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.
Ah, well.... So we're talking about a macro rail, a stepper motor and
driver electronics, some computer software and, essentially, a *dead*
subject.
Thanks for enlightening me.
