Mark Twain (Samuel Langhorne Clemens)
[Writer, b. 1835, Hannibal, Missouri, d. 1910, Redding, Connecticut.]
My dear Sir, I thank you very much for your letter and your photograph. In my opinion you are more like me than any other of my numerous doubles. I may even say that you resemble me more closely than I do myself. In fact, I intend to use your picture to shave by. Yours thankfully, S. Clemens.
(Reply to a man who sent him a photograph and claimed to be his double.)

[Photographer, b. 1968, Connecticut, lives in New York.]
People say photos don’t lie. Mine do. I make mine lie.
Buckminster Fuller
[Inventor and philosopher, b. 1895, Milton, Massachusetts, d. 1983, Los Angeles.]
Seeing-is-believing is a blind spot in man’s vision.
Edmundo Desnoes
[Writer, b. 1930, Havana, Cuba, lives in New York.]
Photography has fooled the world. There’s no more convincing fraud. Its images are nothing but the expression of the invisible man working behind the camera. They are not reality, they form part of the language of culture.
Lady Elizabeth Eastlake (Elizabeth Rigby)
[Writer and photographer, b. 1809, London, d. 1893, London.]
Thus are the incidents of time, and the forms of space, simultaneously recorded; and every picture becomes an authentic chapter in the history of the world.
(1857)
David Levi Strauss
[Writer and critic, b. 1953, Junction City, Kansas, lives in New York.]
Seeing is believing, but photographs are more accessible.
Andy Grundberg
[Critic, curator, and educator, lives in Washington, D.C.]
Computer images, like camera images today, will be seen as representations of a simulated, second-degree reality with little or no connection to the unmediated world. This is one lesson we can learn from photographs, and especially from those of the last 25 years: images exist not to be believed, but to be interrogated.
Errol Morris
[Documentary filmmaker, b. 1948, Hewlett, New York, lives in Cambridge, Massachusetts.]
...we do not form our beliefs on the basis of what we see; rather, what we see is often determined by our beliefs.
