Toronto. You may have never heard of a Frenchman of the name, “Louis Arthur Ducos du Hauron“, but by 1870, after Maxwell’s ribbon experiment, he had devised most of the ways humans could create colour images.
Unfortunately, this was well before technology caught up and made his ideas practical.
The colour photo at left used his ideas. It is an Autochrome c1910. Autochrome’s were created by the French Lumière Brothers.
The late Brian Coe in his “Colour Photography” said, ” … in his writings, [he] anticipated almost all of the practical methods of colour photography”. This was at a time when photographic media was blue light sensitive and any light of a lower wave length was blank on the ‘negative’, and black in the print.
