Abstract

For electronic image recording in one or more colors a photographic recording material comprising in at least one layer photo-sensitive silver halide and a compound capable of luminescence is image-wise exposed and developed to produce a latent luminescence image. The image information contained in the latent luminescence image is scanned photoselectively by a luminescence spectroscopic process and is recoded electronically in the form of monochromatic luminescence signals. The process provides images in one or more colors and is highly sensitive. Recording materials of extremely low silver application can be used.
