Abstract
Photographic direct-positive materials are described which comprise in admixture in a single layer or in superposed layers a monodispersed direct-positive emulsion and a heterodispersed direct-positive emulsion. By the use of both types of emulsions it is possible to obtain reduced contrast and good detail rendering in the high-light areas.
