The CineGrey 3D®/CineGrey 5D® are angular reflective front projection materials that reflect at the mirror-opposite angle. If an ultra-short throw projector is used, the material will reflect the steep narrow light and reflect it upwards instead of to the viewer’s eye level. As you can see from the picture, the image looks foggy and unwatchable due to the projector’s light being reflected in the wrong direction. The material is reflecting and absorbing and treating it as ambient light.
The image appears to look good, but is still reflecting the projector light upwards and causing a hotspot in the middle of the image. Overhead lights are being absorbed/reflected off the material while providing great color saturation, image brightness, and black levels for a contrast rich presentation.
