ABSTRACT:
A procedure is disclosed for the production of paintings on glass, the subjects of the paintings being, for example, original paintings, engravings, lithographs and like articles whose appeal is primarily aesthetic. A low-contrast image of the subject is first produced using a photographic film, preferably a fine-grain medium contrast panchromatic film, the image is projected on to a photographic glass plate which is preferably coated with a slow, blue-sensitive high contrast orthochromatic emulsion having very fine grain and very high resolution, a clear varnish is applied to the emulsion side of the glass plate and the image is colored by application of paint to the varnish coating.
