Query: Not perfect, but pretty good

While it's true this book does not come with a CD full of tutorial files. The thing is, you don't really need them. You can, and probably should, create all the material yourself. That way, you get a chance to experiment and try something a little different than what the authors had in mind. This is how you evolve and become a better Photoshop user. I found this book to be very good at teaching how to be creative in Photoshop. Once you've built a foundation, this is the next step. I'm familiar with some of the functions and uses in Photoshop, but, I'm certainly not an expert. However, I had no problem following the numbered steps in each tutorial. I will say, this is not a book for a complete beginner. You should have some experience with Photoshop. Anyone that buys this book will not regret it. There is so much good information here. I will return to it often.
