Because of the increased need for the control of motion-picture printers used for printing color films, a simple barrier-cell type of light meter was designed for use on release printers. The meter has very good stability and linearity of response. Its sensitivity is very adequate for the intensity levels encountered in release printers. The probe unit contains a filter magazine that permits rapid reading through red, green and blue filters. It was designed to give photocell response which closely approximates the responses of the three sensitive layers of Eastman Color Print Film, Type 5382.
