Incorporate things like roads, streams, shorelines, railway lines, or even railings, into your images. These are referred to as lead lines and are a great way to capture the way that a viewer is going to look at your photo. They will lead your viewer's eyes through the scenes of your photos.
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.
Make use of the instant feedback you get from a digital camera. The screen on your digital camera can show you the basics of how your photo came out the instant you snap the shot. Learn from your mistakes and take another shot, there's no need to wait for your prints anymore.
