Abstract: Consistency in negative printing values is one of the most desirable factors in modern cinematography. Photoelectric light-measuring devices help the cinematographer maintain such consistency to a far greater degree than is possible otherwise. Several requirements in these devices must he recognized, among which are freedom from error and photocell fatigue, changes in humidity or temperature, and the like, and good uniformity. While these requirements are not wholly met in existing meters, it has been found possible to use such meters to advantage. Coördination is effected by use of a special, portable testing unit of the photometer type. Further developments should include complete accepiance of strict time-and-temperature methods of negative development und some form of automatic, photoelectric-cell-controlled print-timing. This would remove all variables from the processing problem, and leave the responsibility for results solely in the hands of the cinematographer.
