The Horst process saw a brief flurry of activity in Britain and Europe in the early 1930's. The camera recorded all three color records within the confines of a conventional 35mm frame, which made for a rather small image but registration was maintained. Beam splitters split the spectrum to place the images on a black & white film. The Horst process benefitted from having only a single camera lens. The projector used three lenses to merge (with varying success) the three images after they passed through their respective filters. While the color may have been fairly accurate, it suffered from excessive grain and a dim projected image, a trait of all additive color processes. Convergence of the projected image was at the mercy of the projectionist. The subject matter in these two examples is unknown..
