Abstract
Photographic process, in which a substrate comprising a plurality of superimposed layers of photochromic materials sensitive to different light wavelengths is provided. The object to be photographed is scanned and a digital file defining the image of the object is generated from the scanning. A plurality of sources of laser light having different wavelengths, each of which is the wavelength to which one of the photochromic materials is sensitive is provided and the layers of photochromic materials are irradiated by means of the laser beams produced by the sources, according to a program determined by the digital file, whereby to develop in each pixel of the substrate the color that it has in the image. The colors thus generated in the pixels of the substrate layers; and the background areas of the substrate layers are set.
