The second type of slow motion is achieved during post production. This is known as time-stretching or digital slow motion. This type of slow motion is achieved by inserting new frames in between frames that have actually been photographed. The effect is similar to overcranking as the actual motion occurs over a longer time.
A normal motion picture film is played back at 24 frames per second, while television uses 25 frames/s or 29.97 frames/s . High-speed film cameras can film up to a quarter of a million fps by running the film over a rotating prism or mirror instead of using a shutter , thus reducing the need for stopping and starting the film behind a shutter ...
Muybridge's photographic sequence of a race horse galloping, first published in 1878. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...
PBS's NOVA series aired a full episode on time-lapse (and slow motion) photography and systems in 1981 titled Moving Still. Highlights of Oxford's work are slow-motion shots of a dog shaking water off himself, with close ups of drops knocking a bee off a flower, as well as a time-lapse sequence of the decay of a dead mouse.
Universal capture, a machine vision guided system, was the first ever motion picture deployment of an array of high definition cameras focused on a common human subject (actor, Neo) in order to create a volumetric photography. Like the concept of bullet time, the subject could be viewed from any angle yet, at the same time, the depth based ...
Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements. Long-exposure photography captures one element that conventional photography does not: an extended period of time.
This one-hour Abraham Lincoln documentary used period photographs, illustrations, artwork, newspapers and documents "animated" by the camera on an elaborate flatbed motion picture apparatus, and the descriptive term "stills in motion" for the technique was used in NBC's publicity and in the trade by the early 1960s.

Each camera was capable of recording only one exposure on a single sheet of film. Therefore, in order to create slow motion images, banks of four to ten cameras were set up to take photos in rapid succession. The average exposure time used was three microseconds.
