Summer Insects

Here are some insects from last July and August.

northeastern hammertail, a robber fly (focus stack of 5 images)

Is it just me, or does this ant have transparent rings in its abdomen? (focus stack of 2 images)

Focus Stacking Artifacts

The focus-stacking software I use can introduce artifacts into images.

 

Sometimes a "reflection" is generated. Here, there's one across the bottom. (Check out the crablike spider at the top.)

 

As I was shooting this caterpillar, an ant made its way along a lovage stem, and focus stacking gave ghost ants. There are reflections at the top and bottom, too.

Without ghost ants

When I shoot macro with focus stacking in mind, I set the lens to the closest focusing distance and then approach the subject until just before it's in focus. Then I shoot a burst as I move the lens closer.

I wanted the bug in addition to the bee. The bug was closest to the lens, so for the focus stack I chose an image with the bug and then skipped some images until the bee was in focus. The result is a semitransparent effect. This happens somewhat often and I haven't figured out when it's likely.

Without the image of the bug in-focus, the bee is less ghostly.

To get the picture I wanted, I took the previous image and pasted-in the bug and parts of the flower.

Mantis Focus Stack

A while ago I assembled an image of a praying mantis from five separate pictures. I recently upgraded PaintShop Pro (cheapskate Photoshop that I can pay for once) because of its focus-stacking feature. Focus-stacking software takes a set of pictures and mashes them together, using the in-focus bits of each one.

Here's that mantis, as created by PaintShop Pro:

It's not perfect, but it's better than I can do and is a helluva lot easier.
