Description

Used in Raw IFD of DNG files.

LinearizationTable describes a lookup table that maps stored values into linear values. This tag is typically used to increase compression ratios by storing the raw data in a non-linear, more visually uniform space with fewer total encoding levels.

If SamplesPerPixel is not equal to one, this single table applies to all the samples for each pixel.
