Whois & Analysis for bestbuycapm.com

In photography, a tripod is used to stabilize and elevate a camera, a flash unit, or other photographic equipment.

All photographic tripods have three legs and a mounting head to couple with a camera.

The mounting head usually includes a thumbscrew that mates to a female threaded receptacle on the camera, as well as a mechanism to be able to rotate and tilt the camera when it is mounted on the tripod.

Tripod legs are usually made to telescope, in order to save space when not in use.

Tripods are usually made from aluminum, carbon fiber, steel, wood or plastic.

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.

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

The images may be individual still photographs or sequences of images constituting videos or movies.

The camera is a remote sensing device as it senses subjects without physical contact.

The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.

The modern photographic camera evolved from the camera obscura.

The functioning of the camera is very similar to the functioning of the human eye.

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.

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard.

UAVs are a component of an ; which include a UAV, a ground-based controller, and a system of communications between the two.

The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator, or fully or intermittently autonomously, by onboard computers.

More emerged during World War II – used both to train antiaircraft gunners and to fly attack missions.

Nazi Germany produced and used various UAV aircraft during the war.

Jet engines entered service after World War II in vehicles such as the Australian GAF Jindivik, and Teledyne Ryan Firebee I of 1951, while companies like Beechcraft offered their Model 1001 for the U.S. Navy in 1955.

Nevertheless, they were little more than remote-controlled airplanes until the Vietnam War.
