Definition
Light fall-off in the corner of images due to lens characteristics. There are mainly two types of vignetting. One caused by the lens housing sometimes called artificial vignetting and one caused by optical reasons (cosine-in-4th-power law) sometimes called natural vignetting. Only the last one can be easily corrected by panotools radial luminance filter.
