ELECTRONIC MASKING FOR TELECINE: a review of masking for positive and negative film

摘要

This Report reviews the theory of electronic masking for telecine for use with positive print, negative and reversal films. Practical results are discussed and it is con¬cluded that satisfactory results can be obtained for positive print and negative films from the theory of electronic dye masking. Reversal films, because of the magnitude of their interimage effects do not give good results with this type of masking. A satisfactory mask was calculated for reversal film from measurements of the response of a typical telecine to samples of known exposure.
