Graininess in Motion Picture Negatives and Positives
An instrument which measures the graininess of a photographic material is described. It is shown by the aid of photomicrographs that the readings of the instrument represent the true graininess as understood by the photographer. The instrument has been used in an investigation of the various steps in the preparation of a motion picture positive to determine the conditions for minimum graininess in the finished print. The exposure of the negative is found to have considerable influence on the graininess of the print, developing conditions being relatively unimportant. An explanation of the excessive graininess which sometimes occurs is given.
