It is the photographer's decision at the two levels of seeing the picture - when it is shot and when it is chosen and printed that determines his personal style.
Alexey BrodovitchPhotographers 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.
Alexey BrodovitchWhen 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.
