This stereoscopic viewing method is identical to the process in Anaglyph 3D movies. He also sold amateur film cameras and projectors and produced 3-D anaglyph image slides. Anaglyph 3D images contain two differently filtered colored images, one for each eye. Anaglyph and polarized glasses are distributed to audiences at 3D movies. Process reconfigures the typical anaglyph image to have less parallax. The 3-D comic books were one of the most interesting applications of anaglyph to printing. The polarization system has better color fidelity and less ghosting than the anaglyph system. Video games, theatrical films, and DVDs can be shown in the anaglyph 3D process. It contains an anaglyph 3D feature as well as HDR lighting. This film was released on DVD in the Anaglyph 3D process. Disney Studios released "" in August 2008, its first anaglyph 3D Blu-ray Disc.
