Q&A

Q1: Okay, just what does the Constant slider (at the bottom of the Channel Mixer dialog) actually do?

A1: Believe it or not, it simply darkens or brightens the entire image. Drag it to the left, and the entire image gets darker. Drag it to the right, and it gets lighter. Because I'm trying to create extreme contrast, I often darken the entire image using the Constant slider (by dragging it to the left) so the shadow areas get really dark, then I use the Red, Green, and Blue sliders to brighten things up.
