1950s 3D

3D movies are becoming increasingly popular as film-makers try to use this feature as a way to distinguish their offerings from high definition home theaters. There was another 3D film boom in the 1950s, with films such as "House of Wax" and "Creature From the Black Lagoon" filling cinemas. Almost all of these films used polarized projection, even though everyone today seems to think colored glasses were used by filmgoers. 1950s 3D movies were presented with dual synchronized projectors. Misalignment and splices would create headache inducing image problems, one of the reasons 3D films faded from popularity. This isn't an issue with current digital 3D projection technologies.
