The LUT adjustment emulates image colors used in a variety of media platforms.
A LUT (look-up table) remaps pixel color values based on a defined XYZ matrix. This allows you to quickly replicate the appearance of various types of media, such as reproducing the cold, blue tone attributed to science fiction and horror movies.
The look up table is stored within a file previously exported from Affinity Photo or other applications (e.g., video packages). Alternatively, it can be inferred by comparing images.
