NAME
Image::ExifTool::CanonCustom - Read and Write Canon custom functions

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

DESCRIPTION
The Canon custom functions meta information is very specific to the camera model, and is found in both the EXIF maker notes and in the Canon RAW files. This module contains the definitions necessary for Image::ExifTool to read this information.
