We must place ourselves and our camera in the right relationship with the subject, and it is in fitting the latter into the frame of the viewfinder that the problems of composition begin. This recognition, in real life, of a rhythm of surfaces, lines, and values is for me the essence of photography; composition should be a constant preoccupation, being a simultaneous coalition – an organic coordination of visual elements. Composition does not just happen; there must be a need for expression, and substance cannot be divorced from form.
