ABSTRACT:
Systems, methods, and computer program products that identify and allow manipulation of shadows in a still frame (photo mode), or series of frames (movie mode). Manipulation of shadows includes such things as adjustment of shadow boundaries, softening of shadow boundaries, adjustment of shadow properties, and even removal of shadows altogether.
