Abstract

412,096. Colour photography and kinematography. DOLGORUKI, E. SANDERS-, 1000, Church Avenue, Brooklyn, New York, U.S.A. Nov. 3, 1933, No. 30576. [Class 98 (ii).] In the process in which separate colour-record negatives are taken, the settings of the taking camera are determined by the indications of an electrical measuring instrument in the circuit of a light-sensitive cell which is exposed to the light through filters corresponding to the taking filters. Separate cells and instruments for each colour component may be used or, as shown, the cell 12 may be exposed through the filters 81, 8<2>, 8<3> in succession, the filters being carried on a rotary carrier. A battery may be provided in the circuit, or the self-generating type of cell used. To control the exposure in a camera having three lenses associated with filters, a rotary shutter is provided having three annular slots, the lengths of which are adjusted by movable cover plates.
