(57) A photosensitive element comprising a support and radiation-sensitive imaging means
capable of undergoing as a function of at least one of photographic exposure and processing
a change in the optical density or mobility of the imaging means is disclosed. The
support provides a nonplanar surface pattern forming an array, and the imaging means
includes a high aspect ratio tabular grain silver halide emulsion coprised of a dispersing
medium and silver halide grains, wherein tabular silver halide grains having a thickness
of less than 0.5 micron and a diameter of at least 0.6 micron have an average aspect
ratio of greater than 8:1 and account for at least 50 percent of the total projected
area of the silver halide grains.
