DSLR stands for “Digital Single Lens Reflex”. In simple language, a
DSLR is a digital camera that uses a mirror mechanism to either
reflect 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 are taking a picture of) or let light fully pass onto the
image sensor (which captures the image) by moving the mirror out
of the way. Although single lens reflex cameras have been available
in various shapes and forms since the 19th century with film as the
recording medium, the first commercial digital SLR with an image
sensor appeared in 1991. Compared to point-and-shoot and phone
cameras, DSLR cameras typically use interchangeable lenses.!
