Bullock, Wynn at English => English (The Britannica Concise) Of Explained:
U.S. photographer. Born in Chicago, he was strongly influenced in his early work--mainly "solarizations," in which the image is partly negative and partly positive--by the avant-garde experiments of L. Moholy-Nagy. In 1948 E. Weston persuaded him to focus on realism and tonal beauty, and Bullock followed his advice so closely that his images often resembled Weston's. He is best known for realistic images that are meant to be viewed as "equivalents," or visual metaphors (e.g., the passing of time, the inevitability of death).
