Peripheral light fall-off is a phenomenon that makes the image corners 
look darker due to the lens characteri stics. Color fringing along subject 
outlines is called chromatic aberra tion. Both lens aberrations can be 
corrected. RAW images can be corrected with Digital Photo 
Professional (provided software, p.366).
