hey guys, I love forums so i figured there had to be one or two floating around. I am 110% new to photography, but decided to pick up a DSLR. I got a Sony A330. I was told that a Nikon/Canon Rebel/or Sony A330 would be a good starter camera. I am confused on what everything means. Where would a good place be so that I could learn what the ISO does or how all this stuff plays into my shots??
