I'm a keen amateur photographer that specializes in available subject photography. If the subject is a available I shoot it :)
Like most things in life the more time you spend on it the better you will get, and one day I hope to have spend enough time to be half decent.
Photography is a mix between art, being able to see the subject and the light and the potential image,and science then on the other side, understanding your camera shutter speeds ISO Aperture crop factor noise handling.
Photographers often start-off either from the art side or the science side and then overtime develop the other.
