Color LUT
A Look-Up Table that maps input color values to output color values, enabling instant application of complex color transformations.
A Color LUT (Look-Up Table) is a mathematical table that transforms one set of colors to another. 3D LUTs map every possible RGB input to a specific RGB output, enabling complex color transformations that would require dozens of individual adjustments. LUTs are the industry standard for color grading in photography, film, and video. A single .cube or .3dl file can transform flat, log-format footage into a cinematic look. Creative LUTs replicate film stocks, specific movies' color palettes, or signature editing styles. Technical LUTs handle color space conversions (Rec.709 to DCI-P3). In photo editing, LUTs work similarly to presets but operate at a more fundamental level, transforming the entire color pipeline rather than adjusting individual sliders.
