The Lens Correction filter fixes common camera lens flaws, such as barrel
and pincushion distortion, in which straight lines bow out towards the
edges of the image (barrel) or bend inward (pincushion); chromatic aber-
ration, where a color fringe appears along the edges of image objects; and
vignetting at the edges of an image, especially corners, that are darker
than the center. Defects can occur from incorrectly setting the lens's focal
length or f-stop, or by tilting the camera vertically or horizontally.
