Additive four-color: beam splitter and filters, four images on 35mm black and white film.
For this four-color process, the light beam was decomposed into four parts, each of which simultaneously exposed an area equal to one quarter of the 35mm frame of a black and white negative. This was obtained optically by placing a diaphragm and a ...
