There is a creative fraction of a second when you are taking a picture. Your eye must see a composition or an expression that life itself offers you, and you must know with intuition when to click the camera. That is the moment the photographer is creative. Oop! The Moment! Once you miss it, it is gone forever.
Henri Cartier-BressonIn photography, you've got to be quick, quick, quick, quick...Like an animal and a prey.
Henri Cartier-BressonFor the world is movement, and you cannot be stationary in your attitude toward something that is moving.
