Part II: Telefilm Density and Exposure Control
A system for making 16mm film for television broadcasting is called Teledexicon. It is based on the establishment and maintenance of standardized characteristics for telecine reproduction, the film process and the printing operation. It permits relatively inexperienced personnel to achieve high accuracy in negative exposure and predictable TV gray scale from release prints. Live TV studio output and telecine film output may be made to have matched gray-scale characteristics. Exposure is determined by measuring scene element luminances with a spot photometer and relating it to telecine video voltage with simple rotary calculators. Teledexicon permits accurate control and prediction of gray scale, lighting key and mood while shooting is in progress and before the film is processed. Objective measuring techniques are used throughout.
