The method described is a modern, more automated version of the basic stacking technique. The six-legged image I posted this time is done with a more manual approach. Camera on tripod,(live) subject quite still. Bugs/butterflies etc. don’t move much below 55° F. Flowers don’t move much when there is no breeze. Focus on front edge of subject, or even a little closer, take first frame. Advance just very slightly, take 2nd frame. Repeat until focal point is well behind the subject. Stack and view in the proper software. Delete frames that are not contributing to the overall, repeat the stack-and-view. Repeat until it looks good to you.
I have seen some exceptional “product photography” stacked images, e.g., an image of a Rolex watch that was incredible. So the subject needn’t be “deaed”, just very very still.
