What is a DSLR (Digital SLR) Camera?
“Digital Single Lens Reflex” is the abbreviation for “Digital Single Lens Reflex.” In layman’s terms, a DSLR is a digital camera that uses a mirror mechanism to either redirect light from a camera lens to an optical viewfinder (which is an eyepiece on the back of the camera that one looks through to see what they’re photographing) or to allow light to completely move onto the image sensor (which captures the image) by shifting the mirror out of the way. While single lens reflex cameras with film as the recording medium have been available in various shapes and forms since the 19th century, the first commercial digital SLR with an image sensor appeared in 1991.DSLR cameras, unlike point-and-shoot and phone cameras, usually use interchangeable lenses.

2) How DSLR Cameras Work:
When you look through the back of a DSLR camera’s viewfinder / eyepiece, everything you see is passed through the lens attached to the camera, which means you might be looking at just what you’re going to film. Light from the scene you’re trying to photograph passes through the lens and through a reflex mirror (#2) inside the camera chamber, which then forwards the light vertically to an optical element known as a “pentaprism” (#7). The pentaprism then transforms the vertical light to horizontal light by focusing it through two separate mirrors directly into the viewfinder (#8).
