A digital single-lens reflex camera is a digital camera that uses a hardware mirror system and penta-prism in order to direct light from the lens to an optical viewfinder within the back of the camera.
The basic operation of a DSLR is as follows: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at a 90 degree angle. It is then reflected 3 times by the roof penta-prism, rectifying it for your photographer's eye. During exposure, the mirror assembly shifts upward, the aperture narrows, and a shutter unwraps allowing the lens in order to project light onto the image sensor. A second shutter next covers the sensor, ending the exposure, and the mirror lowers while shutter resets. The period that the actual mirror is flipped up is referred to as "viewfinder blackout ". A fast-acting mirror and also shutter is preferred so as to not delay an action photo.
All of this happens automatically more than a period of milliseconds, with cameras designed to do this 3-10 times per second. DSLRs are often preferred by professional still photographers because they allow an accurate preview of framing near to the moment of exposure, and because DSLRs allow the user available a variety of interchangeable lenses. Most DSLRs also have a function that allows accurate preview of level of field. Moreover, the cameras also offer a facility where you get to insert external lenses. This can either be the Nikon Wide Angle Lens or the Nikon Telephoto Lens, leased at an affordable camera lens rental.
Many professionals also prefer DSLRs for their larger sensors when compared to most compact digitals. DSLRs have sensors which usually are closer in size on the traditional film formats that many current professionals started out using. These large sensors allow for similar depths of subject and picture angle to film formats, as well as their particular comparatively high signal to help noise ratio.
The term DSLR generally refers to cameras that resemble 35 mm format cameras, although some medium format cameras are technically DSLRs.
