35-mm Planetary Cameras (Top-Light) û Procedures for Determining Illumination Uniformity of Microfilming Engineering Drawings (includes supplements)
Specifies the minimum test target elements and their criteria to be used in determining the uniformity of illumination on the copy board of a 35-mm planetary camera. The layout of the test target and the procedures to be followed in obtaining a uniform density of microfilm images from a planetary camera are established to assist in the achievement of high-quality, first-generation, silver-gelatin microfilm of engineering drawings.
