The term originally referred to the main, full-length film in early cinema programs that also included one or more short films, newsreels, or advertisements presented before the main event. In modern usage the term more commonly indicates simply that a film is of a substantial length or running time, as distinguished from short films, though ...
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
Rangefinder Camera Mechanism. Some cameras do not have a beam splitter; these cameras instead have a separate viewfinder.The first rangefinders, sometimes called "telemeters", appeared in the twentieth century; the first rangefinder camera to be marketed was the 3A Kodak Autographic Special of 1916; the rangefinder was coupled.
The default orientation for most half frame cameras is vertical (portrait) as opposed to the horizontal (landscape) orientation of a full frame 35 mm SLR or rangefinder. The exceptions are cameras that use vertically run film mechanisms (examples including the Konica Recorder and Belomo Agat 18).
A size of film or image sensor somewhat larger than the 35mm film standard of 36 × 24 mm. MILC: Mirrorless interchangeable-lens camera. Similar to a digital single-lens reflex camera, but having an electronic or rangefinder type of viewfinder in place of the mirror and pentaprism, to allow a more compact design. See also EVIL camera.
Eyepiece image of a naval rangefinder, showing the displaced image when not yet adjusted for range. The coincidence rangefinder uses a single eyepiece. Light from the target enters the rangefinder through two windows located at either end of the instrument. At either side the incident beam is reflected to the center of the optical bar by a ...
The most common sheet film size for press cameras was the 4×5 inch film format. [ 1 ] [ 2 ] Models have also been produced for the 2.25×3.25 inch format (6×9 cm), 3.25×4.25 inch format and various 120 film formats [ 3 ] from 6×6 cm. through 6×12 cm. European press cameras, such as the Goerz and Van Neck , used the 9×12cm format ...
A stereoscopic rangefinder or stereoscopic telemeter [1] is an optical device that measures distance from the observer to a target, using the observer's capability of binocular vision. It looks similar to a coincidence rangefinder, which uses different principles and has only one eyepiece. German instruments tended to use the stereoscopic ...
