A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
Film stock made of nitrate, acetate, or polyester bases is the traditional medium for capturing the numerous frames of a motion picture, widely used until the emergence of digital film in the late 20th century. film theory film transition film treatment filmmaking. Sometimes used interchangeably with film production.
Rangefinder Camera Mechanism. Some cameras (Argus C3, etc) do not have a beam splitter; these cameras instead have a seperate 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.
Until the development of SLR, all cameras with viewfinders had two optical light paths: one through the lens to the film, and another positioned above (TLR or twin-lens reflex) or to the side (rangefinder). Because the viewfinder and the film lens cannot share the same optical path, the viewing lens is aimed to intersect with the film lens at a ...
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.
A stereoscopic rangefinder uses two eyepieces and relies on the operator's visual cortex to merge the two images into a single picture. A reference mark is separately inserted into each eyepiece. The operator first adjusts the direction of the range finder so that the fixed mark is centered on the target, and then the prisms are rotated until ...
If the scene is illuminated with a sheet of light this creates a reflected line as seen from the light source. From any point out of the plane of the sheet the line will typically appear as a curve, the exact shape of which depends both on the distance between the observer and the light source, and the distance between the light source and the reflected points.
In 1997, the Voigtländer brand was licensed to Cosina, which subsequently introduced an unrelated line of 135 film rangefinder cameras using the Bessa name. However, Cosina also manufactured and sold a folding rangefinder medium format camera as the Bessa III (aka Bessa 667 ; rebadged and also sold as the Fujifilm GF670) from 2008 to 2014.
