The great French photographer Henri Cartier-Bresson once gave the classic definition of photography as the art of capturing movement at the "decisive moment." In other words, the quality of the finished photograph is decided in the split-second when the shutter is pressed.
法國的攝影大師布烈松曾經替攝影留下一句經典性註解，他覺得「攝影就是捕捉瞬間動作的巧妙安排」，換句話說，攝影的完成在按下快門那幾百分之一秒的剎那便決定了。
