Henri Cartier-Bresson was a French photographer and filmmaker known as a pioneer of street photography. His dramatic black-and-white works are among the most iconic images of the 20th century. He insisted, with rare exceptions, on never cropping his images and printing the whole negative.
He believed that whenever you took a photo, it should always be composed in the viewfinder. If he wasn’t happy with the framing or composition, he would disregard the image. “If you start cutting or cropping a good photograph, it means death to the geometrically correct interplay of proportions. Besides, it very rarely happens that a photograph which was feebly composed can be saved by reconstruction of its composition under the darkroom’s enlarger; the integrity of vision is no longer there.”
