The War To End All Wars Shown As Never Before
Nor were the powers at war in 1918 locked into the obsessive/compulsive overdocumentation in both pictures and text that they would be in World War II.
Not only are these very good pictures, they are also in color. The Lumiere brothers, inventors of the movie camera, also perfected one of the first viable color photgraphy processes, the Lumiere Autochrome. These were glass slides with the color dyes imbedded in grains of starch overtop of the light sensitive emulsion.
These autochromes were made by the French, probably by a professional, from the look of them, for some official archive, a commonplace cultural use of photography in France, dating back to the mid-19th century, and the earliest days of the medium.
