 Language is a very complicated thing, and that’s one of the reasons why I like making photographs. 

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. 

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. 

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

 Art has a lot in common with madness. After all, why should one get involved with art? You can live normally like everyone else—which is to say, as stupidly as everyone else. 

Dennis Oppenheim
[Artist, b. 1938, Electric City, Washington, d. 2011, New York.]

 You can’t understand how strange it was to be a sculptor who exhibited photographs. (On exhibitions of his “earthworks” and land art pieces.) 

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.) 

Craig Owens
[Writer and critic, b. 1950, d. 1990.]

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

Michael Ondaatje
[Writer, b. 1943, Colombo, Ceylon (now Sri Lanka), lives in Toronto, Canada.]

 You can see that the care he took defiling the beauty he had forced in them was as precise and clean as his good hands which at night had developed the negatives, floating the sheets in the correct acids and watching the faces and breasts and pubic triangles and sofas emerge. The making and destroying coming from the same source, same lust, same surgery his brain was capable of. (On New Orleans photographer E. J. Bellocq)
