In simple terms, Screen adds color and brightness to dark regions. Whereever the existing pixel is already above a threshold (defined by the color being used as the screen), nothing is added. Where it is under, varying amounts are added, depending on how "dark" the pixel is. So the black regions got full blue color. The gray regions got "blueified". The effect is that a photograph, for example, will get lightened and somewhat colorized, making it appear washed out. I didn't go into excessive detail in the Artists' Guide because I wanted to keep things very introductory. It wasn't meant to be as encompassing as Grokking is. I did, however, have to read through the code to figure out what each mode did. There wasn't any other documentation at the time that described them, and I had never (and still haven't) used Photoshop. -- Michael J.
