. Hilarious, right?

scattered leaves on surface of water with high contrast by reflection, combined Green and Blue channel greyscale
I remarked on the high contrast of this one despite the low contrast lighting conditions, and this is what prompted the monochrome experiments in the first place. This is one of those minor refinements, in that it’s a combination of the Green and Blue channels, making the Green (which sits ‘above’ the Blue) transparent to a degree – either one by themselves wasn’t quite right. Now it’s even more surreal and seems far more like elaborate digital editing, which might work against it standing alone – we know what the color version looks like, so we know it’s just a trick of the light and surface tension, but without that it may seem too artificial. Still, I like the eye-bending aspect of it.

And finally,

dew-covered Carolina anole closeup reduced to only Blue channel monochrome
I did this one some time back, soon after the original posted, but had nothing else to go with it, and just remembered it now. For saying that the Blue channel is often a poor choice, here it is again – we’ve actually had more of these in this batch than the other channels, so maybe don’t listen to me. I know, “Way ahead of you, Al,” shut up. But seriously, go do your own experiments, see what you produce – it’s healthy and appealing to the appropriate sex, and how many things can claim that nowadays?

Comparing the mics

Al Denelsbeck

Last night we had a thunderstorm roll through with some halfway decent thunder production, and I grabbed the two wildlife microphones to do some recording and comparisons. This turned out to be a great test subject, because it demonstrated just how different the methods captured sound.

The first microphone is the newest addition, though I’ve had the main part for a while: a Sony ECM-44B lavalier mic, but fitted to a 3D-printed parabolic dish to focus and magnify sound (I’ve reprinted it since that post, so it’s slightly improved now.) Initial tests with this showed that it was excellent at being able to pinpoint a sound source by the changes in volume as it reached the focal direction. But the smaller the parabolic dish is, the more low-frequency sounds it fails to capture; ideally, it should be in the realm of a meter across, but that’s unwieldy in just about any application, and commercial designs seem to fall a little less than a half-meter. Mine, however, is 26cm across the widest section, limited by the size of the printer bed.

The second microphone has been in use for a while now, an Azden SGM-2X unidirectional ‘shotgun’ mic intended for exactly these kind of uses, fitted with only a ‘dead cat’ wind guard. Shotgun mics are really slick in how they reduce off-axis sounds, and I don’t want to go into it here but encourage you to look it up if you’re unfamiliar with it, because it’s great.

Both mics have their own power source, a single AA battery, and both were feeding into an Olympus VN-8100PC digital audio recorder. Both were also pointed in the same general direction from the same location on the front step, about 30° upwards over the tops of the nearby trees where I could see the flashes and occasional lightning bolt, and by this time it was raining steadily, as can be heard. Unfortunately, I couldn’t do a direct side-by-side comparison since I only had the one recorder, so I could only pick thunder examples that seemed roughly the same, so precise it’s not. That said, the audio recordings showed a drastic difference in tone.

First, the parabolic dish mic:

Parabolic dish mic test

I had amplified this one slightly to get the ambient rain sound in the same general realm for both recordings, so the thunder could be more directly compared, and I let the recording run until I could no longer make out the echoes of the thunder.

Followed by the shotgun mic test:

Shotgun mic test

That’s a world of difference – the parabolic dish really doesn’t capture the lower registers well at all, though I think the shotgun mic is both optimized for them and has more of a built-in pre-amplifier. It also has a ‘low pass filter,’ which can reduce much of the very low frequencies/longer wavelengths, since a lot of ambient noise falls into this category. However, I was not using this setting since I wanted to see how low it captured.

Another example from the shotgun mic, this time of the loudest thunder that I heard while out there. Listen carefully, because you’ll hear the rain vanish for a few moments:

Thunder through shotgun mic

I actually heard the rain seem to stop through the monitoring headphones, amusing because I was standing right there and knew that it hadn’t, and I was a little concerned that the audio had issues. But what I suspect now is the Olympus recorder has an auto-levels setting and it quashed the volume as it began to creep too high, resulting in the quieter rain dropping off.

I also have to mention that I stepped out into the rain with the parabolic dish, and this is not recommended: the thin plastic of the dish picks up the raindrops hitting it all too well, producing a tinny but distinct tapping sound, close to the sound of rain on tight sheet plastic (which I guess it is.) Meanwhile, the dead cat on the shotgun mic prevents nearly all noise from rain hitting the mic, though you can still here faint taps when it hits the mic body outside of the wind guard. And both, of course, need to be handled gently with as few hand movements as possible, since these transmit through the bodies and come out quite distinctly in the recordings.

But I think the answer is clear, and I’ll be staying with the shotgun mic for audio and video recording, though I intend to do some tests with the wood ducks, notably much higher in pitch, to see if the parabolic mic amplifies those better. I think it’s likely that the parabolic will be used mostly to locate subjects with precision, because it is good at that, while the useful recording will be with the shotgun mic.

[I just have to add that I have a lightning tracking app on my smutphone, and I purposefully changed the alert tone to an actual recording of thunder that I’d made some years ago – which went off while I was listening to the audio of this very post in draft form. Nice little surround-sound effect…]

Next batch of autumnal chroma

Al Denelsbeck

“Autumnal” – that’s where Radar O’Reilly is from, isn’t it?

Now on to part two of the recent fall color pics, most of them from right here at Walkabout Estates Plus, but a few from a downtown park. Like this one:

unidentified tree producing backlit autumn colors against blue sky
We actually saw this same tree last time – this is just a different spot on it. Making sure to use the backlighting, of course.

Canada geese Branta canadensis in backyard pond under variety of autumn colors
The light wasn’t the best, the colors not exactly popping, but convincing the geese to come back at a better time wasn’t going to happen – and I didn’t tweak this one for more saturation this time, either. Perhaps I should’ve…

I remarked earlier that the bald cypress in the immediate vicinity all had different schedules for changing. We have this one, hanging on in places:

bald cypress Taxodium distichum with green patches among the fall foliage change
… and then this one, completely given over to the orange side:

bald cypress Taxodium distichum completely turned to red-orange in fall
… and why there’s such a difference, I couldn’t say (without a decent contract.) It’s not like there’s any significant change in the conditions, or their distance from the pond. The best I can say is that, due to the open area of lawn (I use that word loosely) alongside this one, it receives more direct sunlight than the others which are clustered together, so maybe that’s it.

We can’t neglect our leaves on the water, a perennial favorite of mine:

variety of fallen leaves and duckweed on small channel of backyard pond
I made it a point to choose an angle that caught the sky and neighboring tree trunks reflecting from the water, brightening the frame considerably more than the typical dark water background. And selected that red leaf of course, but there aren’t enough maple trees in the area to provide sufficient fallen red leaves. We are at least trying to remedy that with the Japanese maples that we planted, but they’re all pretty small right now so their contributions are minimal – give it a few years. Though this one is trying:

changing colors of coral bark Japanese maple Acer palmatum 'Sango kaku' on same branch
Yes, we saw this same coral bark Japanese maple (Acer palmatum ‘Sango kaku’) before, and we’ll see some of the leaves again as a setting in a post or two, but I just like the way the colors change so abruptly on the same branch, and this tree isn’t even as tall as I am, having maybe a half dozen branches – we just got it this summer, and transplanted it less than a month ago. I may also be back to feature another, whose autumn changes made me wish I’d set up to do a time lapse.

yellow fall color of probable grapevine backlit against blue sky
C’mon, clear blue skies and backlit yellow leaves? You always have to try and make those work, even when you have a bare quartet of leaves to work with (I think this is a grape vine.)

Now, the same night that I did the ‘supermoon’ pics, I also did some time exposures by the light of said moon, and we’re going to see four of them, spaced out a little. This is the first:

time exposure of upper end of backyard pond under light of full moon
81 seconds, f5.6, ISO 800 – you can see some streaks from the stars, and they’re only as short as this because this was facing north-northeast. But I also did a variation of this perspective in daytime, albeit when the sun vanished behind a cloud:

wood duck nest box over backyard pond under fall colors
Another look at the wood duck nest box, patiently awaiting its use in early spring. See that trunk just barely peeking in the frame to the right? That’s the same as in the image above it, the most distinct one a little right of center – the moon wasn’t reaching the nest box at that time, unfortunately.

time exposure under full moon of backyard pond, fall colors, and Turtle Island
That’s Turtle Island in the center there, which appears to be in the center of a well-trimmed lawn because of the duckweed, but that is indeed water. This is about a dozen meters to the right of the previous night exposure, on the bend on the pond.

cluster of backlit possible maple leaves in fall colors
Another from the park – maple? Not sure. I selected the leaf at bottom as the focal point because it’s relatively unobscured and unshadowed, and made sure the focus brought out the veins.

Back to Walkabout Estates at night:

time exposure of stretch of back yard of Walkabout Estates Plus under moonlight
A similar shot, also under moonlight, was featured a month ago – last full moon, of course – but without much of the autumn coloration then. Once again, a little assistance was provided by the streelight that sits at the head of the driveway, coming in from the right around the end of the house. Though it’s not terribly visible, the thicket to the right is actually the foliage within The Puddle, a damp hollow that’s sometimes a tiny pond, and sometimes just squishy – it’s closer to pond right now.

Back to daylight.

branch of bald cypress Taxodium distichum showing fall color variations among the needles
Another branch of the bald cypress right in mid-change, caught as a shaft of sunlight worked its way through the canopy, making it glow. We’ll see another variation of this later on.

Back to moonlight.

time exposure of pond in backyard of Walkabout Estates Plus under light of full moon
We saw this same perspective a month ago, too, even with the same strand of Spanish moss, but without the schmuck this time. That’s Duck Island left of center, four different species of tree sprouting from one little tussock that isn’t even above water right now. I like how the moonlight rendered this (84 seconds, f5.6, ISO 800.)

And finally, back to daylight, kinda,

collection of fallen leaves on water surface with reflected hazy sky
I’ve done a variation of this long ago, with the fallen leaves and the reflection of bare branches in the water surrounding them, but this time it’s more mocking with full foliage in the reflection. While the light is distinctly low-contrast and the colors all quite muted, the image nevertheless has high contrast from the water reflecting the sky and the leaf shadows, with the surface tension rimming much of the detail in stark outlines – I like how this came out, half-unintentionally, and you’ll see a variant of it soon.

That clears out the autumn colors that I’d had in the folder, which is not to say that some more won’t be along, but this is the best showing that I’ve had in years, I think. Without making any special trips, either. One of these days, we’ll get a mountain trip timed right, though we’re now at least five hours from the mountains. Too late for it this year, but there’s still time to find a few more selections of foliage in this area, so we’ll see what transpires.

I am not to blame

Al Denelsbeck

Listen – we haven’t seen a single bunny rabbit in the yard since we moved here. There have been a handful of fawns, and you’ve seen them all. No lambs, no kittens, certainly no red pandas or meerkats or bushbabies or quokkas. Assuredly, if there were, I’d be photographing them, but I can only snag what I see, and the cute ones are few and far between. It’s not my doing.

The other night when the supermoon was stunning the entire world, for some reason, the wolf spiders were heavily in evidence, emphasis on the ‘heavily.’ Spotting the eyes in the headlamp, I sidled up to the largest wolf spider I’ve ever seen – and then another, and another. Within four minutes I’d found four monsters, three of comparable size and one just a wee bit smaller. Between the moonlight and the nice temperature, I’m guessing they were taking advantage of prime hunting conditions, but that’s only a guess. We’ll start with one in its habitat.

massive unidentified wolf spider Lycosidae at mouth of its burrow in the reservoir of a planter pot
Since the eyes reflect extremely well, little blue-green stars within the grasses, I was able to spot them all from several meters off and stalk them, two of which were standing guard just outside their burrows. The ‘burrow’ of this one, however, was actually the reservoir of a planter pot, one that I’ve had for years and first appearing here. The spider (I’m presuming) had used leaves and grasses to fashion more of a restricted opening just its size. There’s too little for scale here; for that, we go to the first that I found, and caught for the studio shots.

massive adult female unidentified wolf spider Lycosidae with US quarter for scale
Capturing this one was remarkably easy, just scooting her into a small tub, and she also behaved well in the shallow dish I use for such sessions even though she could probably have stepped out without scraping her belly. That’s a quarter in the dish with her. I’m not even attempting to determine the species, since there are “Approx. 240 species in 21 genera in North America north of Mexico,” according to BugGuide.net, so we’re just going with Family Lycosidae. To her credit, this one moved very little in the dish and allowed me some closeups.

massive unidentified adult female wolf spider Lycosidae in closeup
I cropped this one a little too tight to see, but the pedipalps are narrow and pointed, signifying a female, though the size is probably enough; for most spider species, the females are the bulkiest to have the nourishment to produce a few hundred eggs, while the males are leaner and often magnitudes smaller. What are the chances that these can still produce an egg sac before winter? I can’t say, but I’ve been surprised by how cold hardy spiders can be, popping out after a freeze that I would have thought would kill them.

The Sigma 180mm macro and the custom softbox brought out a curious detail that we’re going to go in even closer to see. You’ve made it this far, you’re good.

closeup of eyes of massive adult female unidentified wolf spider Lycosidae
Think she’s fearsome? Look at those eyes – she’s terrified, and only wants a hug! Though what we’re actually seeing here is the reflection of the walls of the small dish that she was resting within, combined with the angle of the softbox light source for those white spots. But it’s a good illustration of the Lycosidae eye pattern, one of the better ways to distinguish spiders: four low in front, two main eyes centered above, and two side-facing eyes higher up and almost on the sides of the cephalothorax (‘head/body’.) The fishing spiders, which can get bigger than this, have those last two eyes more in a horizontal line with the two main ones, even when they can appear almost identical to some of the wolf species.

I soon released this one without ever having to try and recapture it within my bathroom ‘studio,’ but made several attempts to snag another near her burrow, to no avail – she always ducked back down before I got close enough for a decent frame. Which was probably for the better, because just over a meter away, this little spud was lying in wait:

eastern spadefoot Scaphiopus holbrookii out hunting by moonlight
That’s an eastern spadefoot (Scaphiopus holbrookii,) a toad large enough to make a meal out of wolf spiders even this large, and whether it knew the spider was about or not, I can’t offer any opinion. I know that when we established a little pond liner in the back yard of the old place, the green frogs wasted little time in moving in, and soon afterward, not a single wolf spider could be found in the back yard, though the front yard still had plenty. Even a few fishing spiders set up residence in the pond, but never for very long.

By the way, this is still late at night, but shot with the custom softbox – I can’t complain about its lighting ability.

Two days later I was out around the upper pond edge and went to step between a couple of saplings, only to be pushed back by what I thought was a twig. It wasn’t – it was a web, which I discovered almost simultaneously with finding this one a little too close to my ear:

adult female golden silk orbweaver Trichonephila clavipes very late in the year
Nothing for scale here either, but the leg span of this golden silk orbweaver (Trichonephila clavipes) would have come close to covering my palm, and while I’m probably exaggerating in memory, the abdomen wasn’t far from the size of my thumb – I’ll get some specific measurements later. [EDIT: I did. Not quite the size of my thumb, but very close to the top two joints of my little finger, a body length of 35mm. The leg spread account was accurate, though.] This one was a surprise though; the property had been littered with them several weeks back, but they rapidly disappeared as soon as the temperature dropped just a bit overnight. While possibly from the cold, it’s more likely that they had passed the laying stage and thus fulfilled their life cycles, living only a year. I have yet to find any of the newborns, or even an egg sac (old or current,) so I can’t vouch for how successful any of them were in reproducing, but this one was still game, it seems.

I have to stress how much resistance the web gave as I tried to pass through it: it’s not exactly fishing line or thread but it feels like it, remarkably tough, and I didn’t actually break through it before I backed off to see what I was missing. I could possibly have ended up as another meal for the spider had I been a little less alert, but then again, had that happened we wouldn’t even have this post, would we? I’ll let you stew on that…

First batch of autumnal chroma

Al Denelsbeck

Boy, do we have a gout of photos to get through now! They’re going to be spaced out a bit, so perhaps they’ll last the week, but a few days at the least. And that still doesn’t count some (a lot of) video clips to edit together. So let’s get started.

This year we have a decent selection of fall colors, almost all of them local – and this was after I was concerned that we wouldn’t have many at all. The summer was hot and dry, which is rarely a good condition for the trees to turn brilliant, but right before the crucial point we got some heavy rains, and that might have done the trick. However, nearly everything that I have is a vertical composition – we’ll just have to cope.

autumn pin oak leaves blowing past nearly bare branches of American tulip
This was actually earlier today, and the weakest one that I have (“Strong start, strong finish, Al,” yeah. hush,) but the conditions sprung up as I was there and I snagged a couple of quick frames. While the leaves are from a pin oak, that’s out of the frame, and the branches are the American tulip tree that had dropped nearly all of its leaves during the drought anyway.

collection of fallen leaves in shallows of pond
The pond contributed to making a collection of fallen leaves three-dimensional, even when there wasn’t a lot of color to be had right there. But we have some photobombers…

inset of previous images showing minnows floating over leaf
Now that the duckweed is breaking up and not shielding the entire water surface, some of the pond denizens become visible, enhancing the depth aspect a hair.

This one was re-shot today, because the original didn’t quite have the lighting that I wanted:

view of pond with fall colors and basking turtles
Ehhh, okay, but not great, and the basking turtles that I wanted to be well-lit still don’t show up in the wider angle necessary to get the most color in there. We’ll see a variation of this in a later post, but right now, we’ll see another variation that I never intended but stumbled across while exploring, also today:

turtles basking on tiny island under brilliant yellow autumn leaves
Same island, almost directly opposite – these leaves were shielded from view by the trees on the island itself. Also, this approach helps disguise the bare fact that most fall leaves look pretty tattered, and finding clean, photogenic ones can be a chore. This is demonstrated by the next composition:

backlit autumn leaves, possibly maple, showing rough shape
This wasn’t on the property, or today, but the backlit colors popped up nicely while the leaves themselves looked like plague survivors from last century. That’s a nice mental image to provoke for the gallery, I’m sure…

But these are better:

cleaner fall leaves of unknown species backlit on tree
I can’t be bothered to find out what species of tree this is – you want this to take forever? – but they look healthy at least. Or as healthy as leaves that are rotting away on the tree before falling and decaying to dust can possibly look. Which is pretty good, really.

coral bark Japanese maple showing two distinct colors for fall
One of the new Japanese maples, recently transplanted, is a spindly little thing right now yet produced the best autumn colors of them all – these leaves on on the same branch, the ones on the end changing to red first, and not too gradually either. You’ll see this tree again later on.

color-enhanced view of entire tree in autumn against clear blue sky
I admit to cheating with this one, since the image came up much more lackluster than it looked in person – I probably should have been bracketing the exposure, and this has showed in several other compositions as well. So I took the best and boosted saturation a little, getting a bit closer to what I was actually seeing, though this might be a tad too far. Still, it’s not overwhelming, and it’s not AI, simply Al.

And to close out today’s batch:

branch of bald cypress tree showing mix of autumn colors
The bald cypress trees outnumber everything else (save for the bamboo) on the property, and show such a wide variation of colors for trees only a few meters apart. Are these leaves, or needles, or what? Regardless, you can see them turning from the tips inwards, and I liked this composition for the stark curving branches cutting through the colors – cypress branches are often curved, oddly.

That clears out a few, but not all of them and not the best – and who knows if I’ll snag some more in the interim? Don’t touch that dial!

[Go ask your grandfather what that means…]

Estate Find XLV

Al Denelsbeck

We hope you’ll join us in welcoming back our old friends – unless of course they’re not actually our old friends, in which case we welcome some new ones, even when they’re not as friendly.

As I said in the video, the Canada geese (Branta canadensis) have been missing from the environs since May – the last time they appeared was to bring by their new brood (or complain about it,) and then they simply stopped showing up. Parenthood, I guess.

Canada goose Branta canadensis returning to backyard pond
This was about the time last year that we first started seeing them, though, so perhaps it’s their normal schedule. They showed no recognition of us, so we’re thinking these are a different flock than the ones coming by earlier in the year.

[We’d semi-habituated the earlier ones by offering corn, and they took to this quickly, coming up close for handouts. The ones that appeared this week show no inclination, and made their way further off across the water as we approached the pond edge. A couple of them seemed to pause and pay attention when the corn started pattering on the ground, though, so maybe this might be only a matter of time.]

trio of Canada geese Branta canadensis remaining wary at approach of photographer
By the way, I mis-spoke in the video when I said the patch of sunlight was coming at late afternoon. It was actually early morning, and facing largely east, but the sunlight was a patch reflecting off of the storm door on the porch, I think. I knew this, but in handling umpteen different video clips I forgot which one I was using. More are coming, too. Meanwhile, go back and watch around the 3:42 mark in the video for one goose to ‘goose’ another right in the ass to get it to move on a little.

With the weather getting crisper, the wood ducks have changed their habits too, being out more into the sunlight a bit and hanging around longer, but they’re still largely morning and early evening visitors. The geese, however, come later in the morning most days and may be back and forth all day long, being seen the most in late morning and typically just hanging out on the pond as if bored.

five Canada geese Branta canadensis almost lined up as they drift off
Now, I’ve spoken before about doing most of the pond shots from the upstairs bathroom window, because it has a pretty good vantage and is fairly subtle, though at times I suspect the wood ducks have seen me up there. For a while, I couldn’t even do any photography if I hadn’t have opened the window before they arrived, because they heard and saw it opening and took flight. This is their rough perspective:

view of back of Stately Walkabout Manor from the perspective of anything on the pond
The bathroom window in question is the dormer to the right of the chimney so, you know, this is not exactly an obvious threat. I enlisted The Girlfriend’s help in getting some pics from down at the pond edge to see just what the ducks could see, and it’s far less than I thought.

view of bathroom window with author behind camera within
From having seen the ducks get spooked right as I was adjusting the zoom, twice, I thought they could see my arm moving. But what can you see here? Okay, let’s brighten it up a little (lot.)

view of bathroom window, lightened to show author within at camera, by The Girlfriend
This is the exact same image as above, just brightened considerably, and you can just make out my arm, the lens, and the microphone (and my mug of course.) I’m considerably less convinced that the ducks could see a damn thing. And no, there are almost no occasions when the light is coming directly into the window – most times the ducks are too early for the sun to break through the trees, and in the evening the sun is well behind this spot. There have been just two occasions when the sun was illuminating me in there, and I was careful not to move more than a hair. We’ve also seen the ducks spook over nothing apparent at all, and as I said, their average time scarfing corn is less than 100 seconds before they scatter, invariably, so it almost seems they have a ‘hazard limit’ to how long they’ll be onshore.

Now, the change to shooting position:

view of back side of Stately Walkabout Manor with lattice removed from under deck
See the difference? It’s the patch of missing latticework from underneath the deck, which permits roughly a 30% closer vantage than the bathroom window, and if you look closely, you can see the silvery leg of the tripod in there, at least in this light, though this was taken much earlier than I was attempting to shoot; this was taken aiming close to due west, the sun being almost directly to the left, and by the time I was doing the initial tests the sun had moved a few hours onward, more behind the house. Near as I could tell, the goose and the wood ducks could still see me in there; I wanted to be further back and deeper in shadow, but the narrow gap meant I would restrict the field of view more by doing so. Part of the reason I was doing this was to open up the view, most especially of Duck Island which is normally obscured by the trunk on the right here; the other reason was to get closer without spooking the critters. Anything else would require a complete blind to be set up, and then I’d have to be in place well before anything showed because I wouldn’t be ale to get to it unseen. This spot is bad enough: getting into it (from the right side, behind the chairs and camellia bush) is still tricky and fraught with the possibility of spooking the ducks, plus it’s hell on my back since the space is less than 150cm. Just bare earth down there, no room for even a stool, and I’d have to remain for an hour or so. I’ll probably just stick to the bathroom.

Rush out there now!

Al Denelsbeck

Or, don’t – I’m about to show you why not.

So, once again the media is hyping a ‘supermoon’ for the full moon going on right now, which means a full moon very near the moon’s closest approach to the earth, or perigee. “The biggest and brightest moon for all of 2025!” or even longer periods, and such articles pop up all the time. We have a very clear night out there right now, and the moon is indeed bright.

second-quarter 'full' moon very close to perigee, 'super moon'
Of course, I could mess with the exposure and make it look far brighter, or far dimmer, so this means nothing. And while this is at 600mm, it’s also cropped quite a bit from the original, which looked this big in the frame:

second-quarter 'full' moon very close to perigee, 'super moon,' full-frame
But, you ask, how does it compare to a regular moon, or perhaps the farthest and smallest moon in the sky? And I’m prepared for that one, since I overlaid another exposure, same focal length, but very close to the moon at apogee, the farthest from earth, so we can see the overwhelming and drastic change in size for this magnificent event:

second-quarter 'full' moon very close to perigee, 'super moon,' overlaid with same phase very close to apogee
That’s it – that’s very close to the biggest difference in sizes possible from the moon in the sky. Specifically, it’s tonight’s moon at a distance of roughly 351,500 km, versus the full moon of March 24/25th, 2024, at a distance of 400,900 km. The orbit is elliptical, but not that elliptical.

[This was a mere two weeks before the total solar eclipse of that year, by the way, which always happens during new moon.]

second-quarter 'full' moon very close to perigee, 'super moon,' overlaid with same phase very close to apogee, roughly the size they would appear to the naked eyeIt gets a lot worse when we see the approximate size that it appears to our eyes, like this – it’s as close as I can get since everyone’s monitor resolution is different, and some people even view websites on their smutphones, believe it or not. Seriously. But if you want accuracy, back off from the any of these images until you can just cover the moons with the tip of your pinky held at arm’s length. Then you can compare the drastic difference in size between a ‘supermoon’ and a ‘patheticmoon’ or whatever you want to call it.

Now, while out there tonight, I did do several exposures by the light of this supermoon, as well as chasing a few other subjects, but they’ll be along in a separate post. I wanted to get this one up in a timely manner to save you the huge disappointment in discovering that the media is hyping something all out of proportion.

It’ll taper off

Al Denelsbeck

I’m in a rut and I know it – there’s not a lot I can do about it, but there’s content at least, by a real human being too. Soon enough, these subjects won’t be visible for a while. I think.

First though, we revisit the end of month abstract – one of them, anyway. On the night that a persistent mist hung in the air, making the headlamp appear to be shining through a mini snowstorm, I caught some distinct bright spots on the yard and went in for the photo, so the overall frame looked like this:

This is a fallen leaf of the American tulip tree (Liriodendron tulipifera) in the back yard, the underside catching the mist but also repelling it somewhat so the water stayed in tight droplets, and from a short distance, these water drops set the leaf glowing in the headlamp. Once back inside and unloading the memory card, I liked the effect and the detail and did a tight crop of a section at lower center. Then I wondered if I could do it better by going in closer, and so went back outside to tackle the leaf again. Except, closer did not actually help it:

Not bad, but being closer meant the softboxed flash produced a different light effect from the drops, and I liked the original (shot at a greater distance) better – the drops were better defined. It’s funny how the change in lighting worked.

Okay, now back into the rut, since while I was out there, I was also doing still more photos of the Carolina anoles (Anolis carolinensis,) partially because they had re-emerged to sleep on the branches again with the temporary rise in overnight temperatures, but mostly because the mist added a lot to them. Soon enough they’ll be in for the winter, or at least only peeking out when the sun brings the temperature back into an acceptable range, and to everyone only a little further north than this, the anoles have long since disappeared anyway. Plus, these are absolutely fabuloso pics, so who am I to deprive the public of such joy?

While nearly all that I saw were juveniles, one was a distinct large adult, clinging almost vertically to a branch.

Actually, this wasn’t during the mist, but the night before after it had stopped raining. Those forelegs are great, though, clutching the branch as if the anole is scared of heights. Don’t look down, little lizard…

I waited patiently, and eventually the anole closed its eyes again.

The raindrops stand out much better from this angle, but now it looks like the anole is praying. Good luck with that.

Okay, now we’re onto the misty night.

pair of juvenile Carolina anoles Anolis carolinensis sleeping nose-to-nose on hairy-stem spiderwort Tradescantia hirsuticaulis
These two were much smaller, and had chosen a hairy-stem spiderwort (Tradescantia hirsuticaulis) to bunk upon. Which is kind of funny, really, since they were a few meters at most from one of the Japanese maples, the one that had hosted up to six anoles in a night and, by virtue of being taller with more leaves to camouflage among, a much better choice to sleep on. Were these two among the six (or more) that had used that tree? Seems reasonably likely, given the distance and the short range that the anoles seem to prowl during the day. Reptile brains are not terribly advanced and it’s possible they retain no memory of where they slept several days or weeks earlier – they just grab a spot convenient to where they are when the sun’s going down, and it’s only because they haven’t wandered far that they choose the same tree.

Or maybe that’s giving them too little credit. On that same tree, there were a few leaves stitched together by a spider, potentially for a nursery, and one anole could be found sleeping in that spot for over a week:

This pic is about six weeks old – I hadn’t used it then because I had been avoiding too many anole posts even then – but an anole of the same size and appearance was in this spot repeatedly, and I have to assume it was the same one. So perhaps they have a better memory than I supposed.

Back to the misty night again. This one was much smaller and, yes, on that same Japanese maple, but the only one, and the only one I’d seen there for several days:

I happened to like this perspective best, and the anole was cooperative enough to have chosen a leaf closer to eye-level (for me, anyway) so I didn’t have to expend a lot of effort to get it.

And then, we return to the first anole seen, the scared devout one – or at least, I think it’s the same one, since again, it was in roughly the same spot on the same bamboo plant, and the same size. But more drops now.

I mean, seriously, I have plenty of wet lizard shots, but do you really think I could pass this one up? Like, look at those drops on the toes! Okay then. I did at least space these out to the next month, even when I could have driven the uploads number higher for October so, you know, sacrifices.

[Speaking of that, we’re currently running third in the number of uploads per year, since the beginning of the blog, and we still have not-quite two months to go. Probably not going to set a record this year, since this would require at least 135 more uploads and that’s pushing it for the winter months, but second place is within reach.]

[Well, 134…]

spring peeper Pseudacris crucifer facing directly into the camera
The warmth and the moisture had also brought out a few different frog species, among them this spring peeper (Pseudacris crucifer,) who purposefully shifted position a couple of times just as I was getting focus pinned down, ruining my composition, until it suddenly turned and faced directly into the camera in a rather accusatory way. No water droplets on this one; their skin distributes the moisture because they like looking shiny. Okay, I don’t really know what the benefit is, except it might help them cling to surfaces without the claws that the anoles have, or it might be an aid to skin respiration – seriously, don’t ask me. As I’ve said before, I just take picchers – an awful lot of the same damn subjects, over and over again, but you stick with what you can handle. It’s cozy and warm in this rut.

Estate Find XLIV

Al Denelsbeck

A rather lackluster find this week, but also the beginnings of a project that might provide for more interesting stuff later on. Otherwise, you’ve seen the recent worthwhile pics, or will in a post soon to follow – they’re all the same subjects I’ve been finding recently anyway.

With the rains came a lot more noisemakers outside, different ones at different hours of the day, and at opportune times I deiced to further test out a bit of experimental apparatus, seen below:

3D-printed parabolic microphone system with recorder, headphones, and powered lapel mic
Nature videography and audio work often requires the ability to isolate and amplify ambient sounds such as animal calls, and there are primarily two different ways to do so: a unidirectional ‘shotgun’ microphone, and a parabolic microphone. This is the latter, only a 3D printed version designed by ‘Gage6917,’ except his didn’t have the printing issues that I had and looks a hell of a lot better.

Shotgun mics have interference slots along the sides of a long tube that cancel out most sounds from the sides, allowing only the sound straight out the end of the tube to dominate, and I’ve been using one of these for a while now with great results. A parabolic mic, on the other hand, focuses sound with a reflector that gathers more of the sound waves that would normally pass by the mic opening, bouncing them to a specific point which is where the mic should be. In my case, we have the digital recorder at bottom and the monitoring headphones to the left, a powered lapel mic to the right, feeding to the actual microphone mounted on the olive green thing in center, specifically that little arm in front of the dish.

3D-printed parabolic microphone
A parabola is a curved surface with a focus point, so that waves (sound/light/etc) that are approaching straight from the front will be reflected to this focus point, while others from off angles will not. Conversely, anything emanating from that focus point will be reflected straight forward; this is the principal behind flashlight reflectors, radar dishes, and telescopes. I don’t really know how to model a parabola in any program, so luckily Gage6917 does and uploaded his design, because purchasing a parabolic dish of any size is damned expensive. Now, decent ones tend to be large, because the longer wavelengths/lower pitches won’t get picked up as well by a smaller dish, but of course a large dish is unwieldy and not very useful in the field, and especially not atop a camera, but this is a nice compromise. Different materials may deaden or alter sounds as well, so most of them are acrylic and not cornstarch-based plastic like the PLA I used.

So how well does it work?, you ask, and I answer, A hell of a lot better than expected. This is me walking around with it at night, homing in on one particular noisemaker, and you can hear the sweeps I make back and forth to narrow down the exact direction as I move closer.

Parabolic mic directional and homing test

My steps can be heard, but this was also shot at night during a heavy mist, so some dripping from trees is in there too, as well as a little bit of handling noise though I was keeping this to a minimum. But there was no question when the parabolic mic was pointing right straight at the thing producing the noise, in this case a variety of cricket. I was hoping to get the spring peepers that have sounded off occasionally, but they weren’t cooperating while I was out there.

Another, this time during the day yesterday; The Girlfriend and I have been hearing these sounds routinely near the pond, usually narrowing it down to a rough area, but the sounds can play tricks on our ears and sometimes we’re shifting back and forth to try and determine just where it is. The parabolic mic, however, took the uncertainty out.

Parabolic mic directional and homing test, part 2

You can hear my comments within, and just as I was leaning over the exact spot, a green frog leapt from cover right there, making me believe that it was the one creating the noise. Then I was confused, because that’s not the noise green frogs make in the slightest – it was a mere coincidence. Moreover, none of the other frogs or toads in the area make this noise either, and I eventually narrowed it down to likely a northern mole cricket, or at least a member of the mole cricket family, which makes sense given the conditions and location plotted.

That linked page also indicates that the trills are actually 8 very rapid pulses at about 2 kHz in frequency, which means nothing unless you’re either quite adept at hearing pitches, or can use Audacity to determine frequency:

frequency plot from Audacity indicating ten pulses peaking at 2 kHz, likely confirming this as a mole cricket call
Okay, so that’s ten pulses, not eight, as you can see from the highlighted section to the right, while the frequency plots a distinct peak at 2000 Hz, or 2kHz. I’d say that’s a pretty damn close match. But notice how different it is from another species of mole cricket captured here.

I also went exploring behind the pond and along the edge of the creek that borders the property, hoping to hear something interesting. If you listen carefully to the file below, you’ll hear a faint ka-thunk in there.

Parabolic mic directional and homing test

That’s clearly a beaver diving – heard it too many times before. This one was behind me, however, directly opposite the mic direction, otherwise it should have been many times louder. I also heard something crashing away from me through the leaves, naturally while I was not recording, and by the time I’d started recording the sound had ceased. Curiously, this came from behind me at a spot that I’d passed only 30 seconds earlier, so we somehow crossed paths in a narrow isthmus between pond and creek. I suspected something had come out of the pond just behind me before discovering that I was there, though I only heard one brief splash and the duckweed was undisturbed in that area. Shame I wasn’t recording though.

The goal now is to make a few small modifications to the design, specifically adding a hotshoe mount so it can go atop the camera, but also a manner to tuck the wires in better and perhaps isolate the mic itself from the vibrations of handling the parabola or the camera it’s mounted upon. And a wind shield, but that’s easy enough to add. I really want to try this out on the wood duck video work.

Kill the stage lights on October

Al Denelsbeck

Yes, we’ve reached the end, which should be plentiful obvious if you’re in the US at least, as the frivolous but nonetheless enjoyable holiday rolls in. As we discovered last year, we see practically no Trick-or-Treaters here at Walkabout Estates Plus, which is kind of a shame – we’ll see what happens this evening.

But the End-Of-Month Abstract waits for no one! Well, except me sometimes when I forget it’s coming up and post late. This is not one of those times, so let’s see what October has in its treat bowl.

abstract image of maybe a leaf or something?
I ‘discovered’ this one when looking at the original, since this is a close crop, and I’ll be back to explain it later. But it fits, at least.

And another, the one I had originally slotted for this, also unintentional:

closeup of Carolina anole Anolis carolinensis within elephant ear stem, overexposed
I was on the fine edge of discarding this one during the sort, until I realized how it looked when cropped. This was an exposure mistake that occurred (notice how I didn’t say, “that I made”?) while getting the images that I used – it’s all about flash angle and what’s blocked and all that jazz, so it happens from time to time, and why digital has its uses. But the surreal effect is pretty slick, I think – the eye is what makes it work – and this may be a print soon. Or sooner, if anyone specifically requests it…
