+1, very impressive indeed!

Did you have to do a lot of "clean up" of stacking artifacts, given the 140 stack depth?

Yes... always cleanup in some way or another... slabbing and corrections, healing tool, clone tool, etc.. (clone tool for framing errors to smooth out penumbras, healing tool for dust traces) corrections to the flower itself were done by slabbing.

Thanks Bob, good to know that those "corrections" are part of the deal  :) Even though it's been a while since i've done any sort of focus stacking, i always thought i was doing something wrong 'cause the stacks would generally have quite a few anomalies.

Beautiful work!

Deep focus stacks tend to require either excessive retouching, use of substacks ('slabbing'), or both. Highly extended depth of field always comes at a price.

Thanks for the addition Birna!

I didn't know the use of substacks is called slabbing  ???

In 'Zerene-speak' at least.
