Description
Used in IFD 0 of DNG files.
A UTF-8 encoded string associated with the CameraCalibration1 and CameraCalibration2 tags. The CameraCalibration1 and CameraCalibration2 tags should only be used in the DNG color transform if the string stored in the CameraCalibrationSignature tag exactly matches the string stored in the ProfileCalibrationSignature tag for the selected camera profile.
Note that the DNG specification allows UTF-8 encoded strings for this tag. This is different from normal ASCII TIFF tags, in that it's not necessarily limited to ASCII. The Count should be the number of bytes in this string, including the null terminator byte, not the character count.
