What does SLR mean in photography? It stands for Single Lens Reflex It is a type of camera that uses 1 lens. A long time ago they used cameras with 2 lenses, 1 to see thru and 1 to take the picture with, but noâ¦w they use cameras with 1 lens to do both.
Single Lense Reflex, meaning there is a single lens through which the light from the image you are going to capture enters the camera. When setting up the shot, and viewing it with a standard (35mm) SLR camera, the light is reflected by a mirror to the objective lens, where you view what the camera sees. D-SLR camera (Digital-SLR) generally lacks a realtime LCD preview, since the mirror is in the way, although newer DSLR cameras do offer the ability to offer the traditional preview like a standard digital.
