See? You're not sure what you can and can't do?

Heheh. Ice-boy says it's all just parameter values, not programming, and anyway you can't copyright ideas, only implementations. Post it.

By the way, maybe you don't want GC or sRGB either - maybe you want tone mapping, particularly HSV exponential tone mapping. Physics isn't everything - sometimes CG is about art.

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)
