Camera Fields

These 117 columns in [AUROS].[DZFILESYSFILES].[FILETYPE DNG] preserve camera, device, lens, source, software, capture, location, and format-specific metadata embedded in DNG files. Values are copied from the file; they are not inferred.

DNG metadata: DNG is a TIFF/EXIF camera-RAW format and can carry direct camera identity, lens, sensor, calibration, source, software, capture, GPS, and original-RAW provenance metadata. A NULL value means the source file did not contain a readable value for that field.
