Abstract
In 1926, Capstaff and Seymour1 published a paper giving directions for making duplicate negatives using a new film manufactured specifically for that purpose. Good quality and tone reproduction were possible by this method although the graininess of exhibition prints was not entirely satisfactory. Since then, improved films have been available, and the present paper contains a description of the tests performed during a search for the most satisfactory sensitive materials and processing technic. The experiments showed that in order to minimize graininess, the master positive must be developed to a relatively high gamma (1.85) in a positive developer, and the duplicate negative to a correspondingly low gamma (0.55 or less). There are also given data which explain why the high gamma master positive in conjunction with a low gamma duplicate negative gives the most satisfactory graininess.
