## NAME
    [Image::ExifTool::Shortcuts](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AShortcuts/markdown) - ExifTool shortcut tags

## SYNOPSIS
    This module is required by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown).

## DESCRIPTION
    This module contains definitions for tag name shortcuts used by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown). 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](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AUserDefined%3A%3AShortcuts/markdown). 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](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AUserDefined%3A%3AShortcuts/markdown) = (
            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.

    The target tag names may contain an optional group name prefix. A group name applied to the
    shortcut will be ignored for any target tag with a group name prefix.
