Problems of Small Laboratory Operation

John I. Newell

This paper deals with a small laboratory's solution of problems of duplication and processing in an essentially low-volume area of the United States. Specifically, the paper describes one method of making black-and-white reversal release prints of high quality, and another method of reversal duplication utilizing low-cost, positive-type emulsions. The paper also discusses 16mm negative developing and comparative results achieved through the use of Hoffman PR-400 developer.
