Folding camera

The introduction of films enabled the existing designs for plate cameras to be made much smaller and for the base-plate to be hinged so that it could be folded up compressing the bellows. These designs were very compact and small models were dubbed vest pocket cameras. Folding rollfilm cameras were preceded by folding plate cameras, more compact than other designs. A folding camera is a camera that can be folded to a compact and rugged package when not in use. The camera objective is sometimes attached to a pantograph-like mechanism, in which the lid usually is a component. The objective extends to give correct focus when unfolded. A cloth or leather bellows keeps the light out. When folded, the camera has an excellent physical size to film size ratio. This feature was very appealing when the only film formats available were large or medium format films. Folding cameras were dominant from the beginning of the 20th century to WWII, and medium format folders were produced in USSR until the 1960s[citation needed]. The typical amateur camera of the 1930s was a folding 6 x 9 camera using either the 120 or 620 film size. The use of folding cameras began to decline after WWII with the development of the 35mm film format, which allowed the construction of small-sized cameras without use of a bellows. However, some 35 mm cameras were also of the folding type, such as the original Kodak Retina. Polaroid Corporation produced a number of instant film folding cameras, including the famous SX-70, which was also a single lens reflex camera. The Seagull Camera model 203 was, t roughout the 1970s, 1980s and 1990s an inexpensive folding camera often used as an introductory medium format camera. In 2008, Voigtlander announced the Bessa III in its Classic Collection of retro-style camera bodies, a new 6x6 / 6x7 (120/220 film) medium format folding camera. Retina was the name of a long-running series of German-built Kodak 35mm cameras. Retinas were manufactured in Stuttgart by Nagel Kamerawerk, which Kodak had acquired in 1931, and sold under the Kodak nameplate. Retinas were noted for their compact size, quality, and low cost compared to their competitors and retain a strong following today. The original Retina, was introduced in 1934. The Retina line continued until 1969 with a variety of folding and nonfolding models, including the Retina Reflex SLR. Kodak also sold a companion line of less-expensive Retinette cameras.Polaroid Corporation is an American-based international consumer electronics and eyewear company, originally founded in 1937 by Edwin H. Land. It is most famous for its instant film cameras, which reached the market in 1948, and continued to be the company's flagship product line until the February 2008 decision to cease all production in favor of digital photography products.[1] The company's original dominant market was in polarized sunglasses, an outgrowth of Land's self-guided research in polarization after leaving Harvard University after his freshman yearhe later returned to Harvard to continue his research. After Polaroid defeated Kodak in a patent battle, Kodak left the instant camera business on January 9, 1986.
