Lens Peripheral Illumination / Chromatic Aberration Correction

Peripheral light fall-off is a phenomenon that makes the image corners
look darker due to the lens characteristics. Color fringing along subject
outlines is called chromatic aberration. Both lens aberrations can be
corrected. The default settings are [Enable] for both corrections.
