Though photographers have not ceased to look for beauty, photography is no longer thought to create, under the aegis of beauty, a psychic breakthrough. Ambitious modernists, like Weston and Cartier-Bresson, who understand photography as a genuinely new way of seeing (precise, intelligent, even scientific), have been challenged by photographers of a later generation, like Robert Frank, who want a camera eye that is not piercing but democratic, who don’t claim to be setting new standards for seeing.

— Susan Sontag, On Photography, 1977
