Abstract
454,163. Colour photography. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. March 27, 1935, No. 9570. Convention date, April 21, 1934. [Class 98 (ii)] A photographic or kinematographic colour film of the subtractive type is printed by projection on to a lenticular film in one exposure affecting all the colours to be reproduced, and the lenticular film is developed to a positive by the reversal process. The original may be 35 mm. film and the copy 16 mm. film. As shown in Fig. 1, a film 1 of the subtractive type is projected by a lamp 4, condenser 5 and projection lens 6 on to a screen 3, the image la on which is taken on a lenticular film 2 by an objective 8 and colour filter 7. The lenticular film 2 is developed by the reversal process. As shown in Fig. 2, the film 1, illuminated by a system comprising a lamp 4 and spaced condensers 15 between which is a ground glass diffuser 20, is printed directly on to the lenticular film 2 through the colour filter 7 by objectives 18. The concave lens 21 provides the correct relationship between the filter 7 and film 2. The films may bear sound records. Specification 322,231, [Class 98 (ii)], is referred to.
