Abstract

212,674. Forbes, Sir C. S. Dec. 28, 1922. Colour photography; films.-A roll film spool or cartridge comprises a front film sensitized mainly for one particular colour (e.g. green), and a rear separable opaque strip sensitized mainly for another colour (e.g. red). The rear strip may be the ordinary backing strip of a roll film. Ordinary prints may be obtained from the front film discarding the second image, or for colour work a filter may be used filtering out ultra-violet rays and the two colour records used to obtain colour prints by any known process. The rear film may be developed as a positive. Specifications 5641/08, 873/15, and 14511/15 are referred to.
