What is a DSLR Camera?

Digital photography is now more accessible than ever before, thanks to cameras that can autofocus and store thousands of photographs on their internal memory cards – ideal for both professionals and amateur photographers. However, knowing your camera options before making a major investment is essential. A digital single-lens reflex camera (notable for permitting interchangeable lenses on the same camera body) is one form of digital camera.

How it works.

When light reaches the camera lens of a digital SLR camera, it is reflected by a mirror inside the camera body, allowing the photographer to see their subject via the optical viewfinder. The mirror swings out of the way when the shot is taken, allowing light to pass through to the digital image sensor, which records the image on an SD card. In contrast to mirrorless cameras, where light is sent directly to the image sensor and the photographer sees what they're shooting through a back-LCD screen or an electronic viewfinder, the photographer sees what they're shooting through a rear LCD screen or an electronic viewfinder.
