What Is A Single Lens Reflex (SLR) Camera?
A single lens reflex (SLR) camera is a type of camera that uses a mirror mechanism to reflect light from the lens into an optical viewfinder. This allows the photographer to see exactly what the lens sees when composing an image. The “single lens” aspect indicates that there is only one lens used for both viewing and taking the picture, while the “reflex” part refers to the mirror’s reflection of the image projected by the lens.
SLR cameras are popular among photographers due to their versatility and image quality. They are equipped with interchangeable lenses, allowing for a wide range of photography styles, from portrait to landscape. Additionally, the optical viewfinder offers a real-time view, which is advantageous for composing shots in varying lighting conditions.
How Does The Mirror Mechanism In An SLR Camera Work?
The mirror mechanism in an SLR camera plays a crucial role in capturing images. When you look through the viewfinder, the light that enters the lens is directed upwards by a mirror placed at a 45-degree angle. This mirror reflects the light into a prism or directly into the viewfinder, allowing you to see the scene through the lens. The mirror remains in this position while composing a shot.
When you press the shutter button, the mirror flips up, allowing the light to reach the image sensor (in digital SLRs) or film (in analog SLRs). This temporary movement creates a brief blackout in the viewfinder, as the light path is now unobstructed. Once the exposure is complete, the mirror returns to its original position, enabling you to resume framing your next shot.
