 What you need to be a good photographer is an overwhelming curiosity and a good digestion. 

Diane Arbus

Lawrence Alloway
[Writer, curator, and critic, b. 1927, London, d. 1990, New York.]

 If “a print is the widow of the stone,” to quote Robert Rauschenberg, then a photograph is the twin of an event. 

John Ashbery
[Poet and critic, b. 1927, Rochester, New York, d. 2017, Hudson, New York.]

 For although memories, of a season, for example,
Melt into a single snapshot, one cannot guard, treasure
That stalled moment. It too is flowing, fleeting;

It is a picture of flowing, scenery, though living, mortal,
Over which an abstract action is laid out in blunt,

Harsh strokes.
  

Eddie Adams
[Photojournalist, b. 1933, New Kensington, Pennsylvania, d. 2004, New York.]

 If it makes you laugh, if it makes you cry, if it rips out your heart, that’s a good picture.

Rudolf Arnheim
[Writer and psychologist, b. 1904, Berlin, Germany, d. 2007, Ann Arbor, Michigan.]

 The fundamental peculiarity of the photographic medium; the physical objects themselves print their image by means of the optical and chemical action of light. 

Slim Aarons
[Photographer, b. 1916, New York, d. 2006, Montrose, New York.]

 The only beach I was interested in landing on was one decorated with beautiful seminude girls tanning in a tranquil sun. (On declining a photojournalism offer to cover the Korean War)
