    Shutter Efficiency and Temporal Sampling



    It is commonly acknowledged that the instantaneous shutter model used in primitive rendering systems produces images which are unrealistic and animate poorly. However the introduction of motion blur as implemented in most modern renderers uses a shut- ter model which is equally implausible. One of the few articles to examine this effect is [Glassner 1999], which considers the behavior of focal plane shutters. While the results obtained from the simulation of focal plane shutters are dramatic, more subtle and useful images can be obtained by considering the case of a leaf shutter, which is embedded within the lens elements.
