Even in dark situations where fast shutter speeds cannot be used because of low ISO sensitivity, increasing the sensitivity allows use of fast shutter speeds to provide correct exposure, resulting in minimal image blur caused by camera shake. If the scene is extremely dark, so that image blur cannot be successfully corrected by increasing ISO sensitivity, Nikon's VR (Vibration Reduction) will effectively do the job. VR is also effective when high ISO sensitivity is not desired.
