 I don’t like smiley pictures. A smile is a defense mechanism. It says, “You can’t have the real me but here’s my smile.” You get closer to the real person when they stop smiling. 

André Kertész
[Photographer, b. 1894, Budapest, Hungary, d. 1985, New York.]

 You do not have to imagine things; reality gives you all you need. 

Jiddu Krishnamurti
[Religious philosopher, b. 1885, Madanapalle, India, d. 1986, Ojai, California.]

 Relationship between human beings is based on the image-forming, defensive mechanism. In our relationships each of us builds an image about the other, and these two images have relationship, not the human beings themselves...

 The question is: Can I make a photograph that is truly abstract, or must photographs always be representational as reality is there at their core?  

Germaine Krull
[Photographer, b. 1897, Wilda, East Prussia, Germany (now Poland), d. 1985, Wetzlar, Germany.]

 The camera need not invent, manipulate or fool. It does not paint, nor does it imagine. The photographer is a witness, the witness of his time. 

William Klein
[Photographer, b. 1928, New York, lives in Paris.]

 I have always done the opposite of what I was trained to do... Having little technical background, I became a photographer. Adopting a machine, I do my utmost to make it malfunction. For me, to make a photograph is to make an anti-photograph. 

Søren Kierkegaard
[Philosopher, b. 1813, Copenhagen, Denmark, d. 1855, Copenhagen.]

 With the daguerreotype everyone will be able to have their portrait taken—formerly it was only the prominent; and at the same time everything is being done to make us all look exactly the same—so that we shall only need one portrait. 

Alberto Korda
[Photographer, b. 1928, Havana, Cuba, d. 2001, Paris.]

 I remember it as if it were today... seeing him [Che] framed in the viewfinder, with that expression. I am still startled by the impact... it shakes me so powerfully. (On his iconic photo of Che Guevara)
