Query: This is a must have for any photoshop user!

I purchased this book not knowing much about Photoshop but being a photographer I needed to learn and learn quick so I could perform my job. This book is the best thing I have bought in a long time. The instruction was simple and I was working away in just 4 hours. I could not reccomend a better book than this. You also can't find a better deal than this price!
