3D Glasses used In DVD & Blu-Ray home release of theatrical 3D films. Disney studios is releasing its first Blu-ray 3D disk August 2008, Hannah Montana & Miley Cyrus: Best of Both Worlds Concert. Disney Channel aired it originally in July of 2008, for viewing with red-cyan paper 3D glasses. In all probability it will use similar 3D glasses in the blu-ray release. The greater clarity of blu-ray, and the learning curve at Disney, has greatly improved red-cyan anaglyph 3D Glasses, especially in relation to close overlay of the 3D images, such as they have followed in their animation projects. When put up against the older techniques of polarization or anaglyphs, most 3D images in theatres showing Disney films display much reduced mal-registration. What makes 3D Anaglyph Glasses function? Anaglyphs are seen as a different picture by each eye when viewed through properly colored 3D glasses. An example is the red-blue anaglyph 3D glasses, the red filtered lens makes the red parts of the image appear as "white", while the blue parts are seen as "black". (with the brain providing some adaption for color); the eye covered by the blue filter perceives the opposite effect. Each eye perceives true black or true white areas the same way. 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. 3D Glasses from Rainbow Symphony Inc.
