=head1 NAME

Image::ExifTool::NikonCustom - Read and Write Nikon custom settings

=head1 SYNOPSIS

This module is loaded automatically by Image::ExifTool when required.

=head1 DESCRIPTION

The Nikon custom functions are very specific to the camera model (and
sometimes even change with firmware version).  The information is stored as
unformatted binary data in the ShotInfo record of the Nikon MakerNotes.
This module contains the definitions necessary for Image::ExifTool to decode
this information.

=head1 ACKNOWLEDGEMENTS

Thanks to Jens Duttke and Warren Hatch for their help decoding the D300, D3
and Z9 custom settings.  And thanks to the customer service personnel at
Best Buy for not bugging me while I spent lots of time playing with their
cameras.
