High performance, high contrast radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films having at least two silver halide emulsions on each side of a film support, and the emulsion closest to the film support on each side includes chemistry to control crossover and has higher photographic speeds than the other emulsions. In addition, the films can be rapidly processed to provide the desired image having visually adaptive contrast, i.e. the upper scale contrast is at least 1.7 times the lower scale contrast. Thus, dense objects can be better seen at the higher densities of the radiographic image without any adverse sensitometric changes in the lower scale densities. These films are useful for general purpose, high contrast radiographic imaging.
