Abstract: A process for producing three dimensional pictures which begins with a photograph. A mold is first sculptured by affixing a picture of the image in the photograph to a pliable mass such as clay, and then sculpturing the mass using the picture as a guide as to where to place elevations and depressions. Next, the photograph is subjected to steps which result in the removal of the backing, and the lamination of the photograph with the backing removed in plastic. Next a "Vacu-Form" machine is used to heat soften the laminated photograph and then suction pull the combination over the mold. The mold and the photograph are alligned during the pulling step and the result is that the photograph takes on a third dimension which has eleveation and depressions placed as they should be placed by reference to the image in the photograph. The result is an article which retains a third dimension with no need of any supporting materials. Optional steps involve mounting the three dimensional picture in a display device, or combining a number of the three dimensional pictures so as to form an object. As well, cosmetic materials can be applied to the three dimensional picture to improve the appearance.
