 The business of the state trying to legislate modesty is relatively both an infantile and ridiculous procedure. Of course, it is true that the more things are secreted the more intriguing they become, because it is always the forbidden that has the strongest appeal. Nudity is a state of fact—lewdity a state of mind.

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

 We’d make love. Afterwards he would take photographs of me. (On modeling for Alfred Stieglitz) 

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. 

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. 

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.

[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. 

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.) 

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.
