The guy was talking a lot of shit about these butterfly pictures, but they were technically challenging to get right.
The DoF on a 3-5x magnification shot on 8x10 is incredibly thin and diffusion effect is exaggerated significantly when shooting at high magnification.

I even had to develop my own focusing techniques to be able to get such fine focus on the high level magnification. There was no manual or any info online about how to take these shots.

These look stunning when contact printed on azo paper with amidol developer.
