A Spatial Post-Processing Algorithm for Images of Night Scenes
William B. Thompson, Peter Shirley, James A. Ferwerda · Journal of Graphics Tools · 2002
The standard technique for making images viewed at daytime lighting levels look like images of night scenes is to use a low overall contrast, low overall brightnesses, desaturation, and to give the image a “blue shift.” This paper introduces two other important effects associated with viewing real night scenes: visible noise, and the loss of acuity with little corresponding perceived blur.
