## NAME
    [Image::ExifTool::CanonRaw](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3ACanonRaw/markdown) - Read Canon RAW (CRW) meta information

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

## DESCRIPTION
    This module contains definitions required by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown) to interpret meta information from
    Canon CRW raw files. These files are written directly by some Canon cameras, and contain meta
    information similar to that found in the EXIF Canon maker notes.

## NOTES
    The CR2 format written by some Canon cameras is very different the CRW format processed by this
    module. (CR2 is TIFF-based and uses standard EXIF tags.)
