Mamiya RB67 - Dos 120
is a Japanese company that manufactures high-end cameras and other related photographic and optical equipment. With headquarters in Tokyo, it has two manufacturing plants and a workforce of over 200 people. The company was founded in May 1940 by camera designer Seiichi Mamiya () and financial backer Tsunejiro Sugawara. History Mamiya originally achieved fame for its professional medium-format film cameras such as the Mamiya Six and the Mamiya Press series. It later developed the industry workhorse Mamiya RB67, RB67 series, the Mamiya RZ67, RZ67, the Mamiya 645, 645 and the twin-lens reflex Mamiya C-series, used by advanced amateur and professional photographers. Many Mamiya models over the past six decades have become collectors' items. The earliest Mamiya Six medium-format folding camera, the 35 mm Mamiya-Sekor 1000DTL, the lightweight 35 mm Mamiya NC1000, the 6Ć6 cm medium-format C series of interchangeable-lens twin-lens reflex (TLR) cameras, and the press c ...

Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Emulsion
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms ''colloid'' and ''emulsion'' are sometimes used interchangeably, ''emulsion'' should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working. Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase. Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the continuous phase. Multiple emulsions are also pos ...

MAHOGANY DOUBLE DARK SLIDES, TO FIT LANCASTER Camera Supply , 1895-1902 PLATE CAMERA (17036203928)
Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164ā165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species. Description The three species are: *Honduran or big-leaf mahogany (''Swietenia macrophylla''), with a range from Mexico to southern Amazonia in Brazil, the most widespread species of mahogany and the only genuine mahogany species commercially grown today.

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 ...

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. The founder's son, Arvid Viktor Hasselblad, was interested in photography and started the phot ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

View Camera
A view camera is a large-format camera in which the lens forms an inverted image on a ground-glass screen directly at the film plane. The image is viewed and then the glass screen is replaced with the film, and thus the film is exposed to exactly the same image as was seen on the screen. This type of camera was first developed in the era of the daguerreotypeStroebel, L. D. (1986). ''View Camera Technique'', 5th ed., p. 212. Boston: Focal Press. (1840sā1850s) and is still in use today, some with various drive mechanisms for movements (rather than loosen-move-tighten), more scale markings, and/or more spirit levels. It comprises a flexible bellows that forms a light-tight seal between two adjustable ''standards'', one of which holds a lens, and the other a ground glass or a photographic film holder or a digital back.Stroebel (1986). p. 2. There are three general types, the rail camera, the field camera, and others that don't fit into either category. The bellows is a flexi ...

Reisekamera
The Reisekamera, meaning a "travel camera", is a large-format wooden bellows tailboard view camera of almost standardised design, unlike the much lighter and more flexible field camera, but not as cumbersome as the studio camera. A sturdy tripod is always brought along, but it might just as well be placed on a tabletop. It has equally sized rectangular front and back panels on a full-width double-extension baseboard that is hinged near the front. The front panel, holding the lens plate, has horizontal and vertical movements, while the back is tilt-suspended on brass standards running on brass tracks on either side of the baseboard, providing rack and pinion focusing on the film plane. An almost non-tapering calico double-extension bellows is employed; allowing the projected image to freely reach the photographic plate regardless of lens offset position. The camera folds flat, after the back panel is brought forward to the lens panel, by folding the hinged base board up, and thus co ...
