Digital cinematography captures motion pictures digitally in a process analogous to digital photography.While there is a clear technical distinction that separates the images captured in digital cinematography from video, the term "digital cinematography" is usually applied only in cases where digital acquisition is substituted for film acquisition, such as when shooting a feature film.
The film's finale was created with mechanically controlled slit-scan photography, which required precise camera motion control during the exposure of single frames. The first large-scale application of motion control was in Star Wars (1977), where a digitally controlled camera known as the Dykstraflex performed complex and repeatable motions ...
Star Wars: Episode I – The Phantom Menace (1999) was the first feature-length film to include a main character created using motion capture (that character being Jar Jar Binks, played by Ahmed Best), and Indian-American film Sinbad: Beyond the Veil of Mists (2000) was the first feature-length film made primarily with motion capture, although ...
A computer file format for coloured images, restricted to 256 colours and useful for small file-size. [8] GN: Guide number. A value indicating the power of an electronic flash apparatus, and used to estimate exposure. GN = distance × f-number. One needs to specify the film or sensor ISO speed, and it is conventional to quote for ISO 100/21°.
That distance is sometimes given on the filter in millimeters. A +3 close-up lens has a maximal working distance of 0.333 m or 333 mm. The magnification is the focal distance of the objective lens (f) divided by the focal distance of the close-up lens; i.e., the focal distance of the objective lens (in meters) multiplied by the diopter value (D) of the close-up lens:
