One of the best ways for you to learn about photography is to study examples of how to hold your camera and work your subject during photo shoots. In addition, you can talk to someone who has been in photography for a long time to gain valuable insight on your craft.
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.
