 ...photography is made essentially of time. I often think that what we show is a point in time, more than a window onto space. 

Robert Heinecken
[Photographer, b. 1931, Denver, d. 2006, Albuquerque, New Mexico.]

 Many pictures turn out to be limp translations of the known world instead of vital objects which create an intrinsic world of their own. There is a vast difference between taking a picture and making a photograph. 

Roni Horn
[Artist, b. 1955, New York, lives in New York and Iceland.]

 As is often said of photography, this photograph is a frozen moment. A frozen moment is not a moment at all. 

Raoul Hausmann
[Artist, b. 1886, Vienna, d. 1971, Limoges, France.]

 What is important is that our optical awareness rids itself of classical notions of beauty and opens itself more and more to the beauty of the instant and of these surprising points of view that appear for a brief moment and never return; those are what make photography an art. 

Bert Hardy
[Photographer, b. 1913, London, d. 1995, Oxted, England.]

 Everywhere I look and most of the time I look, I see photographs. 

Edward Hopper
[Artist, b. 1882, Nyack, New York, d. 1967, New York.]

 I once got a little camera to use for details of architecture and so forth but the photo was always so different from the perspective the eye gives, I gave it up. 

John Heartfield (Helmut Franz Joseph Herzfeld)
[Artist, b. 1891, Munich, Germany, d. 1968, Berlin.]

 Use Photography as a Weapon! (Sign over the entrance to the John Heartfield room at the 1929 “Film und Foto” exhibition in Stuttgart.) 

Dennis Hopper
[Actor, artist, and photographer, b. 1936, Dodge City, Kansas, d. 2010, Venice, California.]

 “Art” is a bad word in Hollywood. You use “art” too many times and they show you the elevator and then your name is taken off the parking lot.
