A Modern Approach to HDR Color Timing

HDR displays and projectors pose new challenges for mastering content while still supporting traditional TVs and cinema projectors. The traditional workflow, taking images straight from the camera and adjusting color correction knobs until they look good on a display, is no longer practical. Nor can a single color appearance LUT give the best results on HDR and SDR displays. Color correction and creative grading must be based on comprehensive color management and color appearance modeling. Color grading controls based on scene radiance and human vision can balance images more naturally, and impart creative looks that translate easily to HDR and conventional displays in varying viewing conditions. This paper summarizes the fundamental color science framework needed for color space conversions between cameras, grading tools, and displays; and proposes a core set of perceptually based color correction tools.
