Gumroad – fsorvin – Autochrome LUTs Free Download

This LUT set simulates the Lumière brothers beautiful Autochrome early colour film process. Put into production in 1907, Autochrome was an additive colour photographic and later attempted motion picture process that used a mosaic of coloured potato starch grains layered over monochromatic glass plate emulsion to both filter and colour the recorded image.

Autochromes were not commonly printed (unless transferred for mass printing, like in National Geographic), but were more commonly viewed in a stereoscope or with a diascope, a box that used daylight, a mirror and a diffusion plate to illuminate the camera original plate from behind.

Autochrome’s mosaic, dyed potato starch grains of red-orange, green and blue-violet, were so small as to be invisible but blended together to form the impression of colour, much like an RGB display does now. Visible were the clumps formed by the imprecise spread of grains on the colour mosaic. This LUT cannot simulate the clumping. If you want to simulatate it, add in a noise layer before the LUT in your image chain.
