Several iterations of Photoshop ago, I bought Adobe's teaching manual and tried to teach myself everything about Photoshop. The problem was, I never used 90% of it.
Now my son has bought me a copy of CS5, and I'm looking for some advice: All I want to do is some basic compositing -- reconstructing images. I don't want to know about Panoramas or sophisticated printing techniques or color management. I just want to know how to take a cow out of one photo and put it in another landscape, in a way that looks somewhat real. Any suggestions for self-instruction books that don't try to teach you everything there is to know about Photoshop, and where you have to learn everything before you can do anything?
