Although matte white materials such as CineWhite UHD-B are ideal for environments where room lighting can be controlled, the image is easily washed out by ambient light. Ambient Light Rejecting (ALR) materials such as the CineGrey 3D  are suitable for environments where there are high levels of indirect (ambient) light. This material trades off on the wide diffusion uniformity of white materials in favor of a brighter (angular reflective) image. AKIA’s CineGrey 3D incorporates a diffusion layer over a highly reflective surface which scatters ambient light while improving picture performance with a brighter image. This includes color neutrality with enhanced black levels and improvement over Active 3D presentations.
