FIELD: photographic processes. SUBSTANCE: method involves two color-separation negatives using positive chromium salt processes on papers with removable layer or electrophotography. In the first case, carbo process, oil method, hydrotype method, etc. are used to color bright places on negative, and pinatype process to color dark places on negative. When using electrophotography, bright places on negative are colored with one polarity sign and dark places with the opposite. Two missing colors are formed from these thus obtained colors. EFFECT: improved procedure. |
