Query: Just a brief introduction to PhotoShop

The book is very good as a brief introduction to PhotoShop, however if you are seriously involved into graphic design, you will need a lot more information. You could "breeze" through the book in five days, so if you buy it,prepare your wallets to spend money for the next one. If you create images as a hobby, the book might be just enough for you.
