Rolling shutter describes the process of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, vertically, horizontally or rotationally. Thus, not all parts of ...
Full frame, where the image sensor is approximately the same size as a 35 mm film: 36 × 24 mm. FP: Focal plane. A shutter that opens and closes near to the film or image sensor, usually as a fast-moving slit, as contrasted with a bladed/leaf shutter located near a nodal point of a lens. [12] FPA: Focal plane array. A matrix of sensors ...
An electronic shutter can compensate for the exposure change caused by a speed ramp without changing the aperture and affecting depth of field. Other types of shutter adjustments, such as an out-of-phase shutter and a fluttering shutter, are also possible. Normally the film is held steady in the gate whenever it is exposed to light.
Mechanical shutter can accommodate up to 1/16000 seconds (for example the Minolta Dynax/Maxxum/α-9 film camera had a maximum of 1/12000, a record in its era, and the later digital Nikon D1 series were capable of 1/16000), while electronic shutter can accommodate at least 1/32000 seconds, used for many superzoom cameras and currently many ...
Focal-plane shutter top speed peaked at 1/16,000 s (and 1/500 s X-sync) in 1999 with the Nikon D1 digital SLR. The D1 used electronic assist from its sensor for the 1/16,000 s speed and its 15.6×23.7 mm "APS-size" sensor was smaller than 35 mm film and therefore easier to cross quickly for 1/500 s X-sync.

High-speed film cameras can film up to a quarter of a million fps by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for stopping and starting the film behind a shutter which would tear the film stock at such speeds. Using this technique one second of action can be stretched to more than ten ...
Normal lens - a lens with a focal length about equal to the diagonal size of the film or sensor format, or that reproduces perspective that generally looks "normal" to a human observer. Cross-section of a typical short-focus wide-angle lens. Wide angle lens - a lens that reproduces perspective that generally looks "wider" than a normal lens ...
The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a ...
