Query: Waste of time for intermediate to advanced users

I do not recommend this book to anyone who has ever used Photoshop or designed a web site before. If you don't know anything about Photoshop or web design, than this book might be for you. However, if you want to learn Photoshop I would buy a different book. This book is very basic, so if you know anything about Photoshop than the first half of the book is a waste. I consider myself an intermediate user of Photoshop and I didn't learn a single thing from this book.
