I know that many here are long of tooth and there are some who won't be able to learn new tricks, however while doing a bit of web surfing I came upon a very decent bit on composition. This is from the National Geographic website and is, IMHO, well worth taking a look at regardless of one's experience. Bill Barber
I remember reading through National Geographic as a kid and being in awe looking at the photos. Don't know what it's like now but 20 years ago the photos in the magazines were amazing.
