Quote - Heheh. "Some Color" to the 2.2 power is anti-gamma correcting the color - making it linear, instead of sRGB.

You've illustrated my point, Bill. Was it through experimentation that you arrived at that knowledge of Color_math Pow functionality? If it was, I despair at ever getting anywhere with what I'm doing with my so-called experiments. I wouldn't have come to that ... ever.

What do you mean: "linear"? vs sRGB? No, please don't tell me: is there a place where I can study it for myself? I don't want free handouts: I just want to study this carefully... very carefully. Then, perhaps all those experiments might mean something.

I certainly hope you do write your book, Bill, but based on the instructions you've given the group of which I understand so darn little, I'll need the Cliff Notes to go with it.

Oh, and thank you for explaining why the math_functions Add was plugged in there. At least now I know that the reasons I'd postulated for it to be there, weren't correct.
