TERMS AND DESCRIPTIONS
Anaglyph 3D
The name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. (Wikipedia) Anaglyph 3D is visually inferior to the newer Bluray 3D standard. Note that there are a few Bluray releases that use Anaglyph 3D but they are clearly noted in the title's index on this site.
