Color Processing for Digital Cinema 2: Explanation of the Constants 4095 and 52.37, the White Points, and the Black

Abstract

This series of articles on the color processing for digital cinema is based on the Engineering Guideline, SMPTE 432–1. The DC28 committee thought the information in that guideline would be more widely available if it were published as a series of articles in the SMPTE Journal. This second article in the series describes the reasons for choosing the constants 4095 and 52.37 in the Digital Cinema Distribution Master (DCDM) encoding and decoding equations and discusses white and black points.
