Bermpohl Naturfarbenkamera

wood construction for bellows and three film plates

The Naturfarbenkamera (natural colors camera) was one of the typical three-color cameras made by Bermpohl & Co., Berlin. A system of semipermeable mirrors divided the incoming light into three light bundles, each projecting the same image on one of the three film plates. The color filters in front of each film plates made the black-and-white exposures usable as originals for three-color printing.
