jan 1, 1907 - The autochrome was invented by the lumiere brothers

Description:

The Lumières’ key ingredient was potato starch. The process was called autochrome and involved covering a glass plate with a thin wash of tiny potato starch grains dyed red, green, and blue - creating a filter. When the plate was flipped and exposed to light, the resulting image could be developed.

The first natural colour photograph to appear in National Geographic magazine was an autochrome depicting a flower garden in Belgium, published in 1914.
