Roll Film
Roll film or rollfilm is any type of spool-wound photographic film protected from white light exposure by a paper backing. The term originated in contrast to sheet film. Confusingly, roll film was originally often referred to as "cartridge" film because of its resemblance to a shotgun cartridge. The opaque backing paper allows roll film to be loaded in daylight. It is typically printed with frame number markings which can be viewed through a small red window at the rear of the camera. A spool of roll film is usually loaded on one side of the camera and pulled across to an identical take up spool on the other side of the shutter as exposures are made. When the roll is fully exposed, the take up spool is removed for processing and the empty spool on which the film was originally wound is moved to the other side, becoming the take up spool for the next roll of film. History In 1881 a farmer in Cambria, Wisconsin, Peter Houston, invented the first roll film camera. His younger br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
120 Film
120 is a film format for still photography introduced by Kodak for their '' Brownie No. 2'' in 1901. It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film survives to this day as the only medium format film that is readily available to both professionals and amateur enthusiasts. Characteristics The 120 film format is a roll film which is nominally between 60.7 mm and 61.7 mm wide. Most modern films made today are roughly 61 mm (2.4 inches) wide. The film is held in an open spool originally made of wood with metal flanges, later with all-metal, and finally with all-plastic. The length of the film is nominally between and , according to the ISO 732:2000 standard. However, some films may be as short as . The film is attached to a piece of backing paper longer and slightly wider than the film. The backing paper protects the film while it is wound on the spool, with enough extra length to allow loading and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snapshot (photography)
A snapshot is a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent and usually made with a relatively cheap and compact camera. Common snapshot subjects include the events of everyday life, often portraying family members, friends, pets, children playing, birthday parties and other celebrations, sunsets, tourist attractions and the like. Snapshots can be technically "imperfect" or amateurish: poorly framed or composed, out of focus, and/or inappropriately lighted by flash. Automated settings in consumer cameras have helped to obtain a technologically balanced quality in snapshots. Use of such settings can reveal the lack of expert choices that would entail more control of the focus point and shallower depth of field to achieve more pleasing images by making the subject stand out against a blurred background. Snapshot photography can be considered the purest form of photography in providing images with the characteristics th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hasselblad H2F
Victor Hasselblad AB is a Swedish manufacturer of medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. In 2016, Hasselblad introduced the world's first digital compact mirrorless medium-format camera, the X1D-50c, changing the portability of medium-format photography. Hasselblad produces about 10,000 cameras a year from a small three-storey building. Company history The company was established in 1841 in Gothenburg, Sweden, by Fritz Wiktor Hasselblad, as a trading company, F. W. Hasselblad and Co. The founder's son, Arvid Viktor Hasselblad, was interested in photography and started the pho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fujifilm GX680IIIS Professional
The Fuji GX680 is a series of single lens reflex system cameras for medium format film produced by Fujifilm with interchangeable camera lenses and interchangeable film holders for the unusual film format 6×8 cm on 120 and 220 roll film. The distinguishing feature of the Fuji GX680 is the articulating front standard, which runs on a rail connecting lens and camera body by a bellows; the interchangeable lens is permanently mounted to a lens board. In contrast to competing medium-format cameras, e.g. Mamiya RB67 and RZ67 and Rolleiflex SL66, for some models of the Fuji GX680 the front standard can be shifted right, left, up and down for perspective control, and the front standard can also be tilted on horizontal and vertical axes to control depth of field using the Scheimpflug principle. Therefore, the Fuji GX680 has many of the same camera movements of a large format view camera, only limited by restricted motions of the front standard and a fixed rear standard, makin ...

Medium Format
Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the used in 35 mm photography (though not including 127 sizes), but smaller than (which is considered large format photography). In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range. Characteristics Medium-format cameras made since the 1950s are generally less automated than smaller cameras made at the same time. For example, autofocus became available in consumer 35 mm cameras in 1977, but did not reach medium format until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems Hi ...

Barcode
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called ''matrix codes'' or ''2D barcodes'', although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode reader using special ...

Barcode System
DX (Digital indeX) encoding is an ANSI and I3A standard, originally introduced by Kodak in March 1983, for marking 135 and APS photographic film and film cartridges. It consists of several parts, a latent image DX film edge barcode on the film below the sprocket holes, a code on the cartridge used by automatic cameras, and a barcode on the cartridge read by photo-finishing machines. History In order to simplify the handling of 35 mm film in 135 format Kodak introduced the DX encoding method on 3 January 1983. In contrast to former solutions like Fuji's film speed encoding method in 1977, which was already using electrical contacts for film speed detection on 135 format cartridges, Kodak's later DX code system immediately met success in the marketplace. The first DX encoded film was the color negative film Kodacolor VR-1000 in March 1983. The first cameras to use the technology was the Konica TC-X SLR (1985), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
