O Some noise appeared in the periphery of an image after

correcting [Peripheral illumination]

You can reduce the noise by using luminance and/or chromatic noise

reduction of the noise reduction function (p.57). However, if you had

applied high amount of [Peripheral illumination] correction to the

images that have been shot at night or with a high ISO speed, the

noise might not be reduced.

O The image appears with less resolution after correcting

[Distortion]

You can make the image similar to the one before correction by

applying more sharpness with the sharpness adjusting function

(p.29).

O The colors of the image became weaker after correcting [Color

blur]

You can make the image similar to the one before correction by

adjusting the color tone (p.27) and/or the color saturation (p.89) to

make the color deeper.

O The result of [Color blur] correction cannot be detected

[Color blur] correction is effective for correcting blue or red color blur

which occurs at the edge of the highlighted area of an image. If

conditions do not match, correction cannot be made.

Additional information

The periphery of the image may be truncated when [Distortion]

correction is made.

For a list of the [Lens aberration correction] window functions, refer

to p.114.
