A process of compositing two or more separate images comprising: (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 red light, green light, and blue light sensitive color records, and at least one distributed red light absorbing compound in an amount 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 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.

Color photographic silver halide negative imaging material and process

A color photographic silver halide negative working duplicating element comprising a support bearing, in order from the support, at least one red-sensitive photographic silver halide emulsion layer package comprising at least one cyan image-dye forming coupler that is capable upon exposure and processing of forming a cyan image dye that absorbs in the range of the original image; at least one green-sensitive photographic silver halide emulsion layer package comprising at least one magenta image-dye forming coupler that is capable, upon exposure and processing, of forming a magenta image dye that absorbs in the range of the original image; and at least one blue-sensitive photographic silver halide emulsion layer package comprising at least one yellow image-dye forming coupler that is capable upon exposure and processing of forming a yellow image dye that absorbs in the range of the original image. The silver halide particles in the fastest blue sensitive layer have an equivalent spherical diameter no greater than 0.3 microns, while in the remainder of the layers the silver halide particles have an equivalent spherical diameter of no greater than 0.23 microns. The silver level in the fastest blue sensitive layer is no greater than 30 mg/square foot. A sufficient red absorber is present so that the red record MTF(12) is at least 95% of the green record MTF(12) and the red record F50 is no more than 6/mm less than the green record F50.
