Hasselblad
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.

Victor Hasselblad
Victor Hasselblad (8 March 1906 – 5 August 1978) was a Swedish inventor and photographer, known for inventing the Hasselblad 6x6 cm medium format (film), medium format camera. Life and work Hasselblad was born in Gothenburg. In 1940 Swedish Air Force officers requested Hasselblad to construct a camera that rivaled the one found in a Luftwaffe, German reconnaissance aircraft shot down over Sweden. Hasselblad founded the Hasselblad, Victor Hasselblad AB company in 1941 to produce cameras for the Swedish Air Force. Hasselblad was famous for always trying out Hasselblad AB's new camera models by photographing birds. For example, Hasselblad 2000 was tried a week at Nidingen, the only place in Sweden where the black-legged kittiwake nests. By 1948, the company introduced the first civilian Hasselblad camera, the 1600F, in New York City. Over time, Hasselblad has become a standard camera for many professional photographers. On his death, Hasselblad willed Swedish krona, SEK 78 mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medium Format (film)
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 unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cameras
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeiss Biogon
Biogon is the brand name of Carl Zeiss for a series of photographic camera lenses, first introduced in 1934. Biogons are typically wide-angle lenses. History The first lens branded Biogon (2.8 / 3.5 cm, unbalanced) was designed in 1934 by Ludwig Bertele, then assigned to Zeiss Ikon Dresden, the Contax created as a modification of the then Sonnar. It was developed by Carl Zeiss in approximately 1937 and manufactured in Jena, then a redesign in Oberkochen. In 1951, a new Biogon with a 90° angle of view (Super Wide Angle) was designed, also by Ludwig Bertele. The advent of the Biogon opened the way to extreme wide-angle lenses. The first examples were produced from 1954 as the 4.5 / 21 mm for Contax, in 1954, 4.5 / 38 mm for Hasselblad Super Wide, and from 1955 to 1956 as the 4.5 / 53 mm and 4.5 / 75 mm for the Linhof. The original patent spanned three different variants, each with a different maximum aperture: 6.3, 4.5, and 3.4 lenses. Examples Since t ...

Sixten Sason
Sixten Sason (born Sixten Andersson; 1912–1967) was a Swedish industrial designer, noted for his work in designing several generations of Saab automobiles. Biographical Sason was born in 1912, the son of a Swedish sculptor. He trained in Paris as an artist and later as an industrial designer. He had a stint in the Swedish Air Force until an injury disqualified him for flight. In the 1930s he became noted for his "x-ray" renderings of industrial products. Career with Saab Sason started working for Saab, designing aircraft throughout World War II. In 1946, he was asked to contribute to Project 92, the result of which would be the first Saab automobile, the Saab 92 which began production in 1949. Sason remained with Saab, designing the 93, 95, 96, and 99, as well as the first Sonett. Following his death in 1967, Sason was succeeded by his colleague and one-time student, Björn Envall. Many of the design elements that Sason implemented in the 99 continued as elements of S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Bertele
Ludwig Jakob Bertele (25 December 1900 – 16 November 1985) was a German optics constructor. His developments received universal recognition and serve as a basis for considerable part of the optical designs used today. Biography Ludwig Jakob Bertele was born 25 December 1900 in Munich, to an architect's family. In 1916, Bertele was employed as the assistant of an optics designer at Rodenstock GmbH in Munich. In 1919, he moved to Dresden to work at under the supervision of August Klughardt, as a designer of optics. In the same year, Bertele would begin the development of a type of ptical scheme subsequently known as . Its basis was the optical scheme of the Ultrastigmat cinema lens, a modified Cooke triplet, which had been developed by Charles C. Minor in 1916 and produced by Gundlach Company. The main purpose of Bertele's developmental work was to increase the light-gathering power of a lens as well as diminishing optical aberration. In 1923, after four years of developme ...

Gothenburg
Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County. It is situated by the Kattegat, on the west coast of Sweden, and has a population of approximately 590,000 in the city proper and about 1.1 million inhabitants in the metropolitan area. Gothenburg was founded as a heavily fortified, primarily Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges (e.g. tax relaxation) given to his Dutch allies from the ongoing Thirty Years' War, the king also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries. Gothenburg is home to many students, as the city inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slide Projector
A slide projector is an opto-mechanical device for showing photographic slides. 35 mm slide projectors, direct descendants of the larger-format magic lantern, first came into widespread use during the 1950s as a form of occasional home entertainment; family members and friends would gather to view slide shows. Reversal film was much in use, and supplied slides snapped during vacations and at family events. Slide projectors were also widely used in educational and other institutional settings. Photographic film slides and projectors have mostly been replaced by image files on digital storage media shown on a projection screen by using a video projector or simply displayed on a large-screen video monitor. History A continuous-slide lantern was patented in 1881. It included a dissolving views apparatus.Sloane, T. O'Conor.
