Gamma & Density Log Chart System

The Gamma & Density Co. Log Chart System is a modular and customizable chart system to provide cinematographers with a benchmark for color and exposure, while providing crucial information to DITs and Post-Production about how the Log or RAW images should be interpreted.

Similar to the ways a film negative can be processed and interpreted, the digital image is also subject to processing and interpretation through easily accessible tools. Color charts, from the beginning, have been a method of communication between the Cinematographer and Post-Production (telecine, editorial, DI, etc.). This communication helped to ensure the creative intentions of the Cinematographer is present on footage for dailies and into the final color grade.

As new digital cameras change the way footage is captured, digital cinematography is no longer "what you see, is what you get". The image seen on monitors during production is rarely the same image that is being captured. This influx of images captured with Log Gamma Curves and RAW capture create new possibilities for image interpretation, and further reinforce the necessity for a consistent color and exposure benchmark from which DITs and other members of post-production can realize the creative intentions of the Cinematographer.
