First of all, sorry if this is the wrong board to post this in. I'm just starting out as my username shows. I just purchased a Powershot G1. I've been playing around with it and learned some basic things. I want to learn more about topics such as shutter speed, appature, etc. and how they affect the pictures I take. I also want to get assignment/practice ideas. Can anyone suggest some good books on the aforementioned topics?
Thanks
