Description
Used in IFD 0 of DNG files.
The DNG color model documents a transform between camera colors and CIE XYZ values. This tag describes the colorimetric reference for the CIE XYZ values.
0 = The XYZ values are scene-referred.
1 = The XYZ values are output-referred, using the ICC profile perceptual dynamic range.
This tag allows output-referred data to be stored in DNG files and still processed correctly by DNG readers.
