Macro Photo of stink bug, using 2 images to reduce DOF. Took this image in 2019 but could not stack it, as I could not find stacking app free of cost. One of the cons of Mac!

What is focus stacking?

technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images. https://en.wikipedia.org/wiki/Focus_stacking

Quick tutorial

To take shots at different focus distance, it's advised to use focus slider, I got one, but I rarely use it. The issue is that in the wild it's pretty useless. To get this shot I shot burst of shot while moving very slowly. It's a hit or a miss. This particular image, I got just 2 usable shot. Software for focus stacking has come a long way, I used Affinity by Serif. It worked.
