So I picked up the adobe photosho0p cs3 book for digital photographers and I must say that I'm really happy with it so far. It goes into detail about not just the theory behind certain adjustments, but the how to, how much (if there is a certain "how much") and why. My earlier post about how to convert to black and white.... I found several different ways to do it in the book, and found out my favorite way is using calculations. Tons of useful info in the book, just thought I'd pass it on. I'll post some PP photos soon showing some of the techniques I've learned.
