Tilt (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. (1840s–1850s) 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 flexib ...

Image Sensor
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging. The two main types of electronic image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor). Both CCD and CMOS sensors are based on metal–oxide–semiconductor (MOS) technology, with CCDs based on MOS capacitors and CMOS sensors based on M ...

Americas
The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes basin, Mississippi, and La Plata. Since the Americas extend from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rain forests in Central America and South America. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago. A second migration of Na-Dene speakers followed later ...

Sheet Film
Sheet film is large format and medium format photographic film supplied on individual sheets of acetate or polyester film base rather than rolls. Sheet film was initially supplied as an alternative to glass plates. The most popular size measures ; smaller and larger sizes including the gigantic have been made and many are still available today. Using sheet film To use sheet film, the photographer places a sheet of film, emulsion side out, into a film holder in the dark, and closes the dark slide over the loaded film. Next, the holder is inserted into a large-format camera, and the dark slide is removed from the holder. The exposure is made, the dark slide is replaced, and the film holder is removed from the camera. Notches Sheet films have notches cut into one short side. This makes it simple to determine which side is the emulsion, when the film is hidden from sight (in the darkroom, or inside a changing bag). When holding the sheet in "portrait" orientation (short si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goerz (company)
C. P. Goerz was founded in 1886 by Carl Paul Goerz. Originally, it made geometrical drawing instruments for schools. From 1888 it made cameras and photographic lenses. During the First World War, Goerz's main production was for the German and Austrian military. Goerz is known primarily for Anschütz strut-folding cameras, Dagor and Tengor lenses, Tenax cameras (later continued by Zeiss Ikon) and Minicord subminiature cameras. C. P. Goerz also made a series of telescopic sights for sporting rifles that saw some use during the shortage of military sniping rifles experienced during the early stages of the trench warfare that was to characterise much of the First World War. In 1895 Goerz founded a branch in New York that was to become the C. P. Goerz American Optical Company in 1905. This company continued to operate independently in the USA until 1972. In 1908, Goerz Photochemisches Werk GmbH was founded in Zehlendorf, Berlin. This company produced roll film and film for the movie ...

Process Camera
A process camera is a specialised form of camera used for the reproduction of graphic material. Before the advent of color scanners, color process work was undertaken by the process camera, by a skilled operator. This was achieved by using various filters to produce a set of 4 film separations, cyan, magenta, yellow and Black (CMYK), this in turn was usually color corrected by another tradesman called a color retoucher (this was the era before photoshop). After the introduction of color scanners in the 1970s, the process camera was gradually only used for monochrome line-work or less often monochrome tone-work. The original artwork was photographed and the negatives produced were eventually used to production of printing plates. This task was completed by another skilled tradesman called a 'film make-up planner'. Who would use a contact frame to photograph the various film layers they had created containing masked tints, text in film form and the separations produced by the process ...

Macrophotography
Macro photography (or photomacrography or macrography, and sometimes macrophotography) is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size (though ''macrophotography'' also refers to the art of making very large photographs). By the original definition, a macro photograph is one in which the size of the subject on the Negative (photography), negative or image sensor is life size or greater. In some senses, however, it refers to a finished photograph of a subject that is greater than life size. The ratio of the subject size on the film plane (or sensor plane) to the actual subject size is known as the reproduction ratio. Likewise, a macro lens is classically a lens capable of reproduction ratios of at least 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1. Apart from technical photography and film-based ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinar
Sinar Photography AG is a Swiss company based in Zurich manufacturing specialized high-resolution view cameras for studio, reproduction, landscape and architecture photography. Sinar's view-cameras allow both the lens and the film back or sensor back to move in rotation or linearly in any direction (up/down, left/right, front back linearly, and pitch yaw tilt rotations), thus allowing precise image alignment corrections. The cameras are thus often used in advertising, document reproduction, product and architectural photography, where correctly vertical image lines, fine focus accuracy, and extra details are wanted. The name SINAR is explained by the company itself as "Still, Industrial, Nature, Architectural and Reproduction photography" in the English version of the April 2011 press release. Other versions of the names were also used, with the S for studio, Sache, or science. In the Indonesian language, "Sinar" translates into English as "Light Ray". Founding The business r ...

Monorail Camera
Monorail cameras are view cameras with lens mount, bellows, and interchangeable viewing and film backs all fitted along a rigid rail along which they can slide until locked into position. They can take sheet film in large sizes, and since the advent of digital photography can take a digital back. They are used to take very high-quality photographs of static subjects on large film, or at high digital image resolution, and capable of much enlargement with good quality. They have many camera movements for image control. The image is usually viewed on a ground-glass screen in the film plane; after the scene has been composed, the ground glass is replaced by the film, and the exposure made. Monorail cameras rarely have any other viewfinder than the ground glass. Details Virtually any lens can be fitted, and backs for sheet film, rollfilm, digital back and Polaroid backs. For some uses with long exposures, or flash lighting; a shutter is unnecessary; removing a lens cap to expose t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
