| The Autochrome is an early color photography process. Patented in 1903 by the Lumière brothers in France and first marketed in 1907, it remained the principal color photography process available until it was superseded by the advent of color film during the mid 1930s. Autochrome is an additive color 'screen-plate' process: the medium contains a glass plate, overlaying random mosaic of microscopic grains of potato starch, with lampblack filling the space between grains, and an impermeable black-and-white, panchromatic silver halide emulsion. The grains are a mixture of those dyed orange, green and violet, which act as color filters. The plate is processed as a slide - that is, the plate is first developed to a negative image and then reversed to a positive image - and the starch grains remain in alignment with the emulsion after processing in order to allow the colors to be seen properly. |
