Composite images: “Generic Gomphid”

“It’s like Deja vu all over again.” (Source Credit: Yogi Berra.) But seriously folks, if you were thinking “Hey these pictures look familiar!” then you’re right. My last blog post features “one-offs” of the same subject, that is, photos with a single focus point on the mid-body of the specimen.

This post features focus-stacked composite images that show dorsal- and ventral views of a preserved larva in the Family Gomphidae (Clubtails) that was collected by Bob Perkins. I think both composite images look better than the “one-offs” in my last blog post; the difference is especially noticeable by looking at the head and tail in the vernal view.

Dorsal

Five (5) photos were used to create the first focus stack. A single focus point was positioned over select anatomical features; photos were taken at each point of interest.

All flashes were set for Manual Mode at 1/128 power.

Adobe Photoshop CC 2017 was used to create the preceding focus-stacked composite images, as well as spot-heal and sharpen the final output.
