Inside a DNG file

  • SubIFDType 0 is the original raw data
  • SubIFDType 1 is the thumbnail data
  • The recommendation is to store the thumbnail as the first IFD
  • TIFF metdata goes in the first IFD
  • EXIF tags are preferred
  • Camera profiles are stored in the first IFD

Required tags

  • DNGVersion
  • UniqueCameraModel

Neat tags

  • AnalogBalance stores the gains applied to the RGB channels by the sensor
