“There is nothing in this world that does not have a decisive moment” – This saying came from Cartier-Bresson applied this to his photographic style.
He said: “Photographier: c’est dans un même instant et en une fraction de seconde reconnaître un fait et l’organisation rigoureuse de formes perçues visuellement qui expriment et signifient ce fait” (“Photography is simultaneously and instantaneously the recognition of a fact and the rigorous organization of visually perceived forms that express and signify that fact”)
“Photography is not like painting,” Cartier-Bresson told the Washington post in 1957. “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,” he said. “Oop! The Moment! Once you miss it, it is gone forever.”
