Folding Camera
A folding camera is a camera type. Folding cameras fold into a compact and rugged package for storage. The lens and shutter are attached to a lens-board which is connected to the body of the camera by a light-tight folding bellows. When the camera is fully unfolded it provides the correct focus distance from the film. The key advantage of folding cameras is their excellent physical-size to film-size ratio when the camera is folded for storage. Portable folding cameras dominated camera design from the 1890s to 1930s and were significant into the late 1940s. Specialized cameras such as the Polaroid SX-70 Instant film camera, and the Speed Graphic press cameras used folding designs into the 1970s. The typical amateur camera of the early 20th Century made various "postcard" sized negatives around 4" × 5". By the 1930s 6 cm × 9 cm cameras for either the 120 or 620 film size, were highly popular. The use of folding cameras declined in the late 1930s with advances in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amateur
An amateur () is generally considered a person who pursues an avocation independent from their source of income. Amateurs and their pursuits are also described as popular, informal, autodidacticism, self-taught, user-generated, do it yourself, DIY, and hobbyist. History Historically, the amateur was considered to be the ideal balance between pure intent, open mind, and the interest or passion for a subject. That ideology spanned many different fields of interest. It may have its roots in the ancient Greek philosophy of Amateur sports, amateur athletes competing in the Olympic Games, Olympics. The ancient Greek citizens spent most of their time in other pursuits, but competed according to their natural talents and abilities.

Single Lens Reflex
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Polaroid Corporation
Polaroid is an American company best known for its instant film and cameras. The company was founded in 1937 by Edwin H. Land, to exploit the use of its Polaroid polarizing polymer. Land ran the company until 1981. Its peak employment was 21,000 in 1978, and its peak revenue was $3 billion in 1991. When the original Polaroid Corporation was declared bankrupt in 2001, its brand and assets were sold off. The "new" Polaroid formed as a result, itself declared bankruptcy in 2008, resulting in a further sale to Polish billionaire Wiaczesław Smołokowski. In May 2017, the brand and intellectual property of Polaroid Corporation were acquired by the largest shareholder of the Impossible Project, which had originally started out in 2008 by producing new instant films for Polaroid cameras. The Impossible Project was renamed Polaroid Originals in September 2017, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USSR
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev ( Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR).

Kodak Retina
Retina was the brand-name of a long-running series of German-built Kodak 35mm cameras, produced from 1934 until 1969. Kodak Retina cameras were manufactured in Stuttgart-Wangen by the Kodak AG Dr. Nagel Werk which Kodak had acquired in December 1931. The Retina line included a variety of folding and non-folding models, including the Retina Reflex single lens reflex camera. Retina cameras were noted for their compact size, high quality, and low cost compared to competitors. These cameras retain a strong following today, of both photographers and collectors. Kodak AG also offered a companion line of less-expensive Retinette cameras, with similar looks and function. History August Nagel was a prolific camera designer and entrepreneur who was one of the founders of Zeiss Ikon, when he merged his company, Contessa-Nettel AG, with Zeiss and others to form that group in 1919. As well as being an owner he was an active designer of fine Zeiss cameras including miniatures. He lef ... [...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 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speed Graphic
The Speed Graphic was a press camera produced by Graflex in Rochester, Monroe County, New York, Rochester, New York. Although the first Speed Graphic cameras were produced in 1912, production of later versions continued until 1973; with the most significant improvements occurring in 1947 with the introduction of the Pacemaker Speed Graphic (and Pacemaker Crown Graphic, which was lighter and lacked the focal plane shutter). Description Despite the common appellation of ''Speed Graphic'', various Graphic models were produced between 1912 and 1973. The authentic Speed Graphic has a focal plane shutter that the Crown Graphic and Century Graphic models lack. The eponymous name "speed" came from the maximum speed of 1/1000 sec. that could be achieved with the focal plane shutter. The Speed Graphic was available in 2¼ x 3¼ inch, 3¼ x 4¼ inch, 5 x 7 inch and the most common format 4 x 5 inch. Because of the focal plane shutter, the Speed Graphic can also use lenses that do not have s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instant Film
Instant film is a type of photographic film that was introduced by Polaroid Corporation to produce a visible image within minutes or seconds of the photograph's exposure. The film contains the chemicals needed for developing and fixing the photograph, and the camera exposes and initiates the developing process after a photo has been taken. In earlier Polaroid instant cameras the film is pulled through rollers, breaking open a pod containing a reagent that is spread between the exposed negative and receiving positive sheet. This film sandwich develops for some time after which the positive sheet is peeled away from the negative to reveal the developed photo. In 1972, Polaroid introduced ''integral film'', which incorporated timing and receiving layers to automatically develop and fix the photo without any intervention from the photographer. Instant film has been available in sizes from (similar to 135 film) up to size, with the most popular film sizes for consumer snapshots be ...
