 The candid camera is the greatest liar in the photographic family.... It is anarchic, naïve, and superficial. 

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) 

Franz Kafka
[Writer, b. 1883, Prague, d. 1924, Prague.]

 Your sight does not master the pictures, it is the pictures that master your sight. 

Jeff Koons
[Artist, b. 1955, York, Pennsylvania, lives in New York.]

 The entertainment industry, the advertising industry have taken [the] tools from the art world and made themselves much more politically potent. We are really devastated and very impotent right now. A photographer just working for an advertising company has a platform to be much more politically effective in the world than an artist. 

Frieda Kahlo (Magdalena Carmen Frida Kahlo y Calderón)
[Artist, b. 1907, Mexico City, d. 1954, Mexico City.]

 When my father took my picture in 1932 after my accident, I knew that a battlefield of suffering was in my eyes. From then on, I started looking straight at the lens, unflinching, unsmiling, determined to show that I was a good fighter to the end. (On her father Guillermo Kahlo, 1871-1941, a photographer) 

Rinko Kawauchi
[Photographer, b. 1972, Shiga, Japan, lives in Kanagawa, Japan.]

 It’s not that I’m confident, but I feel it’s okay for me to continue taking photos. 

Diane Keaton
[Actress and photography collector, b. 1946, Los Angeles, lives in Los Angeles.]

 Permanence can only be found in the immortality offered by the click of a camera. Like it or not, life moves on as fleetingly as the photograph is enduring. 

Gertrude Käsebier
[Photographer, b. 1852, Fort Des Moines, Iowa, (now Des Moines), d. 1934, New York.]

 The key to artistic photography is to work out your own thoughts, by yourselves. Imitation leads to certain disaster. New ideas are always antagonized. Do not mind that. If a thing is good it will survive.
