LUTs: A Primer A "LUT", or "lookup table", is an array of preselected values used in movie color-correction to map colors from the original input footage to the desired colors in the final output. Color correction is performed by looking up input colors and assigning them new RGB values based on the data in the table. A lookup table that treats each of the red, green, and blue channels separately is a "1D LUT", which cannot be used to correct saturation or hue. Such corrections require a "3D LUT", in which each combined RGB value maps to a single combined value in the table. 3

output. Color correction is performed by looking up input

A lookup table that treats each of the red, green, and blue

combined value in the table.
