3D 입체영화 촬영공간(空間) 활용에 관한 연구

Abstract

The present 3D movie production industry in Korea barely has how to produce 3D images with ever-developing digital technology (from the stances of both the filmmakers and the audience), therefore it should be studied in divers methodological perspectives. This paper aims to provide the filmmakers with the technical understanding of 3D movie making and, as a result, help the audience to enjoy the comfortable 3D images. This research excludes the 3D cinematography, but includes the following: the interrelationship between the spatial establishment for 3D shooting and the audience's cognitive perception, and the parallax variables among the elements of the spatial art in movie production. The primary spatial perception of 3D images results from both the principle of human visual perception and the continuous training of the brain. The human visual cognitive perception in this process creates binocular vision, which often results in headache and vertigo. This paper shows the filmmakers how to minimize such symptoms by suggesting what kind of devices are required, how to choose right space and compose the devices in it, and how to use space, color and light effectively. The 3D movie shooting is not as simple as just dragging actors and other subjects into a rectangular frame . The 3D filmmakers must understand in full both 3D stereoscopic movie and its technological specifics in cinematography. The spatial establishment and composition of 3D cinema should also be based on 3D cinematography. Those who have done a 3D images project attest that they went through many tests and learned quite many aspects by trial and error. Though the 3D images usually are thought to be shot in the same process of 2D movie filming, the actual audience's perception of the 3D images is quite different from that of 2D images. Let's say you shot the same subjects in both 2D and 3D under the same environment. A certain visual detail in 2D images may not be detected in 3D images. And, some detail in 2D images is perceived in a totally different way in 3D images. More studies of the cognitive principles and the audience's perception should follow this paper.
