The History of Stereoscopy in Cinema - Text 6
It was not until December 2009, however, with Avatar, that exhibitors rushed to install digital projectors. This enabled them to show this film in 3D and attract more customers. The digital projector and improvements to the movie screen made possible high-quality 3D screenings, if the movie theatre kept a proper eye on the projection. James Cameron and Vince Pace had developed a digital 3D camera, the Fusion Camera System, equipped with two lenses in order to shoot in 3D directly without the need to convert 2D into 3D in post-production.[5] This sort of conversion is often criticized, because the stereograph, which regulates the 3D camera on the set, cannot act on it in the same way. Recreating 3D in post-production gives more freedom to producers, who “diminish” the 3D effects for fear of viewer complaints.[6] In theory, if one is closer to the movie theatre screen the 3D effect is less pronounced, while the effects are clearer at the back of the hall (depth, and the coming out of the screen effect).
