The first time that colour was used in photography
Lumiere brothers developed a Revolutionary process involving the colour in photography. This process is called the Autochrome. The Lumiere brothers discovered it in 1903 and it was marketed for the public in 1907. For this technique, it was necessary to use a photographic glass plate. The colours were obtained by mixing grain starch potato and primary colours (red, green, blue) then sprinkling everything on a coated glass plate with a sticky substance. The plate is then covered with a black powder, then varnished and coated with a sensitized emulsion and exposed in the dark room. After the development, the resulting image is a transparent positive.
Each Autochrome is a single image, and was made to be viewed by projection.
This process was a very important discovery, but what made the Lumiere brothers famous was the invention of the Cinematograph in 1895, the first cinematic machine in history!
