Slow Motion is a filming technique and or Computer Simulation method whereby the action/time appear to move slower. The slow motion technique using a mirrored drum as a synchronizing mechanism was invented by August Musger. The device he used was patented in 1904 and was first presented in Graz, Styria in 1907 using a projector made by K. Löffler, owner of a cinema. Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. The technical term for slow motion is overcranking which refers to the concept of cranking a handcranked camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay, than to film. High-speed photography is a more sophisticated technique that uses specialized equipment to record fast phenomena, usually for scientific applications, e.g slow motion film of water droplets
