As explained in the previous chapter, to create a stereoscopic movie, two cameras are required to capture the film simultaneously with each mimics the human eye. We can achieve this effect by having two cameras film side-by-side. The only dis-advantage of using this method is that we cannot cramped the interaxial distance by placing the camera extremely close side-by-side as most professional films cameras are huge and bulky. The only kind of shoots that are feasible by placing the camera close to each other is for the purpose of taking a medium to long shots.

To film a close up shot, a type of custom camera rig is used to narrow the interaxial distance. This rig is called mirror rig or beam splitter. One camera is placed hori-zontally while the other camera is placed vertically. A semi-transparent mirror is placed at a 45 degrees’ angle which reflects the vertical camera while allowing the horizontal camera to shoot straight through shown in Figure 4.The interaxial distance can be …show more content…
Some companies would rather film the entire movie in 2D and later convert it to 3D to avoid the challenging production pipeline which involves more money and more time to make (11). Filming in native 3D with stereoscopic camera is much more complex and more expensive and requires more workload than custom-ary method. However, the conversion has become more common since there is an increase of films in 3D. Back in 2006, the director of the movie Superman Returns: An IMAX 3D experience, Bryan Singer spent $10 million dollars to convert one important scene in 3D however it was unfortunately cut during the theatrical release and hope that it can reappear in the future (12). The cost of a scene was great 10 years ago in comparison to current times. Now, there are computer programs and software that are able to convert 2D images to
