ABSTRACT:
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.
