Peripheral Illumination Correction, Distortion Correction, and
Chromatic Aberration Correction
To perform peripheral illumination correction, distortion correction, and
chromatic aberration correction, the correction data of the lens used is
necessary. If you cannot apply correction when processing RAW images in
the camera, use EOS Utility (EOS software, p.512) to register the correction
data to the camera.
 Processing RAW images in the camera will not produce exactly the
same results as processing RAW images with Digital Photo Professional.
 When processing images with [Distortion correction] set to [Enable],
AF point display information (p.352) or Dust Delete Data (p.405) will not
be appended to the image.
