Endowed with great technical mastery and using almost exclusively black and white photography, Sugimoto uses the unique quality of long exposure photography to address themes of history, memory, and time. Although he considers the photographic medium "a system for saving memories," the artist also provides us with a vision of how photography can alter reality and record almost imperceptible traces. The exploration of the empirical and the metaphysical is at the center of his work, which functions as visual memory rather than documentation. The Dioramas, Seascapes, and Theaters series are famous. This work "U.A. Walker, New York 1978" belongs to the latter. Sugimoto photographed old American movie theaters using a 4 x 5 camera with tripod, keeping the lens open for the entire duration of the film, with the projector being the only light source. The luminescent screen in the center of the composition, the architectural details, and the seats are recorded in the image, with light being Sugimoto's instrument for revealing time.
