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 SzarkowskiPhotography is the easiest thing in the world if one is willing to accept pictures that are flaccid, limp, bland, banal, indiscriminately informative, and pointless. But if one insists in a photograph that is both complex and vigorous it is almost impossible
John SzarkowskiThe basic material of photographs is not intrinsically beautiful. It's not like ivory or tapestry or bronze or oil on canvas. You're not supposed to look at the thing, you're supposed to look through it. It's a window.
