"Many people, even some good photographers, talk of the "luck" of photography, as if that were a disparagement. And it is true that luck is constantly at work. It is one of the cardinal creative forces in the universe, one which a photographer has unique equipment for collaborating with. And a photographer often shoots around a subject, especially one that is highly mobile and in continuous and swift development which seems to me as much his natural business as it is for a poet who is really in the grip of his poem to alter and re-alter the words in his line. It is true that most artists, though they know their own talent and its gifts as luck, work as well as they can against luck, and that in most good works of art, as in little else in creation, luck is either locked out or locked in and semi-domesticated, or put to wholly constructive work; but it is peculiarly a part of the good photographer's adventure to know where luck is most likely to lie in the stream, to hook it, and to bring it in without unfair play and without too much subduing it."
