For example, a 28 mm lens on the DSLR (given a crop factor of 1.5) would produce the angle of view of a 42 mm lens on a full-frame camera. So, to determine the focal length of a lens for a digital camera that will give the equivalent angle of view as one on a full-frame camera, the full-frame lens focal length must be divided by the crop factor.
While there is no formal division between "wide-angle" and "panoramic" photography, "wide-angle" normally refers to a type of lens, but using this lens type does not necessarily make an image a panorama. An image made with an ultra wide-angle fisheye lens covering the normal film frame of 1:1.33 is not automatically considered to be a panorama.
Cross-section of a typical retrofocus wide-angle lens. Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film ...
For example, if standing at a distance so that a normal lens captures someone's face, a shot with a wide-angle lens or telephoto lens from the same distance will have exactly the same linear perspective geometry on the face, though the wide-angle lens may fit the entire body into the shot, while the telephoto lens captures only the nose.
Freelensing is a photography technique used with interchangeable lens cameras in both film-based and digital photography. The lens is detached from the camera and held in front of the lens mount by hand during exposure. This allows the lens to be tilted or shifted creating a similar effect to a perspective control or "Tilt-Shift" lens, only ...
The first music video to be shot completely with fisheye lens was for the Beastie Boys song "Hold It Now, Hit It" in 1987. In Computer Graphics, circular fisheye images can be used to create environment maps from the physical world. One complete 180-degree wide angle fisheye image will fit to half of cubic mapping space using the proper algorithm.
An extreme wide shot in the trailer to the 1963 film Cleopatra gives an expansive view of the set.. In photography, filmmaking and video production, a wide shot (sometimes referred to as a full shot or long shot) is a shot that typically shows the entire object or human figure and is usually intended to place it in some relation to its surroundings.

The focal length of a lens, together with the size of the image sensor or film in the camera, determines the angle of view. A lens is considered to be a "normal lens" in terms of its angle of view on a camera when its focal length is approximately equal to the diagonal dimension of the film format or image sensor format.
