A projector is an apparatus for presenting an enlarged image on a screen from a transparency such as a photographic slide or a film. In a motion picture projector, each frame is held stationary at an illuminated aperture for a brief period, and then advanced by an intermittent sprocket or reciprocating claw, the light being cut off by a rotating shutter during the movement. One should have a clear idea about video projectors before buying video projector screens.Video projectors have become common and captured the market throughout the world. They are especially common in schools and colleges where it becomes necessary to show videos and films (especially in film schools and institutes), or any place where people need to show films on a regular basis at a cheap rate to a large number of people.There is a wide range of video projector screens available in the market. One can buy the kind of video projector screen one wants depending on the kind of surface. The surfaces vary from smooth to rough, and minutely undulated ones. However, before considering any video projector screens, one should consider the following elements: resolution, brightness or reflectivity, contrast, color accuracy, and build quality.Some of the white (or gray) video projection screens can bring about a difference in resolution, or image detail. There should be a rating to indicate its inherent reflectivity, on which the brightness of the image depends. Contrast of the image is also dependent to great extent on the video projection screen. A screen should not reflect any color other than that of the projector itself.Article Source: http://EzineArticles.com/?expert=Jennifer_Bailey
