I believe that the chief value of photography as a means of communication depends entirely on the ability of the camera to arrest life instantly. It thrills me to speculate how the invention of photography has contributed to the speeding up of human reflexes. The rapidly working camera has sharpened man’s capacity to observe and observe rapidly; it has taught many of us to use our minds to classify visual phenomena in an instant of time; to relate our own attitude to that of the person in front of the camera in a split second. This to my mind is the essence of photojournalism.
