3D cinemas

A 3D film or S3D (stereoscopic 3D) films are a motion picture that enhances the illusion of depth perception. It’s derived from stereoscopic photography. A regular motion picture camera system is used to record the images as seen from two perspective (or computer-generated imagery generates the two perspective in post-production) , and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3Dfilms are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, especially since 3D television and Blu-ray 3D.
3D films have existed in some form since 1915, but had been largely relegated to a niche in motion picture industry because of the costly hardware and process required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business. Nonetheless, 3D films were prominently featured in 1950s in American cinema, and later experienced a worldwide resurgence in 1980s and 1990s driven by IMAX high-end theaters and Disney themed-venues. 3D films became more and more successful throughout the 2000s, culminating in the unprecedented success of 3D presentation of avatar in December 2009 and January 2010.
