If a group name is not specified when writing information, then the information is added only to the highest priority group for which the tag name is valid (however, the information is updated in all groups where the tag already existed).The priority of the groups is given by the list above.
it is the mother of all EXIF utilities; the BFG of meta-data extraction; the Pan Galactic Gargle Blaster of EXIF tools ...This thing will suck the last bit of metadata out of whatever image file you throw at it!(But note that the characters Hint: Options may also be added to the "Target" property of a Windows shortcut for the executable.Using a shortcut has 3 advantages over adding options in the file name: 1) different shortcuts may be created without requiring multiple copies of the executable, 2) characters which are invalid in file names may be used, and 3) the shortcuts can be given more meaningful (and convenient) file names.Specifically, this means that new information is added preferentially to the EXIF group, or to the IPTC group if no corresponding EXIF tag exists, or finally to the XMP group.
Alternatively, information may be written to a specific group only, bypassing these priorities, by providing a group name for the tag.Exif Tool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, Geo TIFF, ICC Profile, Photoshop IRB, Flash Pix, AFCP and ID3, as well as the maker notes of many digital cameras by Canon, Casio, DJI, FLIR, Fuji Film, GE, Go Pro, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Motorola, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony.Exif Tool is also available as a stand-alone Windows executable and a Mac OS package: (Note that these versions contain the executable only, and do not include the HTML documentation or other files of the full distribution above.) "...Be sure to keep a copy of the original, or thoroughly validate the new file before erasing the original.(Read here for some ramblings on the subject of writing meta information.) Tag values are written rather than being extracted if any tag name ends with a ' option, but for a single tag.ii) Stand-alone version in the Windows GUI: Double-click on "" to read the application documentation, or drag-and-drop files and folders to run exiftool on the selected files.
