El Autocromo fue un procedimiento fotográfico que conseguía reproducir colores gracias al uso de almidón de patata, aunque requería paciencia para su elaboración porque era un proceso largo y artesanal. Patentado en 1903 por los hermanos Lumiere y comercializado en 1907, estuvo vigente hasta 1935. Se pueden ver algunos ejemplos en Belgium Autochromes, The Wonderful World of Albert Khan y Mediathèque de l'Architecture et du Patrimonie.
The Autochrome was a photographic transparency film created in 1903 by Lumiére brothers and patented in 1906 in America, sold in 1907. Like other techniques of the time, it employed the additive method, recording a scene as separate black and white images representing red, green and blue, and then reconstituting color with the help of filters. To do this on a single plate, the Lumiéres dusted it with millions of microscopic transparent grains of potato starch that they had dyed red, green and blue. This screen of grains worked as a light filter to interpret the scene when the light passed through them exposing a panchromatic B&W emulsion. It was used until 1935.

"Lo que convierte a la fotografía en un invento extraño -de imprevisibles consecuencias- es que su materia prima son la luz y el tiempo.", John Berger. "What makes photography a strange invention - with unforeseeable consequences - is that its primary raw materials are light and time."
