| vignetting |
A fall-off in brightness at the edges of an image, slide, or print. Can be caused by poor lens design, using a lens hood not matched to the lens, or attaching too many filters to the front of the lens.

A gradual reduction in density of parts of a photographic image due to the stopping of some of the rays entering the lens. A lens mounting may interfere with the extreme oblique rays. An antivignetting filter is one that gradually decreases in density from the center toward the edges; it is used with many wide-angle-lenses to produce a photograph of uniform density by cutting down the overexposure of the center of the photograph.

| vignetting |
Restriction of an FOV such that all parts of a desired imaging surface at the focal plane (such as a CCD chip, a piece of film, or the eye's pupil) are not illuminated by the entire primary optical element. Usually caused by an undersized or improperly placed secondary, or by narrow apertures in the focuser/camera assembly.
