Digital Single-lens Reflex Camera
Digital single-lens reflex cameras (also named digital SLR or DSLR) are digital cameras combining the parts of a single-lens reflex camera (SLR) and a digital camera back, replacing the photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design scheme, light travels through a single lens and a mirror is used to reflect a portion of that light through the view finder - hence the name Single Lens Reflex. The image that is seen through the view finder is also the image that is captured by the camera's sensor.

Famous quotes containing the words reflex and/or camera:
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
“If I were just curious, it would be very hard to say to someone, “I want to come to your house and have you talk to me and tell me the story of your life.” I mean people are going to say, “You’re crazy.” Plus they’re going to keep mighty guarded. But the camera is a kind of license. A lot of people, they want to be paid that much attention and that’s a reasonable kind of attention to be paid.”
—Diane Arbus (1923–1971)
