Johan, thanks for replying. > The colorweel lets you select a color, the question is how that color > is applied to the image, ie. is it an add, mult or gamma? Yes, this is exactly what I am wondering about. > An add or mult will affect your white points, 1, gamma will not. How does add or mult affect the whites? If I add onto white, it will stay white - or the result will be over-white and then get clipped to white. This is what I think Photoshop does. If you move the R slider right it adds red, if you move it left, it subtracts red. This obviously would not affect white, since white plus anything is still white in RGB.
