Are you interested in becoming a great photographer?  Maybe you are thinking about taking up photography as a hobby.  Or maybe you are thinking about making it a little side business.  Regardless of whether you are thinking about doing photography as a hobby or a business, you have to start somewhere on the road to learning about photography. 
Most people think that the key to taking great photos is having high quality, expensive equipment, and although the high quality equipment is nice to have, it doesn't guarantee great photos.  You can take great photos with all kinds of cameras and really the key to having nice pictures is the technique you use, knowing the best ways to maximize your particular camera, and avoiding common mistakes.
