Given my experience with the earlier version of this book, "Photoshop 5 Studio Techniques", I decided to order "Photoshop 6 Studio Techniques" as soon as it was available. The decision was a good one. "Photoshop 6 Studio Techniques" is a well written, easily understandable, well illustrated book about Photoshop 6 techniques. It covers material from introducing a user to Photoshop through production techniques for both print and web.
Chapters covering curves, color correction, and channels are worth the price of the book. In addition, the chapters that cover retouching, enhancement, and blending present information that is very useful in day-to-day photo editing.
If you use Photoshop 6, I highly recommend "Photoshop 6 Studio Techniques." The book will help you understand basic and advanced techniques that will give images a professional look.
