1. History of 3D Film. 2. Bwana Devil Known as the first feature-length3D film. Released in 1952. It had the slogan A lion in your lap! A lover in your arms! The movie earned $2.7 millionin rentals in North America in 1953. The film was a critical failure, but a runaway success with audiences. The audience wore 3-D glasseswith grey Polaroid filters. 3. Bwana Devil You can see from the picture onthe right that it was a massive thing to go see a 3D film, people are dressed in suits and dresses, now everyone goes to the cinema dressed casually. Bwana Devils Natural Vision sparked interest in other directors such as Alfred Hitchcock who created his own 3D Film Dial M For Murder in 1954. More 3D films were made during this boom period. For the most part, studios seemed to gravitate towards horror movies when it came to 3D. 4. Decline in popularity Despite these advances, 3Dmovies fell out of popularity by the middle of the decade. The reasons for the decline were mostly technical. 3D projectors required two reels to be displayed in perfect synchronization. Small errors in synchronization could easily lead to eye strain and headaches among viewers. Keeping reels in good repair was also an ongoing concern. 5. New ideas 3D's second renaissance came A company called Stereovisionsome time later when producer Arch Gobler found a way to eliminate the need for dual-reel movies.developed another new technology in 1970. Stereovision's 3D format displayed reels side-by-side on a single, anamorphic film strip. His new technique, Space-Vision 3D, worked by overlaying two stereoscopic images on a single reel. As long as reels were spliced properly during printing, viewers no longer needed to worry about syncing issues. Many of these films in the '70sand '80s were marketed squarely at older viewers and fans of violent horror films. 6. Criticisms Late film critic Late filmcritic Roger Ebert repeatedly criticized 3D film as being "too dim", sometimes distracting or even nausea-inducing, and argued that it is an expensive technology that adds nothing of value to the movie-going experience (since 2-D movies already provide a sufficient illusion of 3D). A Film critic argued that3D adds "not that much" value to a film, and said that, while he liked Avatar, the many impressive things he saw in the movie had nothing to do with 3D.
