=head1 NAME

Image::ExifTool::Shortcuts - ExifTool shortcut tags

=head1 SYNOPSIS

This module is required by Image::ExifTool.

=head1 DESCRIPTION

This module contains definitions for tag name shortcuts used by
Image::ExifTool.  You can customize this file to add your own shortcuts.

Individual users may also add their own shortcuts to the .ExifTool_config
file in their home directory (or the directory specified by the
EXIFTOOL_HOME environment variable).  The shortcuts are defined in a hash
called %Image::ExifTool::UserDefined::Shortcuts.  The keys of the hash are
the shortcut names, and the elements are either tag names or references to
lists of tag names.

An example shortcut definition in .ExifTool_config:

    %Image::ExifTool::UserDefined::Shortcuts = (
        MyShortcut => ['createdate','exif:exposuretime','aperture'],
        MyAlias => 'FocalLengthIn35mmFormat',
    );

In this example, MyShortcut is a shortcut for the CreateDate,
EXIF:ExposureTime and Aperture tags, and MyAlias is a shortcut for
FocalLengthIn35mmFormat.
