Pure photography is a system of picture-making that describes more or less faithfully what might be seen through a rectangular frame from a particular vantage point at a given moment.
John SzarkowskiThe invention of photography provided a radically new picture-making process - a process based not on synthesis but on selection. The difference was a basic one. Paintings were made - constructed from a storehouse of traditional schemes and skills and attitudes - but photographs, as the man on the street put, were taken.
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.
