I started this explanation of why preaching composition rules on a forum is a really bad idea, but I decided that I was going to end up with a text book. Let me say this as simply as I can. When a new photographer is sent out to read the rules of composition, nobody bothers to tell him that every rule has hundreds of subtleties. So he runs out and makes his pictures using the rules and thinks my god this is easy, I finally understand all there is to photography. His pictures aren't better because he has been exposed to the so called rules. What he is ... is the guy with the little bit of knowledge that is a dangerous thing. See I cut that down a heck of a lot. There are no easy answers. See if your community college has night classes in adult education photography. If so sign up and you might learn a little about composition. If not shoot pictures, shoot more pictures and when you are sick of it, shoot more pictures. Post them in the galleries and ask for edits and comments. You will begin to understand a little at a time. Good luck and take all these guys, me included, with a full shaker of salt.
