What a fantastic book. I have recently completed a college course in advanced digital image manipulation techniques and learned loads about the power of Photoshop, albeit via CS2. That said, this book complements that course and for any beginner who yearns to become savvy in Photoshop, then this is the one to buy. No, not advanced, but it covers all the basic techniques and gives a worthwhile understanding of Photoshop CS4. Although the "Classroom in a book" series are not cheap to buy, I also bought "Photoshop Lightroom CS2 Classroom in a book" and was similarly impressed (see my review). Why pay an enormous amount of money for Adobe software and then skimp on learning how to get the best out of it? A learners book and worth every penny.
