gamma & brightness ramp calculations

Recommended Posts

is this right? RampComponent = ColorComponent * Gamma + Brightness; i want to make sure its correct, and i don't have a way to test it because it looks like it might be right, but i'm not sure. edit: another thing i forgot about is contrast, where does that figure in? i've tried searching but i can't find anything about how to calculate them, i just get sites talking about it.
