Afterimages are a common physiological phenomenon, typically caused by staring at bright light, such as the headlights of a car at night. This continuous trail of varying multicolored responses remains registered by the visual system, eventually fading out. Research on afterimages has been done for centuries, but real progress has been slow. Digital afterimage synthesis has been recently introduced to computer graphics. One of the few existing methods attempts to simulate the color and luminance transitions of afterimages using data from psychophysical and physiological experiments. Although this yields plausible results, the method is limited to still photographs. We extend this technique to the production of afterimages for moving, high-intensity light sources. This extension widens the range of applications that can benefit from the creative use of digital afterimages and should stimulate further research on the topic.
