Verfahren zur Herstellung dichtemaessig standardisierter Kopien

摘要

Positive photographic images of substantially the same high density and substantially the same low density are produced from negatives having wide range of densities but substantially the same shadow density by printing the negatives on printing material that prints with different contrast when exposed to different colors, but produces substantially the same high density for the same exposure times, and adjusting the exposure proportion to both colors to bring the low density to substantially the same low level.
