What format are 3D movies in?

3D movies are typically presented in formats that enhance depth perception, using techniques like stereoscopic imaging. This involves displaying two slightly different images—one for each eye—to create the illusion of three-dimensional depth. Common formats for 3D movies include RealD 3D, IMAX 3D, and Dolby 3D, which utilize polarized or active shutter technology for viewing. Additionally, some films may be converted from 2D to 3D in post-production for theatrical release.
