This book covers Photoshop from a photographers perspective (as contrasted with an artists perspective). It contains some good sections on color correction, but falls short of being an essential Photoshop book. It is very expensive, contains uninspired examples and has several minor annoyances such as sections on outdated equipment ...poorly cropped/grainy/unnecessary screenshots and somewhat questionable chapter organization and overlap. I think it is a helpful book, but is not in the same class as something like the "Photoshop WOW!" series, which is more complete and ultimately more useful.
