    摘要: A process of compositing two or more separate images is disclosed comprising the steps of: (a) imagewise exposing a color negative photographic recording material to a subject in front of a uniformly colored screen background, wherein the photographic recording material comprises a support bearing a red light sensitive color record comprising at least one red light sensitive silver halide emulsion and at least one cyan dye forming image coupler, a green light sensitive color record comprising at least one green light sensitive silver halide emulsion and at least one magenta dye forming image coupler, and a blue light sensitive color record comprising at least one blue light sensitive silver halide emulsion and at least one yellow dye forming image dye forming coupler, and further comprises at least one distributed red light absorbing compound, wherein the quantity of distributed red light absorbing compound is such as to reduce the sensitivity of the red light sensitive color record by at least 40%, and the light sensitivities of the green light sensitive color record and the blue light sensitive color record are each reduced by less than 20% by the presence of any distributed green light absorbing compounds or blue light absorbing compounds, (b) forming a color negative image of the subject and screen background by developing the exposed photographic material with a color developing agent, (c) separating the subject image of the color negative from the screen background image, and (d) compositing the separated subject image with a second image. Photographic elements for use in such process are also disclosed. The invention eliminates or substantially reduces red record fringe problems without significantly effecting granularity in the blue and green color records. The use of distributed red light absorbing compounds that may move between layers during formation of the photographic element or its later storage in accordance with preferred embodiments allows the introduction of the light absorbing compound into a single location of the multilayer photographic recording material during manufacture, simplifying this labor intensive process. In preferred embodiments, the invention allows almost full advantage to be taken of the high speed of tabular grains with markedly improved sharpness. In preferred embodiments, the invention provides an EI 200 speed negative with desirable granularity and considerable reduction of the red fringe problem.
