Improving one's photography

I don't claim to a be good photographer by any means--I've only pursued it with any passion for a couple months--but I wanted to pass along some tip and techniques which have helped me.

Understanding your basic photographic concepts like aperature, depth of field, and shutter speed is important (read your manual!), but it doesn't matter how technically excellent your photo is if the composition sucks.

I think this is a great starting place. Kodak has a lot of simple tips and techniques. Read the Ten Tips article, try experimenting with all the ideas, then read it again.

Here's another article on composition which had helped me a lot. Everytime I read it I get more out of it. Rinse and repeat.

Here's a great single-source collection of articles on photographic composition I've found. Some of the articles are actually on landscape painting, but they are also very helpful:

Finally, learn from the pros. This list of photog reps which should supply plenty of inspiration (tip of the hat to Spence for the links):
