I'm a professional photographer who uses Photoshop daily in my business. The things I know how to do, I know very well, but I'm always looking to expand my uses for the program. For instance, I would like to know more about design functions, how I could use CS4 in marketing my business, new ways to use type, etc. These are the things I don't use all the time.
Instead, this is basically a beginners book. Another rehash of tools, functions and fundamentals, but definintly NOT how to do everything or even how to do ANYTHING new.
If you are a beginner, fine. I would even go so far as to say this is a pretty good beginner book. But if you were really looking for something different, look elsewhere. For me, this book was a big disappointment and the title is all marketing hype.
