R Processing RAW Images with the CameraN
Chromatic aberration correction
When [Enable] is set, lateral chromatic aberration caused by the
lens (color fringing along the subject’s outline) can be corrected. If
[Enable] is set, the corrected image will be displayed. (The image
periphery will also be slightly cropped.) If the effect is difficult to
discern, press the <u> button to magnify the image. (Press the
<I> button to return to the normal view.) The chromatic
aberration correction done with the camera will be less pronounced
than with Digital Photo Professional (provided software). Therefore
the correction might not be so noticeable. In such a case, use Digital
Photo Professional to correct the chromatic aberration.
About peripheral illumination correction, distortion
correction, and chromatic aberration correction
To execute peripheral illumination correction, distortion correction, and
chromatic aberration correction with the camera, the data of the lens used
for the shot must be registered in the camera. If the lens data has not been
registered in the camera, use EOS Utility (provided software, p.282) to
register the lens data.
Distortion correction and chromatic aberration correction are not possible
for RAW images shot with an Extender attached.
Processing RAW images in the camera will not produce the same results
as processing RAW images with Digital Photo Professional.
Even if image verification data (p.232) is appended to the RAW image,
the image verification data is not appended to the JPEG image after
processing.
