DSLR stands for digital single-lens reflex camera. On most digital SLRs the capture device is smaller in size than a 35 mm negative and the field of view provided by a lens is effectively cropped. DSLR Cameras are increasingly becoming a type of camera that is in the reach of the average photographer as prices fall and as manufacturers develop more user friendly models.

DSLR is Digital Single lens reflex. It uses an automatic mirror system and pentaprism or pentamirror to direct light from the lens through the viewfinder eyepiece.

The basic operation of a DSLR is as follows: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at an approximately 90 degree angle. It is then reflected by the pentaprism to the photographer's eye. During exposure (when the photograph is taken), the mirror swings upward, and a shutter opens, allowing the lens to project light onto the image sensor.
