Abstract
The invention relates to a photographic element comprising a support and at least three color records comprising at least three light sensitive layers and at least two interlayers, wherein the light sensitive layers include cyan, magenta, or yellow dye-forming coupler, the light sensitive layers include silver halide grains comprising greater than 90% silver chloride, scavengers are included in the interlayers, the ratio of the total level of scavenger to the total level of coupler is from 0.15 to 0.50, the ratio of the total level of scavenger to the total level of silver is from 0.05 to 0.15, and the reciprocity characteristics of the silver halide grains are such that for a separation exposure of 1 microsecond and 0.4 seconds, upon development, the difference in maximum density is 10% or less and a method for processing the element comprising color developing the element for less than 30 seconds.
