3D Pictures With Anaglyph 3D Glasses
Films released as 3D in theaters will also provide a 3D experience on DVD and Blu-Ray with 3D glasses. The first Blu-ray 3D disk will be the Hannah Montana & Miley Cyrus: Best of Both Worlds Concert released by Disney studios in August 2008. Disney Channel aired it originally in July of 2008, for viewing with red-cyan paper 3D glasses.

Very likely, it will employ similar 3D glasses for the Blu-Ray release. Thanks to Disney’s research, and the greater clarity of blue-ray, there have been great improvements in red-cyan anaglyph 3D glasses, particularly as they relate to the close overlay of 3D images, like Disney uses in their animation products. When put up against the older techniques of polarization or anaglyphs, most 3D images in theatres showing Disney films display much reduced mal-registration.

How do 3D Anaglyph Glasses Work?

3D glasses with the correct coloring cause anaglyphs to display a slightly altered image to each eye. For example, in a red-blue anaglyph 3D glasses, the eye that is covered by the red filter will see red parts of an image as white whereas it will see the blue parts as black. (with the brain providing some adaption for color); the eye that is covered by the blue filter will perceive exactly the opposite effect. The perception of regions of true white or true black is identical for each eye. In the brain, the images from the two eyes are blended together and the differences are interpreted as being a change of distances. This creates a normal stereograph image without requiring the viewer to cross his or her eyes.
