I'm just starting to break out of the auto mode on my EOS Digital Rebel xti and I'm overwhelmed. I want to learn and I'm wondering is it better to first read a book geared to specifically learning about the EOS?, or just jump in with the big picture and learn the general big concepts first. I started reading the tutorial thread here (which is great) but I just want to make sure that I'm not better off with a "Hi. I'm the EOS and it's nice to meet you" first book. Thanks.
