Abstract
A method is described for producing and projecting a theater quality entertainment motion picture, by photographing and then projecting the motion picture on a screen, which creates an unusually vivid impression of realism. The film frames have a resolution of over 40 line pairs per milimeter, and each frame has an area of at least 0.36 square inch, which creates more than 10 million pixels per frame on the film and on the screen. The illumination level on the screen is at least 15 foot lamberts. The film frames are photographed and projected at a predetermined constant rate of more than 50 frames per second, such as 60 fps. The high resolution and light level, combined with the unusually high frame rate, has been found to produce an unusually vivid impression of realism.
