Class Information
Number: 352
Name: Optics: motion pictures >
Description: This class includes structure motion picture cameras, which record motion picture cameras, upon a single actuation a series of individual photographs which are separated in time. Generally the recording rate is related to the persistence of vision when the photograph series is used to accurately portray an action. However, special types of cameras are included which record the picture series at rates differing greatly from the normal persistence of vision time so as to produce a series of pictures of utility other than the creation of a motion illusion or to create a motion illusion with the rate of motion greatly exaggerated.
