 Representation, then, is not—nor can it be—neutral; it is an act—indeed the founding act—of power in our culture. 

Gabriel Orozco
[Artist, b. 1962, Jalapa, Veracruz, Mexico, lives in New York, Paris, and Mexico City.]

 Photography is more than a window for me. Photography is more like a “space” that tries to capture situations. 

Paul Outerbridge
[Photographer, b. 1896, New York, d. 1958, Laguna Beach, California.]

 What this country needs is more and better nudes. 

Georgia O'Keeffe
[Artist, b. 1887, Sun Prairie, Wisconsin, d. 1986, Santa Fe, New Mexico.]

 If they had known what a close relationship he would have needed to photograph [them] the way he photographed me—I think they wouldn’t have been interested. (On men who wanted Alfred Stieglitz to photograph their wives or girlfriends, 1922.) 

Roman Opalka
[Artist, b. 1931, Hocquincourt, France, d. 2011, Rome.]

George Orwell (Eric Arthur Blair)
[Writer, b. 1903, Motihari, Bengal, India, d. 1950, London.]

Timothy O'Sullivan
[Photographer, b. 1840, Ireland or New York (disputed), d. 1882, Staten Island, New York.]

 The battle of Bull Run would have been photographed “close up” but for the fact that a shell from one of the rebel field-pieces took away the photographer’s camera. 

Ruth Orkin
[Photographer, b. 1921, Boston, Massachusetts, d. 1985, New York.]

 To be a photojournalist takes experience, skill, endurance, energy, salesmanship, organization, wheedling, climbing, gatecrashing, etc. – plus an eye and patience.
