The Autochrome process was developed by the Lumière brothers in 1903. The technique was based on a composite of black and white emulsions passed through a series of color filters (red, blue and green) designed based on potato starch. The first photograph were taken in Morocco in 1907. The process was a such a success such that the Lumière factories soon produced up to 6000 plates per day. This technique was abandoned in 1935 in favor of newer process techniques.
