Overview
LUTs contain predefined color mappings, but not every possible color value is stored. Interpolation determines how intermediate colors are calculated between existing data points.
Types
Common interpolation methods include nearest-neighbor, trilinear, and tetrahedral interpolation. Higher-quality methods produce smoother gradients.
Impact
Poor interpolation can cause banding or color artifacts, while advanced interpolation produces natural tonal transitions.
Professional Relevance
High-end workflows prefer tetrahedral interpolation because it preserves color accuracy.
