SLR stands for "Single Lens Reflex" and is a term commonly used in photography. It refers to a type of camera that utilizes a mirror and prism system to allow the user to see through the same lens that captures the image. This configuration distinguishes SLR cameras from other camera types like rangefinder or point-and-shoot cameras.
The main feature of an SLR camera is its reflex mirror, which sits at a 45-degree angle inside the camera body, reflecting the light coming through the lens onto a focusing screen. When the shutter button is pressed, this mirror briefly moves out of the way, allowing the light to reach the image sensor or film to capture the image. The mirror then quickly returns to its original position, which allows the photographer to see the actual focus and framing of the image through the viewfinder.
Another crucial component in an SLR camera is the prism, which reflects the light from the focusing screen to the viewfinder, providing an accurate representation of what the final image will look like. This feature allows photographers to preview and compose their shots precisely.
SLR cameras are highly versatile and widely used by both professionals and enthusiasts due to their interchangeable lens systems, manual controls, and excellent image quality. They offer a range of creative possibilities, allowing photographers to control settings such as aperture, shutter speed, and ISO to achieve the desired results.
