Photoshop book?

Hi. I’m primarily a flash artist/designer, but I’ve always dabbled in photoshop. PS 6 to be exact, and I never formally learned how to use it. I just kind of played with tools and figured out things here and there.

Soon I want to upgrade to the Adobe creative suite, with the new flash, photoshop, illustrator, etc. And I’d like to have a photoshop cs3 book. I’m not really interested in the ‘photograph’ aspects of photoshop, but more of the technical stuff like what all the tools do, how to create a myriad of effects, etc. The top books on amazon seem to be made for photographers, so I figured I’d ask you guys for suggestions.

I’m mostly looking to make nice interfaces, menus, HUDS, to use in my flash movies/games. Also possibly website graphics.
