Distortion Correction - Canon EOS 60D Instruction Manual

Color space (p.110)
You can select either sRGB or Adobe RGB. Since the camera's LCD
monitor is not compatible with Adobe RGB, the image will not look
very different when either color space is set.
Peripheral illumination correction (p.102)
You can set [Enable] or [Disable]. If [Enable] is set, the corrected
image will be displayed. If the effect is difficult to discern, press the
<u> button to magnify the image and look at the image corners.
(Press the <I> button to return to the normal view.)

Distortion correction

When [Enable] is set, image distortion caused by the lens is
corrected. If [Enable] is set, the distortion-corrected image will be
displayed. The correction will have the image periphery to be
cropped. Therefore, the image will look slightly larger (It is not a
magnified image). With Digital Photo Professional (provided
software), you can correct the image distortion while minimizing the
trimming of the image periphery.
Since the image resolution may look slightly lower, use the Picture
Style's Sharpness setting to make adjustments as necessary.
