By the way - the last bit of photorealism must come in postwork. Shaders cannot simulate the bright highlights bouncing around in a system of lenses and Poser's "camera" has nothing in it to cause it to behave like a real camera. So a little postwork is necessary to make the highlights glow properly as in a photo and also to tweak exposure level a little because re-rendering with more light over and over is just too tedious.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
