Heh anastasis. I was just trying that effect you mention with a previous image. Cloned the skin color and made a mixer shader with fake fresnel driving it. Tinted each a little, plus some other tweaks. My opinion is that fake fres and similar are wonderful on fabrics. A little procedural bump is definately great on skin, but I haven't yet found the combination that gets those soft glowing highlights natural skin has. Agree with you on the lighting; for me (theatrical lighting designer here!) a clear key (like sun), and a soft base light (like sky dome) gives excellent results on Poser imports. A little GI fills in the cracks quick nicely.
