# Image::ExifTool::CanonCustom - phpMan

## 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.
