Show a clip as if it had been recorded on an Autochrome plate. Color comes from a mosaic of tiny dyed grains, which gives soft, pointillist color with the dreamy look of early 20th-century photographs.
Grain, saturation, and fading
Grain Size sets the scale of the starch mosaic: small grains read as photographic, large grains as visible dots. Color Saturation sets the strength of the dyes, and Fading lifts and softens the tones as on an aged plate.
Motion
The grain is a fixed structure, so motion reads as the scene moving behind the plate. Slow, gentle footage such as gardens, portraits, and still water fits the period look.
