The simplicity of photography lies in the fact that it is very easy to make a picture. The staggering complexity of it lies in the fact that a thousand other pictures of the same subject would have been equally easy.
John SzarkowskiPhotography is a system of visual editing. At bottom, it is a matter of surrounding with a frame a portion of one's cone of vision, while standing in the right place at the right time. Like chess, or writing, it is a matter of choosing from among given possibilities, but in the case of photography the number of possibilities is not finite but infinite.
