⁴¹So called Bullet Time is a variable speed method of photography used in recent films, broadcast advertisements and computer games which is characterized both by its extreme permutation of time (slow enough to show normally imperceptible and un-filmable events, such as flying bullets) and space (by way of the ability of the camera angle to move around the scene at a normal speed while events are slowed). It is usually a computer generated effect which was popularized in the movie “The Matrix” (1999).
