Tripods are used for both still and motion photography to prevent camera movement. They are necessary when slow-speed exposures are being made, or when zoom lenses are used.
Any camera movement while the shutter is open will produce a blurred image.
A tripod is also helpful in achieving precise framing of the image, or when more than one image is being made of the same scene, for example when bracketing the exposure
Use of a tripod may also allow for a more thoughtful approach to photography. For all of these reasons a tripod of some sort is often necessary for professional photography as well as certain video uses. Tripods are also used to support small to medium-sized telescopes, large firearms, handheld optics (like binoculars), spotting scopes, and similar applications.
It's designed for DSLRs.
