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, JP2, PGF, MIFF, HDP, PSP and XCF images, as well as

many TIFF-based RAW images, and even some AVI and MOV videos.

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.

The table below lists all EXIF tags. Also listed are TIFF, DNG, HDP and other tags which are not part of the EXIF

specification, but may co-exist with EXIF tags in some images. Tags which are part of the EXIF 2.3 specification

have an underlined Tag Name in the HTML version of this documentation. See

/english/hyoujunka/kikaku/pdf/DC-008-2010_ for the official EXIF 2.3 specification.
