RG Specs

Star ratings one to five for “modern” (1990′s+) 3D movies.

Until 2008 or so, 3D movies could only be seen in Theme Parks or IMAX.

Now digital theaters offer several options: RealD, Dolby (Infitec) or XpanD (among others)

Another consideration is whether a film has been converted from 2D. Live action is much more difficult to shoot in 3D than it is to render CG (computer graphics) into stereo. Therefore, conversion is an expensive ($100,000 per minute) and time consuming process and while it offers flexibility, it’s rarely as strong as “real” stereo. We consider conversion to 3D a lot worse than converting black and white to color! Of course, some may not even notice the difference!
