Single-Lens Reflex (SLR)

Technology / Digital Cameras / Single-Lens Reflex (SLR): An SLR, or single-lens reflex, camera is named for its picture-taking mechanism. In a film SLR, the viewfinder uses a 45°-angled mirror to see through the lens; that mirror snaps out of sight quickly when you press the shutter button, to let light enter and expose the film. A digital SLR works the same way, except that the shutter is opening to let an electronic sensor record the image. SLRs are revered by serious photographers because they permit the use of many different specialized lenses and flashes, and provide faster response time and higher continuous shooting speed than most point-and-shoot cameras.
