William Henry Jackson
[Photographer, b. 1843, Keesville, New York, d. 1942, New York.]

 Portrait photography never had any charms for me, so I sought my subjects from the house-tops, and finally from the hill-tops and about the surrounding country; the taste strengthening as my successes became greater in proportion to the failures.

[Photographer, writer, and curator, b. 1940, Maidenhead, England, d. 2009, Samara, Costa Rica.]

 Making a photograph is as difficult as finding a particularly frisky cat in a dark room. Making a great photograph is as chancy as trying to catch a frisky cat in a black room in which there is no cat. 

Jasper Johns
[Artist, b. 1930, Augusta, Georgia, lives in Sharon, Connecticut and the island of St. Martin.]

 A picture ought to be looked at the same way you look at a radiator. 

Jesse Jackson
[Minister and activist, b. 1941, Greenville, South Carolina, lives in Chicago.]

 Pictures can live in one’s memory. That’s why they are important. 

William James
[Writer, philosopher, and psychologist, b. 1842, New York, d. 1910, Chocoura, New Hampshire.]

 Whilst part of what we perceive comes through our senses from the object before us, another part (and it may be the larger part) always comes out of our own mind. 

Lotte Jacobi
[Photographer, b. 1896, Thorn, West Prussia, (now Torun, Poland), d. 1990, Concord, New Hampshire.]

 I was to be a photographer and that was that. It did everything for me. I love people. I needed the camera more than ever I would have believed. 

James Joyce
[Writer, b. 1882, Rathgar, Ireland, d. 1941, Zurich, Switzerland.]

 ...Ill make him feel all over him till he half faints under me then hell write about me lover and mistress publicly too with our 2 photographs in all the papers when he becomes famous... 

Fredric Jameson
[Writer and theoretician, b. 1934, Cleveland, Ohio, lives in Durham, North Carolina.]

 The visual is essentially pornographic, which is to say that it has its end in rapt, mindless fascination.
