Abstract: 242,727. Campbell, K. Aug. 20, 1924. Colour photography, screen plates and processes for.-A multi-colour screen material for coating upon sensitized plates or films for photographic or kinematographic use is produced by bleaching fine spores or pollen, dyeing equal quantities thereof respectively in three primary colours, mixing these together when dry, and emulsifying the mixture with gelatin or celluloid solution to form a liquid. In an example described spores or pollen of L. Clavatum are bleached in acidified hydrogen peroxide, washed, and air-dried, all at a temperature not exceeding 145‹ F. The powder is pulverized, and divided into three equal parts which are dyed respectively with a mono.spectrum yellow such as naphthol yellow, a mono-spectrum red, such as erythrosine and a mono-spectrum blue such as methylene blue in alcoholic solution, and dried. The three powders are mixed together, and mixed with liquid gelatin or celluloid, for example in the proportions of two ounces of powder to ten ounces of liquid. The sensitive material which carries a high-speed panchromatic emulsion, is coated by immersion in a bath of the screen material so prepared, and is passed first between steel rollers to reduce the coating to a single layer of coloured particles, and then over an absorbent roller to remove the coloured coating from the rear side of the film only. Negatives produced by exposing the material in a camera are either reversed, or are printed upon similar material, to produce a positive.

A reflex camera has a supplementary attachment device comprising a semi-transparent mirror by means of which another image (from a picture, or a screen) can be reflected into the normal light path. The invention is shown as applied to a twin lens (12, 12a) reflex camera. The object or original being photographed may be carried on a support 26. The supplementary attachment device 1, which includes a mirror 3 and a semi-transparent mirror 2, is attached as at 4 to the camera 20. Light from the object at 26 is partly transmitted through mirror 2, and so through the exposure lens 12 to the light-sensitive film 22, and partly reflected from mirror 2. The reflected light is further reflected by mirror 3 to pass through the viewing lens 12a to the viewfinder. A transverse section 6 of the device 1 houses a lamp 16 and a picture holder 8. The image of the picture or transparency in holder 8 is partially reflected from mirror 2 into the light path from the object at 26, and so the two images appear superimposed on the film 22, and also in the viewfinder. As an example, the object at 26 may be the screen of an oscillograph tube, and the superimposed image from holder 8 a measuring grid. Alternatively the superimposed image may be a further oscillograph screen.
