Abstract

This paper is the result of two years of work with Agfa film (50x60cm) for pseudo-color reflection shadowgrams using an 18 milliwatt laser on a sand table. The author describes the procedures and equipment used in producing these holograms. This system empowers the individual artist/holographer to produce work often thought to be available only to teams working in large labs. The paper focuses primarily on the gelatine lamination technique used by the author to hold film to glass. The pros and cons of other film holding techniques are mentioned. Special handling of the film during pre-swelling and squeegeeing is described as is the exposure and development scheme necessary for low power lasers. The camera geometry for reflection shadowgrams is detailed as is the equipment (plate holders, mirrors) needed for making 50x50cm images on a sand table.
