Digital SLR Camera Basics

V

viewfinder

A window in which the photographer frames the subject and checks focus.

vignetting

Loss of illumination at the periphery of an image. The degree of loss depends on the subject and shooting conditions: in some cases, it may be more pronounced in some corners of the image than in others. Vignetting may be caused by a lens or lens hood blocking light from the flash and casting shadows on the subject.

VR lens

A lens incorporating Nikon's unique vibration reduction technology. Two sensors in the lens sense pitching (front-back rotation) and yawing (left-right rotation) motions and adjust an internal set of lens elements to minimize blur.
