Photographs taken at high ISO sensitivities can be processed to
reduce “noise.”
“Vignetting” is a drop in brightness at the edges of a
photograph. Vignette control reduces vignetting for type G, E,
and D lenses (PC lenses excluded). Its effects vary from lens to
lens and are most noticeable at maximum aperture. Choose
from High, Normal, Low, and Off.

A Vignette Control
Depending on the scene, shooting conditions, and type of lens, JPEG
images may exhibit noise (fog) or variations in peripheral brightness,
while custom Picture Controls and preset Picture Controls that have
been modified from default settings may not produce the desired
effect. Take test shots and view the results in the monitor. Vignette
control does not apply to movies (
0 174) or to pictures taken with
lenses that support FX format.
