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 ...
The shutter behavior of the camera influences aliasing, as the overall shape of the exposure over time determines the band-limiting of the system before sampling, an important factor in aliasing. A temporal anti-aliasing filter can be applied to a camera to achieve better band-limiting and reduce the wagon-wheel effect. [2]
Some sound effects were synchronized by electro-magnetic devices, triggered by metal parts on the strip, while a score with some songs was performed live. From 28 October 1892 to March 1900, Reynaud gave over 12,800 shows to a total of over 500,000 visitors at the Musée Grévin in Paris.
The first known movie made as a test of the Kinetophone was shot at Edison's New Jersey studio in late 1894 or early 1895; now referred to as the Dickson Experimental Sound Film, it is the only surviving movie with live-recorded sound made for the Kinetophone. In March 1895, Edison offered the device for sale; involving no technological ...
Revolog is a small company based in Vienna, Austria which re-manufactures and sells a range of creative 'special effects' still camera films. Revolog take standard ISO 200 color film in 135 format and pre-expose the rolls with a special effect. [190] In 2019 they also re-manufacture creative films for dubblefilm. [36]
In film, smaller MOS cameras, lacking sound circuitry, may be used for greater portability and ease of setup. [3] In electronic news-gathering (ENG) and documentary film projects, B-roll footage is often shot after the main interview is shot, to provide supporting scenes for what was said by the interview subject.

Lower-cost cameras and low-light or low-contrast situations will make the effect more pronounced and it is in these cases that AF lag is more noticed. Most AF systems use contrast to determine focus; in situations where contrast is low, the speed at which the camera can determine the best focus can be quite noticeable. Since most modern cameras ...
An in-camera effect is any visual effect in a film or video that is created solely by using techniques in and on the camera and/or its parts. The in-camera effect is defined by the fact that the effect exists on the original camera negative or video recording before it is sent to a lab or modified.
