Query: Best book on Photoshop for photographersoks

This book is the best I have read on Photoshop. It has more practical and useful techniques than any other book, and I have read a bunch of the best known books on this subject.I liked the book so much, I ended up buying Jack Davis' DVD set of the same name from Software Cinema. The DVD's are the movie version of the book and very useful if you are a photographer.Other reviewers have spelled out many features in the book. I particularly found interesting the lucid explanations, for example, of Dodge and Burn with Layer Masks. The book's explanation and practical examples of using the Blend-if options with Layers is the best I have seen anywhere. And the really best way to use the power of Hue & Saturation command - mind-boggling.I used Photoshop Elements for a couple of years and bought Photoshop CS a few months ago and felt lost for a while. Of several books I got on Photoshop Cs, this one has brought me up to speed.
