TIFF Tag CameraCalibration2
Used in IFD 0 of DNG files.
CameraCalibration2 defines a calibration matrix that transforms reference camera native space values to individual camera native space values under the second calibration illuminant. The matrix is stored in row scan order.
This matrix is stored separately from the matrix specified by the ColorMatrix2 tag to allow raw converters to swap in replacement color matrices based on UniqueCameraModel tag, while still taking advantage of any per-individual camera calibration performed by the camera manufacturer.
