EXIF Tags

EXIF stands for "Exchangeable Image File Format". This type of information is formatted according to the TIFF specification, and may be found in JPG, TIFF, PNG, MIFF and WDP images, as well as many TIFF-based RAW images.

The EXIF meta information is organized into different Image File Directories (IFD's) within an image. The names of these IFD's correspond to the ExifTool family 1 group names. When writing EXIF information, the default Group listed below is used unless another group is specified.

Also listed in the table below are TIFF, DNG, WDP and other tags which are not part of the EXIF specification, but may co-exist with EXIF tags in some images.
