Praying Mantis

I tried to make a composite image of a gecko, and that was a failure. A composite chameleon was simpler and better. Since then, I tried to make a macro composite of a cicada exoskeleton.

That proved to be beyond me. Keeping the antennas and hairs while adding in-focus legs was difficult. Also, as the focus changes, elements of the image appear to move. An out-of-focus leg is smeared wider than the same leg that in focus, so when I put the in-focus leg on top of the out-of-focus leg, the leg ended up with a tan halo. If I included part of the background (a window screen), that didn't work because the screen's wires from different pictures didn't line up. A solid-color background would help.

There are tools that make this kind of thing easier. A camera can be mounted on a focus rail. Then, after an initial focus, a picture is taken, and the camera is moved a small, measured distance before the next picture is taken. That has the effect of changing the focus at consistent intervals without touching the camera. Then, after taking tens of pictures, focus-stacking software, as it's called, takes all the pictures and makes one image with everything in focus. I don't know how seriously I want to pursue this, and I'm a cheapskate, so I'm not buying anything. Yet.

I decided to stop trying to make composite images, until the missing gardener pointed-out a praying (could be "preying," no?) mantis.


I thought I might be able to make a composite of the mantis's body because it doesn't have a lot of projections. I started with the head and "neck" and worked my way back. That turned out okay, but I decided to make another composite starting at the other end, and that's what you see here. I used five shots.

It's not bad, especially at a smaller size. There are lines across the plant stems, and other artifacts are visible at a larger size.

Here are five pictures.

Canids

Woof! Sort of.

Gray wolves come in many colors.

gray wolf (Toledo Zoo)

Litter-mates and brother gray wolves Loki, Lobo, and Tundra (Toledo Zoo)

gray wolf (Minnesota Zoo)

Mexican wolf, a subspecies of the gray wolf (Columbus Zoo). It's gnawing on an antler.

bat-eared foxes (Columbus Zoo)

African painted dog (Cincinnati Zoo)

dingo (Toledo Zoo)

Stevie, a red fox (Columbus Zoo). She's pretty skittish and looks at me warily.

Stevie. Red foxes of this color phase are known as silver foxes. A red fox at the Minnesota Zoo is mottled black and tan/red (my two pictures are bad).

2021 Part 3

red-tailed rat snake (Columbus Zoo)

A carpenter bee (PDF from ODNR), maybe (my yard). It's a lousy picture, but check out the bug on the bee's face.

Saltwater fish (Minnesota Zoo). I like the bright colors in the midst of the darker colors.

transcaspian urial (Minnesota Zoo)

Egyptian plover (Toledo Zoo)

I'm thinking Herbie, but this could be Emma (Toledo Zoo)

red-crested cardinal (Toledo Zoo)

2021 Part 2

 2021 favorites, Part 2. All photos are from the Columbus Zoo.

Siamang family, May 25. Well, I assume this is a family. Olga and Rashid had a baby in 2020.

Siamang youngster, June 22. I assume this is the same youngster as in the previous picture.

A harbor seal catches a fish.

Columbia, a California sea lion, tries to see what's what.

Frustration. This was a great scene of elephant ladies (and a little of Frankie at the left) throwing dust on themselves, but I could not get a good view thanks to tall grass and the fence.

A spider in the okapi enclosure.
