This is a measure of reflectivity of light compared to a screen coated with magnesium carbonate[5] titanium dioxide[6] or barium sulfate [7] when the measurement is taken for light targeted and reflected perpendicular to Outdoor projection screen screen.

Glass-bead screens exhibit a phenomenon of retroreflection ; the light is reflected more intensely back to its source than in any other direction. Popcorn machine available for hire on your event Outdoor projection screen. Electric screens can be wall mounted, ceiling mounted or ceiling recessed.

With retroreflective screens, the screen center might be brighter than the screen periphery, a kind of hot spotting. Titanium dioxide is a bright white colour, but greater gains can be accomplished with materials that reflect more of the light parallel Outdoor projection screen projection axis and less off-axis.

Because of the said effect, these screens are also less vulnerable to ambient light coming from the sides of the screen, as well. Selectively reflective screens[ edit ] Certain screens are claimed to selectively reflect the narrow wavelengths of projector light while absorbing other wavelengths in the optical spectrum.

Some light will always be created in the room when an image is projected, increasing the ambient light level and thus contributing to the degradation of picture quality. Screens with high gain also have a narrower usable viewing angleas the amount of reflected light rapidly decreases as the viewer moves away from front of such screen.

Curved screens can be made highly reflective without introducing any visible hot spots, if the curvature of the screen, placement of the projector and the seating arrangement are designed correctly. The potential improvement from a grey screen may thus be best realized in a darkened room, where the only light is that of the projector.

Unfortunately, at the perpendicular direction used for gain measurement, mirror reflection and retroreflection are indistinguishable, and this has sown confusion about the behavior of high gain screens.

No stakes or ground penetration. A grey screen may thus succeed almost as well in delivering a bright-looking image, or fail to do so in other circumstances. People may perceive a wide range of luminosities as "white", as long as the visual clues present in the environment suggest such an interpretation.

A second common confusion about screen gain arises for grey colored screens. Image brightness and contrast[ edit ] Apparent contrast in a projected image — the range of brightness — is dependent on the ambient light conditions, luminous power of the projector and the size of the image being projected.

A darker grey screen reflects less light, of course—both light from the projector and ambient light. This is possible because humans have greater sensitivity to contrast in smaller details, but less so in luminosity variations as great as half of the screen. Ambient light originating from other sources may reach the eye immediately after having reflected from the screen surface, giving no advantage over a white high-gain screen in terms of contrast ratio.
