Description
Used in IFD 0 or Camera Profile IFD of DNG files.
This tag specifies the number of input samples in each dimension of the hue/saturation/value mapping tables, respectively. These values are next referred to as HueDivisions, SaturationDivisions, and ValueDivisions.
The data for these tables are stored in ProfileHueSatMapData1 and ProfileHueSatMapData2 tags. Allowed values include the following:
HueDivisions >= 1
SaturationDivisions >= 2
ValueDivisions >=1
The most common case has ValueDivisions equal to 1, so only hue and saturation are used as inputs to the mapping table.
