Physical Aspects
Paper prints were the positive opaque copies of their transparent film negative source. Just like film wound on a film core, the paper print was also tightly wound in the same way. Most accounts of the paper prints collection never mention the chemical composition of the photographs, but archivists at Ohio State University who received one of the restoration printers used for the conversion project refer to these photographic prints as existing on bromide photographic paper. No specifications could be found on the composition of bromide paper of the time, but one manufacturer today is Kentmere. Their bromide paper “features a conventional double weight fiber-base, coated with a neutral tone bromide emulsion…Glossy unglazed surface only. The double weight paper is approximately 276 g/m² and a thickness of approximately 260 μm.” Photos of the paper on cores have a density that look very much like the films would, although there are no specifications on film of the time. Motion picture film was not standardized in the early years, and therefore, neither were their paper copies.
