摘要： A method for obtaining direct positive images wherein a photographic material having a support and at least two silver halide emulsion layers coated thereon, each layer having a different spectral sensitivity, said emulsions being of the internal latent image type and containing unfogged silver halide crystals, is imagewise exposed and then subjected to an overall area exposure prior to or during the development thereof to form the image. The overall area exposure is such that the photographic intensity ratios between various layers are not more than 6 and the intensity of such overall exposure has a value between light intensities which give 0.8 times the maximum image density of the particular emulsion layer and 10 times that light intensity value. The photographic intensity ratio is the ratio between photographic intensities of two emulsion layers and the photographic intensity is the reciprocal of the intensity value that corresponds to an image density which is 50% of the maximum when an imagewise-unexposed internal latent type image silver halide emulsion layer is subjected to light-intensity scale exposure and the density of the image formed is measured with a light which corresponds to the absorption maximum of the image.
