I was at the local bookstore today and picked up a copy of Understanding Exposure. While there I was looking at books on my Canon XTi. There were two there - one was the Digital Rebel XTi/400D, Digital Field Guide by Charolotte Lowrie, the other was by Michael Guncheon and a company called Magic Laterns. Does anyone have either of these two books and which do you prefer and why? I need to get to know my camera better and the manual only does a so-so job of that - and I need more visuals!!
Thanks for your help and suggestions!
