For anyone upgrading from CS2 to CS3 (or even from CS), this is the one book that will get you fluent faster than any other book. Don't let the relatively slim size of the book fool you. Ben packs in all the information so that you can figure out how to take advantage of the new interface, with the new Palettes, the Dock, and how to most efficiently use it. The new Bridge interface and features is covered in depth, as is Camera Raw 4, the new look for layer, improvements to Curves (after all these years), Vanishing Point, the Quick Selection tool, and all the rest. I got Ben's last version of this book when CS2 came out and it helped me master the new features in a few days, rather than weeks. If you've read the articles, seen the NAPP videos (great, at photoshopuser.com, but lacking the detail of this book) and you are ready to get seriously into CS3, this book will take you there.
