- Abstract
- The requirements are outlined for a negative-positive laboratory process to obtain predictable waveforms at the output of a calibrated telecine camera chain for measured luminance of scene elements. By utilizing the inherent reproducibility of the photographic process, a constant density and density difference system may be established utilizing conventional processing and printing equipment and materials. Techniques are described for controlling the output of processing machines of the Houston Fearless type, particularly applicable to smaller laboratories associated with television broadcasting agencies. Statistical analysis of sensitometric control strips is employed to evaluate processing reproducibility. Chemical analysis of bromide content provides sufficient information to maintain image-forming conditions, when the replenishers for negative and positive developers have the same composition as the starting solutions (before the addition of bromide) and are added directly to processing machine tanks. Tolerances that may be readily achieved in the practical operation of a system of this type are given.
