Abstract

175,373. Warner, F. M. Nov. 10, 1920. Drawings to Specification. Colour photography.-Positives from combined screen-plate negatives are produced by printing the screen-plate negative on to a support coated with panchromatic emulsion and subsequently registering a viewing-screen which is identical with, or a copy of, the negative screen. The conditions under which the positive is printed must be balanced as regards light and emulsion with those under which the negative is taken, either by the use of compensating-filters or by adjusting the colour-sensitiveness of the emulsion.
