Common names for these are Cave Crickets, Camel Backed Crickets, Spider Cricket, etc... they live in darkness, eat mold and fungus, and are just kind of ichy.
Cave Cricket (family Rhaphidophoridae)
One of my cats goes crazy whenever she sees one of these. She invariably winds up killing and eating them and then .... let's just say they don't agree with her digestion. Oh well...
I shot this a few weeks ago but screwed up and the pin it was mounted on was visible so I cropped in about 20%to eliminate it - made the top of the frame a little tight (I would like to show more of the antennae). 45 stacked images in a single run. DFA 50mm f2.8 macro reverse mounted with minor extension - approx 2x lifesized.

I keep looking for non-insect subjects for stack focused macro photos - they are surprisingly hard to find. I noticed the grey headed coneflowers (Ratibida pinnata) in my prairie plant garden have started budding - so study of the flower bud and its wonderful spiral pattern that suggests the Fibonacci sequence:
That photo is at 4.5x lifesized magnification - here's the full flower at 1x lifesized:
Both images are focused stacked - the top image is made from 60 images in two separate stacks, which were then combined. The bottom image is made from 95 stacked images - I did not expect to need to stack so much for such a low magnification photo, but sheer depth of the subject - roughly 15mm - meant that it took a lot of images to get from front to back.

I had to laugh when I spotted this sign last week... The last time I was in this place - 11 or 12 years ago - I wandered deeper into the woods and found some large wooden signs, covered with just tatters of paper. Beyond that was a tall steep earthen berm and beyond that was an open field. I like open fields... It didn't take long before I knew I was on the wrong end of a shooting range...
This is a film exposure - 35mm Tri-X. Pentax Mz-S, FA 20-35 f4 lens, XI green filter, film devoped in HC110 Dil B. I am reviving my "sun dappled woods" project, last visited in 2008.

I've been keeping watch for interesting insects to photograph, including watching for carpenter ants. So I was pleasantly surprised to stumble onto this very large carpenter ant (Camponotus spp.) yesterday morning:
This ant is roughly 15mm in length. It was dead, laying on the pavement. Base on its size alone, it appears to be a female Carpenter Ant. Looking at it closely shows spots on the thorax where the wings had recently fallen off, so it was probably a recently emerged female looking for a place to nest.
I'm not sure what killed it, but it was near a part of the house that had been treated for a carpenter ant infestation a few years ago. It may have encountered some residual pesticide.
This photo was made at about 2.5x life-sized, which is the magnification that the SMC K 24mm f3.5 yields when reverse mounted onto a DSLR with no additional extension. This image is 50 separate exposures stacked together with Zerene Stacker.
Here's a reference photo of the insect:

I spent last week hanging out in the Hocking Hills State Park in southern Ohio, hiking some of the trails and looking at waterfalls and caves. Here's a photo of the upper falls near Old Man's Cave (click on the image for a larger view):

It's a little misleading in that the place was teeming with tourists when I took this photo. I did not have a tripod so I took a bunch of images at the lowest shutter speed that I could reasonably hand hold the camera - 1/8th of a second. It was a decent compromise in that any single image what reasonably sharp and the water was slightly blurred. Post processing the images today, I stack focused the group in Photoshop and that increased sharpness considerably by blending the sharpest bits of each of the 29 exposures. I then averaged the exposures and that created a more pronounced blur in the moving water. I blended just the blurred water from the averaged composite into the focused stacked composite for the final image. It would have been better to use a tripod and a ND filter, but this way I didn't have to carry so much while hiking.
