Photoshop.Blending.Modes.Cookbook.for.Digital.Photographers

The book is arranged into three parts. This first section
describes where blending modes are found, how to use
them, and how they work. Blending Modes in Detail, page 20
describes each mode more closely and shows the result of
various self-blends and opacity changes. Here I also point out
interesting applications of a specific blending mode—using
Overlay to add lens flare, for example. Then it’s on to the
Recipes, page 62, the book’s third and biggest section,
featuring step-by-step instructions and examples.
