Dennis Oppenheim

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

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

 [A photograph] should do something to the beholder; either give a more complete appreciation of beauty, or, if nothing else, even a good mental kick in the pants. 

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) 

Bill Owens
[Photographer, b. 1938, San Jose, California, lives in Hayward, California.]

 Photoshop is not in my vocabulary. I don’t need it because I have content. 

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

 It was true that there was no such person as Comrade Oglivy, but a few lines of print and a couple of faked photographs would soon bring him into existence... Comrade Oglivy, who had never existed in the present, now existed in the past, and when once the act of forgery was forgotten, he would exist just as authentically, and upon the same evidence, as Charlemagne or Julius Caesar. 

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. 

Orlan (Mireille Suzanne Francette Porte)
[Artist, b. 1947, St. Etienne, France, lives in Ivry-sur-Seine, France.]

 I make myself into a new image in order to produce new images. 

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

 We normally consider stability to be the constant in life and accidents to be the exception, but it’s exactly the opposite. In reality, the accident is the rule and stability is the exception.
