摘要
The invention is accomplished by forming balanced cyan, magenta, and yellow coupler and emulsion mixes. There is at least one layer in which silver halide emulsion has been sensitized to blue light or silver halide emulsion sensitive to green light. Regardless of the color sensitivity of the silver halide layer that contains silver contains a mix of cyan, magenta, and yellow dye-forming couplers. Further, in order to have a black-and-white image that has a lightness such as observed by the human eye in a scene, it is preferred that the ratios of red sensitive emulsion to green sensitive emulsion to blue sensitive emulsion in the photographic element is about 2:3:1.
