2 color, single strip |
Single strip of film was exposed with pairs of images by means of a beam-splitter prism. One of the pairs of images was exposed through a red filter and one through a green filter. The resulting negative was used to produce both prints consisting of two strips cemented together, and, later in the history of the process, two color dye transfer prints. |
