Feel free to add your own. Aaron Siskind: "Photography is like air. I couldn't live without it." "To take a photograph is to align the head, the eye and the heart. It's a way of life." - Henri Cartier Bresson “Your first 10,000 photographs are your worst.”- Henri Cartier-Bresson ...However, for the digital age, maybe it needs to be updated to: “Your first 100,000 digital photographs are your worst.” "Actually, I'm not all that interested in the subject of photography. Once the picture is in the box, I'm not all that interested in what happens next. Hunters, after all, aren't cooks." - Henri Cartier-Bresson "The voyage of discovery lies not in finding new landscapes but in finding new eyes."- Marcel Proust "A creator needs only one enthusiast to justify him." - Man Ray "With photography, you zero in; you put a lot of energy into short moments, and then you go on to the next thing." - Robert Mapplethorpe "Why is Form beautiful? Because it helps us meet our worst fear, the suspicion that life may be chaos and that therefore our suffering is without meaning. — Robert Adams "I'd rather give a client one shot that they can't live without, than 100 that they can live with." - Sonya Sanchez Arias Sonya Sanchez Arias "I am not a painter, nor an artist. Therefore I can see straight, and that may be my undoing." - Alfred Stieglitz "A hundredth of a second here, a hundredth of a second there -- even if you put them end to end, they still only add up to one, two, perhaps three seconds, snatched from eternity." - Robert Doisneau "Experience is what you get when you don't get what you wanted, Stock is what you get when you don't get what they wanted." - Anon "I'm always mentally photographing everything as practice." - Minor White "When gifts are given to me through my camera, I accept them graciously." - Minor White It's weird that photographers spend years or even a whole lifetime, trying to capture moments that added together, don't even amount to a couple of hours. ~James Lalropui Keivom When you photograph people in colour you photograph their clothes. But when you photograph people in B&W, you photograph their souls! ~Ted Grant Every time someone tells me how sharp my photos are, I assume that it isn't a very interesting photograph. If it were, they would have more to say. ~Author Unknown The world just does not fit conveniently into the format of a 35mm camera. ~W. Eugene Smith I hate cameras. They are so much more sure than I am about everything. ~John Steinbeck The goal is not to change your subjects, but for the subject to change the photographer. ~Author Unknown I think a photography class should be a requirement in all educational programs because it makes you see the world rather than just look at it. ~Author Unknown The camera can photograph thought. ~Dirk Bogarde My portraits are more about me than they are about the people I photograph. ~Richard Avedon No photographer is as good as the simplest camera. ~Edward Steichen One photo out of focus is a mistake, ten photo out of focus are an experimentation, one hundred photo out of focus are a style. ~Author Unknown All photographs are there to remind us of what we forget. In this - as in other ways - they are the opposite of paintings. Paintings record what the painter remembers. Because each one of us forgets different things, a photo more than a painting may change its meaning according to who is looking at it. ~John Berger I didn't want to tell the tree or weed what it was. I wanted it to tell me something and through me express its meaning in nature. ~Wynn Bullock Photography deals exquisitely with appearances, but nothing is what it appears to be. ~Duane Michals “Photography is one percent talent and ninety-nine percent moving furniture.” - Arnold Newman "The best camera is the one that's with you" - Chase Jarvis "A great photograph is in focus and of a famous person." - Andy Warhol “Beauty can be seen in all things, seeing and composing the beauty is what separates the snapshot from the photograph." – Matt Hardy “Nothing happens when you sit at home. I always make it a point to carry a camera with me at all times…I just shoot at what interests me at that moment." – Elliott Erwitt “Which of my photographs is my favorite? The one I’m going to take tomorrow." – Imogen Cunningham “You’ve got to push yourself harder. You’ve got to start looking for pictures nobody else could take. You’ve got to take the tools you have and probe deeper." – William Albert Allard When teaching a class on the Zone System (sorry to all that just know digital) Ansel Adams asked his friend, Minor White who was visiting, what he would do. Minor just looked at him and said he would probably just bracket it. Ansel laughed. "There is nothing worse than a sharp image of a fuzzy concept." - Ansel Adams "In wisdom gathered over time I have found that every experience is a form of exploration." - Ansel Adams "When words become unclear, I shall focus with photographs. When images become inadequate, I shall be content with silence." - Ansel Adams You don't take a photograph, you make it. - Ansel Adams There are no rules for good photographs, there are only good photographs. - Ansel Adams There are always two people in every picture: the photographer and the viewer. - Ansel Adams There is nothing worse than a sharp image of a fuzzy concept. - Ansel Adams A true photograph need not be explained, nor can it be contained in words. - Ansel Adams Photography is more than a medium for factual communication of ideas. It is a creative art. - Ansel Adams Twelve significant photographs in any one year is a good crop. - Ansel Adams Sometimes I do get to places just when God's ready to have somebody click the shutter. - Ansel Adams No man has the right to dictate what other men should perceive, create or produce, but all should be encouraged to reveal themselves, their perceptions and emotions, and to build confidence in the creative spirit. - Ansel Adams There are worlds of experience beyond the world of the aggressive man, beyond history, and beyond science. The moods and qualities of nature and the revelations of great art are equally difficult to define; we can grasp them only in the depths of our perceptive spirit. - Ansel Adams We must remember that a photograph can hold just as much as we put into it, and no one has ever approached the full possibilities of the medium. - Ansel Adams He who works with his hands is a laborer. He who works with his hands and his head is a craftsman. He who works with his hands, his head and his heart is an artist. -St.Francis of Assisi Some others: http://www.meste.ro/index.html#/quotes

This is ahe most funny  and i like it :

I hate cameras. They are so much more sure than I am about everything. ~John Steinbeck

My two favorites:

"A hundredth of a second here, a hundredth of a second there -- even if you put them end to end, they still only add up to one, two, perhaps three seconds, snatched from eternity." - Robert Doisneau

I think a photography class should be a requirement in all educational programs because it makes you see the world rather than just look at it. ~Author Unknown

While there is perhaps a province in which the photograph can tell us nothing more than what we see with our own eyes, there is another in which it proves to us how little our eyes permit us to see.  ~Dorothea Lange

Often while traveling with a camera we arrive just as the sun slips over the horizon of a moment, too late to expose film, only time enough to expose our hearts.  ~Minor White

A photograph is usually looked at - seldom looked into.  ~Ansel Adams

 Not sure if these were listed already, but...

"Above all, I craved to seize the whole essence, in the confines of one single photograph, of some situation that was in the process of unrolling itself before my eyes." 
~ Henri Cartier-Bresson (French Photographer, 1908-2004)

" Photography is a way of feeling, of touching, of loving. What you have caught on film is captured forever...it remembers the little things, long after you have forgotten everything."
~ Aaron Siskind 

"Dodging and burning are steps to take care of mistakes God made in establishing tonal relationships." ~Ansel Adams

“Pressing the shutter release is neither the beginning nor the end of the photographic process. Rather it is the pivot point upon which preparation and postwork balance.” ~ me
