ChromaDepth 3D is a patented system from American Paper Optics that produces a stereoscopic effect based upon differences in the diffraction of color through a special prism-like holographic film fitted into the glasses. ChromDepth 3D glasses purposely exacerbate chromatic aberration and give the illusion of colors taking up different positions in space, with red being in front, and blue being in back. This works particularly well with the sky, sea or grass as a background, and red objects in the foreground. With our ChromaDepth 3D glasses, any media piece can be given a 3D effect as long as the color spectrum is put into use with the foreground being in red, and the background dark. From front to back, the scheme follows the visible light spectrum, from red to orange, yellow, green and blue. As a result, ChromaDepth 3D works best with artificially produced or enhanced pictures, since the color indicates the depth. ChromaDepth 3D contains depth information in one image, which eliminates the ghosting seen in other schemes when one attempts to view them without 3D glasses. Thus, ChromaDepth images can be viewed comfortably and legibly without glasses, even though the 3D effect will not be perceivable without them.
