When I say that a good picture has surprise quality or shock appeal, I do not mean that it is a loud or vulgar picture but, instead, that it stimulates my thinking and intrigues me.

It is every photographer's responsibility to discover new images and a new personal way of looking at things. If he can do this his pictures will command attention and have surprise quality.

Outstanding past work in photography, and in fact in all the arts, is very important to today's photographers. But it should be used for inspiration and not for imitation. These works should be something to be built upon, not to be repeated.

When the novice photographer starts taking pictures, he carries his camera about and shoots everything that interests him. There comes a time when he must crystallize his ideas and set off in an particular direction. He must learn that shooting for the sake of shooting is dull and unprofitable.

Surprise quality can be achieved in many ways. It may be produced by a certain stimulating geometrical relationship between elements in the picture or through the human interest of the situation photographed or by calling our attention to some commonplace but fascinating thing we have never noticed before or it can be achieved by looking at an everyday thing in a new interesting way.

Photographers should make three or four prints from one negative and then crop them differently. When I was art director at Harper's Bazaar and at several agencies as a consultant, young photographers would bring me their portfolios and all the prints would be in the same standard proportions, either for the Leica or the Rolleiflex. Many times, by limiting themselves in this way, they missed the true potentialities of their photographs.

It is the unexpected and the surprise quality of a personal vision, rather than the emotion, which make people respond to a photograph.
