Three-dimensional lookup table mapping input color values to output values for color grading and display calibration.
Technical Details
I use 3D LUTs daily for on-set monitoring to give the director and myself a realistic preview of the final look. They are particularly indispensable for Log footage, as the raw image appears extremely flat and low in contrast – the LUT immediately shows us how the scene will appear after color correction.
Practical Application
For me, 3D LUTs are a creative tool that helps me define and communicate the visual mood of my film already on set. I can test different looks and, together with the cinematographer and colorist, develop the perfect visual style that optimally supports my story. 3D LUTs save me time and money in post-production, as they create an efficient workflow between shooting and color correction. By using standardized LUTs, alignment loops and correction passes are reduced, which significantly lowers costs in color grading and makes schedules more predictable.
