What an exquisite collection of great shots, with the obvious exception
of the sillyness posted by yours truly. Kudos to one and all.
I'm still fascinated by Mark's wasp. How is this done with a manual
focus lens? Adjusting the focus in 135 microskopic steps? My mind
boggles. Please explain.

Mark appears to have mastered image stacking. It is exactly how you
describe it.

Ralf, I very much appreciated your sensitive and careful photo of the poor robo critter. It is always sad to see this happen, but at least its existence was memorialized…
In short, not ‘silly “ in my opinion, but rather, a clever take on the theme!

I think that such stacking is done by moving the camera. Put it on a
rack, and move the rack the same fraction of a turn of the handle for
each shot. I was told someplace that the magnification changes less by
moving the camera than it does by changing the focus.
I've never tried such hijinx I'm afraid.

That would take rather a lot of time. How do you keep the subject from
moving?

I can assure you that it's still alive and well and my little jig for
straightening its legs has worked nicely.

Your subject was such a dip.

I've watched Jostein doing this. His contraption was/is electrically powered, so once the setup is complete, you only need to press the go button. There are a large number of hard parts for this type of work but one of the hardest is preparing the specimen; removing dust and other pollutants, arranging parts (animal subjects are almost invariably deceased) and otherwise posing and lighting.
I seem to remember that Jostein's rig could have both the number and size of the increments altered. Difficulties include calculating the depth oo movement such that you do not run out of focus, leaving either the front or rear of the subject blurred.
