A nude study in autochrome by Arnold Genthe. Autochrome was patented by the Lumière brothers in 1903 and became the dominant colour photography process for over two decades. It used dyed potato starch in its plates to provide colour. Because of additional filters necessary for the process, it required longer exposure than black-and-white plates.
