Anaglyph images are used to provide a stereoscopic 3D effect when viewed with 2 colour glasses, usually cyan and red. The images are made up of these two colour layers superimposed but offset to produce a depth effect. This allows the viewer to perceive features in three dimensions, as they were intended to be viewed when the imagery was originally taken.
