A unique colored transparent image on glass meant to be viewed against a light or projected; the first colored photographs; prepared plates for this process were manufactured between 1907 and about 1940 by the Lumire brothers who had invented the process in 1904.
A color photograph invented by Louis Lumiere in 1903, using a glass plate covered with grains of starch dyed in three colors to act as filters, then a silver bromide emulsion (colorplate 176).
early commercial color photography process in which the principles of additive color synthesis were applied.
A unique, colored transparent image on glass, intended to be viewed by being held up to light or projected. A glass plate is coated with a varnish holding tiny grains of potato starch dyed red, green and blue-violet and then coated again with a light sensitive gelatin bromide solution.
A type of positive color transparency using starch grains dyed to the primary colors of red, blue and green. Introduced by the Lumiere brothers as the first successful commercial color process, it was introduced in 1907 and is considered the first advanced color process to gain popularity.
A practical, additive photo process perfected in 1907 using a glass plate dusted with transparent grains of potato starch dyed red, green and blue. These starch grains act as tiny color filters, allowing light to affect a piece of film sandwiched behind the glass plate. Film is then reverse processed into a positive transparency. Graininess and spots often appear in the finished image because starch grains could not be evenly mixed.
