 Photography has always been a simple medium, compared to painting in oil or chipping at marble. 

Andreas Gursky
[Photographer, b. 1955, Leipzig, Germany, lives in Dusseldorf.]

 Since the photographic medium has been digitized, a fixed definition of the term “photography” has become impossible.

 To hell with this. I’m going to go down to Cocoa Beach. (On being told by NASA that he couldn’t take a camera on his historic first space flight, forcing him to make a trip to a Florida drugstore where he bought the Ansco Autoset snapshot camera and two rolls of Kodak film he used on the flight.)

 Content to me is very important, but I like it when [the photograph] is also enigmatic. If you don’t know what it is you begin to speculate, and that is what I want. 

Jonathan Green
[Writer, photographer, and curator, b. 1939, lives in Riverside, California.]

 The camera cannot lie, neither can it tell the truth. It can only transform. The very nature of the medium forces a disjuncture between the photograph and the world, yet the habits of perception—our everyday use of photography—forces us to see the image as surrogate reality. 

Andy Goldsworthy
[Artist, b. 1956, Cheshire, England, lives in Dumfriesshire, Scotland.]

 Photography is a way of putting distance between myself and the work which sometimes helps me to see more clearly what it is that I have made. 

Clement Greenberg
[Critic, b. 1909, New York, d. 1994, New York.]

 ...there is about him and some of his disciples too much art with a capital A, and too many swans in his park are only geese. (1942, on Alfred Stieglitz) 

Ron Galella
[Photographer, b. 1931, Bronx, New York, lives in New York.]

 My job is thick with risks, threats, occasional violence and sometimes the necessary folly that sometimes courts humiliation and ridicule. But I don’t care. I see myself as the dean of American paparazzi.
