Make sure you have a focal point for your photograph. This should be the first thing that the viewer's eye is drawn to. Whether it's a flower, a person, or a bird, every shot you take should have a specific focal point. Don't only think about what the focal point is, but figure out the best spot for it in the shot.
Don't be afraid to experiment! With digital cameras, you can now store an incredible amount of photos. Try it out! Don't be afraid to set up your camera at a stream one day and play around with the effects to see what kind of photos you get. It can be a great way to learn what works, and what doesn't.
A great photography tip is to make sure your shots have depth in them. An easy way to achieve that is to be sure that you have a background, a middle ground, and a foreground. Having all three of these will give your pictures a sense of atmospheric perspective.
