NAME

Image::ExifTool::TagNames - ExifTool tag name documentation

DESCRIPTION

This document contains a complete list of ExifTool tag names, organized into tables based on information type. Tag names are used to indicate the specific meta information that is extracted or written in an image.

TAG TABLES

The tables listed below give the names of all tags recognized by ExifTool, excluding shortcut and unknown tags.

A Tag ID or Index is given in the first column of each table. A Tag ID is the computer-readable equivalent of a tag name, and is the identifier that is actually stored in the file. An Index refers to the location of the information, and is used if the information is stored at a fixed position in a data block.

A Tag Name is the handle by which the information is accessed. In some instances, more than one name may correspond to a single tag ID. In these cases, the actual name used depends on the context in which the information is found. Case is not significant for tag names. A question mark after a tag name indicates that the information is either not understood, not verified, or not very useful -- these tags are not extracted by ExifTool unless the Unknown (-u) option is enabled.

The Writable column indicates whether the tag is writable by ExifTool. Anything but an "N" in this column means the tag is writable. A "Y" indicates writable information that is either unformatted or written using the existing format. Other expressions give details about the information format, and vary depending on the general type of information. The format name may be followed by a number in square brackets to indicate the number of values written, or the number of characters in a fixed-length string (including a null terminator which is added if required).

An asterisk (*) in the Writable column indicates a 'protected' tag which is not writable directly, but is set via a Composite tag. A tilde (~) indicates a tag this is only writable when print conversion is disabled (by setting PrintConv to 0, or using the -n option). An exclamation point (!) indicates a tag that is considered unsafe to write under normal circumstances. These 'unsafe' tags are not set when calling SetNewValuesFromFile() or when using the exiftool -TagsFromFile option, and care should be taken when editing them manually since they may affect the way an image is rendered.

The HTML version of these tables also list possible Values for all tags which have a discrete set of values, and give Notes for some tags.

Note: If you are familiar with common meta-information tag names, you may find that some ExifTool tag names are different than expected. The usual reason for this is to make the tag names more consistent across different types of meta information. To determine a tag name, either consult this documentation or run exiftool -S on a file containing the information in question.

EXIF Tags

EXIF meta information may exist within different Image File Directories (IFD's) of 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.

XMP Tags

All XMP information is stored as character strings. An integer in this format is a string of digits, possibly beginning with a '+' or '-', and a rational is composed of two integer strings separated by a '/' character. A date is a date and/or time string in the format 'YYYY:MM:DD HH:MM:SS[+/-HH:MM]'. A boolean is either 'True' or 'False', and lang-alt is a list of string alternatives in different languages. Currently, ExifTool only writes the 'x-default' language in lang-alt lists.

The Group column below gives the XMP schema namespace prefix for each tag. The family 1 group names are composed from these schema names with a leading "XMP-" added. If the same XMP tag name exists in more than one group, all groups are written unless a family 1 group name is specified. ie) If XMP:Contrast is specified, information will be written to both XMP-crs:Contrast and XMP-exif:Contrast.

Note: that the actual IPTC Core namespace schema prefix is Iptc4xmpCore, which is the name used in the file, but ExifTool uses iptcCore to generate the family 1 group name because Iptc4xmpCore is a bit lengthy.

IPTC Tags

The IPTC specification dictates a length for ASCII (string or digits) values. These lengths are given in square brackets after the Writable format name. For tags where a range of lengths is allowed, the minimum and maximum lengths are separated by a comma within the brackets. IPTC strings are not null terminated.

IPTC information is separated into different records, each of which has its own set of tags.

GPS Tags

ExifTool is very flexible about the input format for lat/long coordinates, and will accept 3 floating point numbers (for degrees, minutes and seconds) separated by just about anything. Many other GPS tags have values which are fixed-length strings. For these, the indicated string lengths include a null terminator which is added automatically by ExifTool.

Nikon LensData Tags

Nikon encrypts the LensData information below if LensDataVersion is 0201, but the decryption algorithm is known so the information can be extracted. It isn't yet writable, however, because the encryption adds complications which make writing more difficult.

CanonRaw Tags

Photoshop Tags

Many Photoshop tags are marked as Unknown (indicated by a question mark after the tag name) because the information they provide is not very useful under normal circumstances. Unknown tags are not extracted unless the Unknown (-u) option is used.
