Edison applied for the motion picture camera patent on July 31, 1891 and three years later the movie industry was born with the opening of the first Kinetoscope parlor in New York City. The basis of Edison’s patent is that the rays of reflected light can be captured through a single lens and projected on a series of two dimensional planes of light sensitive media framed over time.
The optical system Edison used, the one we have been accustomed to since this beginning of the motion picture industry has thus been based on a single point of view of the light rays reflected off an object. And while we have added a second capturing system to effectively produce a three dimensional image in our minds, the second image captured is still only a two dimensional capture of a single point of light rays. Is this optical system we have become accustomed to over the past century, the only system?
In 1846 Michael Faraday, known more for the his work with magnetic fields and electricity, did a lecture suggesting that light flows in every direction and thus should be viewed as a field as opposed to rays. In 1936, Alexander Gershun wrote in a paper on the radiometric properties of light in three-dimensional space, coined the phrase “Light Field” to what Faraday had suggested.
This month Jon Karafin, Head of Light Field Video at Lytro, will discuss the practical applications of Light Field cinematography and its future in filmmaking.
About Lytro: At NAB 2016 Lytro introduced the world's first Light Field solution for cinema and broadcast. Lytro Cinema is a breakthrough capture system that enables the complete virtualization of the live action camera -- transforming creative camera controls from fixed on set decisions to computational post-production processes -- and allows for what has been historically impossible shots.
