Update: The best of the most recent Photoshop books, by far, are from two of the best-known NAPP (National Association of Photoshop Professional) authors: Scott Kelby's 7-Point System for Adobe Photoshop is probably the most lucid the "here's how I do it" type of books. While the "groundbreaking system" hype is mostly just that, Kelby does indeed reduce Photoshop's huge array of features down into a manageable set of key techniques that solve most of the issues digital photographers face. It doesn't teach you Photoshop, it teaches you how to use Photoshop effectively, a very key difference, and one missing in a lot of the Photoshop books that are out there. At the other end of the spectrum is Matt Kloskowski's Layers: The Complete Guide to Photoshop's Most Powerful Feature. This book does try to teach you about specific Photoshop features, though it also adds the "how to use it" layer (sic) that makes the book useful for virtually any photographer using Photoshop. If you don't know anything about layers, don't worry, Matt does a fine job of getting you up to speed. If you do know about layers and use them, I'll bet you that you still find lots of useful information and tips in this book. Both these books are a must for any Photoshop-using photographer, in my opinion:
