Thanks for the advice, I've ordered Adobe Photoshop CS2 for Photographers by Martin Evening, it will be here in a couple of days. $32.31 shipped from Amazon.com
Excellent choice. I sit here with it at hand. I also have an old version--maybe for 6?? Still good, but CS2 is quite a bit different. I'd also add Bruce Fraser's RAW book is good--and if and when you get further advanced, you might like one of Katrin Eismann's--"Masking and Compositing' or 'Restoration and Retouching' (my favorite).
BTW--there are excellent tutes out there that you can usually find just by Googling.
