A lens with an Angle of View narrower than that of the human eye and a normal lens. (Normal, Long, and Wide Angle are relative terms and depend on film or Aperture size.) 50mm is wide for a 4 x 5 view camera, normal for a 35mm still camera, and long for a video camera. Telephotos are long lenses in the optical sense, but are by design shorter in the physical sense. See: Perspective.tiffaneduglossary
A lens of relatively long focal length with a narrower angle of view than a normal lens, but with a more enlarged view of the scene.
A telephoto lens.
Involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements. The paths of moving light sources become clearly visible. For best results, practice in low-light conditions or with a very slow film speed.
- Any lens with a focal length greater than normal; a normal focal length approximates the size relationships seen by the human eye, while a long focal length creates a narrower angle of vision, causing a larger image. A long lens alters perspective by flattening a subject into its background. (See telephoto.)
A lens with a focal length greater than 25mm in 16mm, or 50mm in 35mm, which, like binoculars, will provide a view that magnifies a small area.
