A DSLR, or “Digital Single Lens Reflex” camera, uses a mirror mechanism to direct light from the lens to an optical viewfinder, allowing the photographer to see exactly what the lens sees. When the shutter is activated, the mirror moves aside, allowing light to reach the image sensor, capturing the photograph. While single-lens reflex cameras have been around in various forms since the 19th century, initially relying on film, the first commercially available digital SLR with an image sensor emerged in 1991. Unlike point-and-shoot or phone cameras, DSLR cameras allow for interchangeable lenses, offering greater flexibility. Working Principles of DSLR Camera When using a DSLR camera, the image seen through the viewfinder at the back of the camera is the actual view through the lens. This ensures you are previewing the precise scene you intend to capture. Light from the scene enters through the lens and hits a reflex mirror positioned at a 45-degree angle inside the camera. This mirror directs the light vertically to an optical component known as a “pentaprism.” The pent prism then reorients the light horizontally by passing it through two internal mirrors, delivering the final image into the viewfinder.
