Autochrome process
Definition
The first industrial color photography process on glass plates, invented by the Lumière brothers in 1903 and marketed starting in 1907, based on the use of a mosaic of microscopic potato starch grains dyed in three primary colors (red-orange, green, and violet) acting as structural color filters. The result was a unique positive image, characterized by warm, pastel tones resembling Impressionist paintings.
