A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

The reflex design scheme is the primary difference between a DSLR and other digital cameras.

In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor.

The alternative would be to have a viewfinder with its own lens, hence the term "single lens" for this design.

By using only one lens, the viewfinder of a DSLR presents an image that will not perceptibly differ from what is captured by the camera's sensor.

A digital camera or digicam is a camera that produces digital images that can be stored in a computer, displayed on a screen and printed.

Most cameras sold today are digital, and digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles.

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.

A simple lens consists of a single piece of transparent material, while a consists of several simple lenses (elements), usually arranged along a common axis.

Lenses are made from materials such as glass or plastic, and are ground and polished or moulded to a desired shape.

A lens can focus light to form an image, unlike a prism, which refracts light without focusing.

Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses.

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
