A New Automatic Sensitometer

The ever increasing demand for higher technical quality of motion-picture films has forced the film laboratories into ever more rigid process control and monitoring. One phase of monitoring film stock and processing machines consists of processing film strips exposed to known light levels. In a large laboratory several of these sensitized strips are processed in one day. Since these strips will be a standard for the entire lab, the accuracy with which they are produced is of ultimate importance. Secondly, when a large number of strips are used, the means of producing these strips should be fairly automatic. Design specifications and manufacture of a Type 2B sensitometer which is capable of producing such strips are described.
