Dufaycolor is an early British additive colour photographic film process, introduced for motion picture use in 1932 and for still photography in 1935. It was derived from Louis Dufay’s Dioptichrome plates, a glass-based product for colour still photography introduced in France in 1909.
Both Dioptichrome and Dufaycolor worked on the same principles as the Autochrome process, but achieved their results using a layer of tiny colour filter elements arrayed in a regular geometric pattern, unlike the Autochrome’s random array of coloured starch grains.
However, the manufacture of Dufaycolor film ended in the late 1950s.
Here below is a rare and amazing collection of dufaycolor photos from The History of Photography Archive that shows daily life of Belgium in 1936.
