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.
Claims6
A process for the production of a painted reproduction on glass of a subject, which comprises photographing the subject using a fine grain medium contrast panchromatic photographic film, processing the film to produce a low-contrast image, projecting the image on the film as a black image on to a photographic glass plate coated with a slow, blue-sensitive high contrast orthochromatic emulsion having very fine grain and very high resolution, bleaching out the black image produced on said glass plate and toning said image in a colour other than black, coating the emulsion side of the glass plate with a clear varnish, and colouring the image on the glass plate with paint applied to the varnish coating in two stages, paint first being applied to detailed parts of the image in substantially exact conformity with the margins of the detail and paint thereafter being applied to remaining parts of the image after drying the paint applied to the detail parts, the paint being applied to said remaining image parts in such manner that small zones free of paint exist between adjacent painted areas.
