Abstract: The present invention comprises a system for and method of frequency prefiltering comprising a camera shutter capable of continuously variable illumination during a single exposure of the sensor. The shutter comprises a continuously variable exposure effector which in disposed in an image path, either in front of a lens or between a lens and a sensor. The system for frequency prefiltering further comprises a synchronization cable that synchronizes a drive system with a sensor or with film. The shutter further comprises a postfilter. The postfilter comprises a digital finite impulse response convolutional filter.
