Fastest way to create a brightness control

Alpha blt with white seems to just wash out the graphics, does anyone know a true way to brighten. (Might be time to go break out the graphics gems books)

That's a very nice piece of code.

Does anyone knows how to adjust the color saturation? I suppose there is a formula along the same lines, but I can't seem to locate anything on the web...

Thanks!

The last gamma adjustment control I saw in a game was for a Jimmy Soft game, which were all done using Jimmy's custom graphics library. I don't recall if his just adjusted the brightness of the backlight or not however.

On the PC gamma is done through the video card so it's nice and fast. In the past it was done through the equations I posted in this article earlier. Obviously an optimized version there of.

If noone else has, I think I'll go ahead and start on one this coming week.
