# File: example.config --> ~/.ExifTool_config
#
# Description: Sample user configuration file for Image::ExifTool
#
# Notes: This example file shows how to define your own shortcuts and
# add new EXIF, IPTC, XMP, PNG, MIE and Composite tags, as well
# as how to specify preferred lenses for the LensID tag, and
# define new file types and default ExifTool option values.
#
# Note that unknown tags may be extracted even if they aren't
# defined, but tags must be defined to be written. Also note
# that it is possible to override an existing tag definition
# with a user-defined tag.
#
# To activate this file, rename it to ".ExifTool_config" and
# place it in your home directory or the exiftool application
# directory. (On Mac and some Windows systems this must be done
# via the command line since the GUI's may not allow filenames to
# begin with a dot. Use the "rename" command in Windows or "mv"
# on the Mac.) This causes ExifTool to automatically load the
# file when run. Your home directory is determined by the first
# defined of the following environment variables:
#
# 1. EXIFTOOL_HOME
# 2. HOME
# 3. HOMEDRIVE + HOMEPATH
# 4. (the current directory)
#
# Alternatively, the -config option of the exiftool application
# may be used to load a specific configuration file (note that
# this must be the first option on the command line):
#
# exiftool -config example.config ...
#
# This example file defines the following 16 new tags as well as
# a number of Shortcut and Composite tags:
#
# 1. EXIF:NewEXIFTag
# 2. GPS:GPSPitch
# 3. GPS:GPSRoll
# 4. IPTC:NewIPTCTag
# 5. XMP-xmp:NewXMPxmpTag
# 6. XMP-exif:GPSPitch
# 7. XMP-exif:GPSRoll
# 8. XMP-xxx:NewXMPxxxTag1
# 9. XMP-xxx:NewXMPxxxTag2
# 10. XMP-xxx:NewXMPxxxTag3
# 11. XMP-xxx:NewXMPxxxStruct
# 12. PNG:NewPngTag1
# 13. PNG:NewPngTag2
# 14. PNG:NewPngTag3
# 15. MIE-Meta:NewMieTag1
# 16. MIE-Test:NewMieTag2
#
# For detailed information on the definition of tag tables and
# tag information hashes, see lib/Image/ExifTool/README.
