Hello all. Well, I should be studying for my final exams next week, but I felt like taking a break. During my winter break I am hoping to learn as much as I can on how to use Photoshop, but since the learning curve is rather steep I will need a good book to teach/guide me. Does anyone have any suggestions? I currently have Adobe CS (not CS2) and would rather not upgrade for $$ reasons, oh, and I also use a Mac. I would prefer a book that is written for use of Photoshop on a Mac, but hey, any suggestions at all would be great. Thanks!
