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 another chromatic aberration. Both lens aberrations can be
corrected. RAW images can be corrected with Digital Photo
Professional (provided software, p.350).
