‘Photography 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’

– John Szarkowski (in Sontag, p. 192)
