Interesting subject. I think we need a bit of a challenge, so it's a welcome change.
Let me see, you said nudes & bodyscapes, b&w, then skin. Not an issue, but I'm thinking:
nowhere did you say it had to be "human"?
Therefore, the field is open to wide interpretation. And interpretation is a big part of what we do here!
Gonna think this one over and crank up the ZI with my preferred B&W film!
