Scanner Camera
A scanning back is a type of digital camera back. Digital imaging devices typically use a matrix of light-sensitive photosensors, such as CCD or CMOS technologies. These sensors can be arranged in different ways, like a Bayer filter, where each row captures RGB components, or using one full-sized layer for each color, such as the Foveon X3 sensor. A digital scan back takes a similar approach to the second type of photosensor, but instead of using one matrix for each component, it uses one array per component. This translates to a 3xN sensor matrix, where N is typically a large number (between 5,000 for earlier models and 15,000 for newer models), which is then placed vertically in a holder. To take an image, the sensor travels the x axis, taking one exposure per point. Advantages The main advantages of this technology are the extremely high image quality and the huge resulting files. This translates to very accurate color reproduction, because every pixel is measured individuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Camera Back
A digital camera back is a device that attaches to the back of a camera in place of the traditional negative film holder and contains an electronic image sensor. This lets cameras that were designed to use film take digital photographs. These camera backs are generally expensive by consumer standards (US$5,000 and up) and are primarily built to be attached on medium- and large-format cameras used by professional photographers. Types Two sensor back types are commonly used: single shot back (non-scanning) and scan back. Some backs, primarily older ones, require multiple exposures to capture an image; generally one each for red, green, and blue. These are called multi-shot or 3-shot backs. As technology advanced single-shot backs became more practical; by 2008 most backs manufactured were single-shot. Early backs had to be used tethered by a cable to a controlling computer that would store the images they took. Newer models added the ability to store the photos inside the bac ...

Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Pentacon
Pentacon is the company name of a camera manufacturer in Dresden, Germany. The name Pentacon is derived from the brand Contax of Zeiss Ikon Kamerawerke in Dresden and Pentagon, as a Pentaprism for Single-Lens Reflex (SLR) cameras was for the first time developed in Dresden. The cross section of this prism has a pentagonal shape. Pentacon is best known for producing the SLR cameras of the Praktica-series as well as the medium format camera Pentacon Six, the Pentacon Super and various cameras of the Exa series. Pentacon also produced slide projectors. History In 1959 several Dresden camera manufacturers, among them VEB Kamerawerke Freital, were joined to create Volkseigener Betrieb Kamera- und Kinowerke Dresden, which was renamed in 1964 to VEB Pentacon Dresden. In 1968, VEB Feinoptisches Werk Görlitz was integrated into VEB Pentacon. Accordingly, the former Meyer-Optik Görlitz lenses were now renamed to ”Pentacon“ . After German reunification in 1990 Pentacon, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panoscan
A rotating line camera is a digital camera that uses a linear CCD array to assemble a digital image as the camera rotates. The CCD array may consist of three sensor lines, one for each RGB color channel. Advanced rotating line cameras may have multiple linear CCD arrays on the focal plate and may capture multiple panoramic images during their rotation. Line-scan technology is capable of capturing data extremely fast, and at very high image resolutions. Usually under these conditions, resulting collected image data can quickly exceed 100 MB in a fraction of a second. Line-scan-camera–based integrated systems, therefore are usually designed to streamline the camera's output in order to meet the system's objective, using computer technology which is also affordable. Line-scan cameras intended for the parcel handling industry can integrate adaptive focusing mechanisms to scan six sides of any rectangular parcel in focus, regardless of angle, and size. The resulting 2-D captured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Better Light
Better Light, Inc. was an American company that manufactured digital backs for large format film cameras. It was based in San Carlos, California. The Better Light scan back was a device designed to make it possible to capture digital photographs using traditional 4x5 large format film view cameras, copy stands, and microscopes by replacing the 4x5 film holders that they used. The Better Light utilized a high-resolution line scanner that scanned the image plane in place of where a sheet of 4x5 film traditionally went. This action was similar to how a desktop scanner works. This scan took time, so could only be used for still objects. This approach was in contrast to sensors used in contemporary digital cameras that capture the entire image at once. The primary benefit of the Better Light system was that it did not need to use a Bayer filter to record color information so avoided the need to interpolate color data. Current Pixelshift technology achieves the same result in Bayer filt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slit-scan Photography
The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed. More generally, "slit-scan photography" refers to cameras that use a slit, which is particularly used in scanning cameras in panoramic photography. This has numerous applications. This article discusses the manual artistic technique.{{cite web, url=https://petapixel.com/2017/10/18/role-slit-scan-image-science-art/, title=The Role of the Slit-Scan Image in Science and Art, date=18 October 2017, website=petapixel.com Use in cinematography Originally used in static photography to achieve blurriness or deformity, the slit-scan technique was perfected for the creation of spectacular animations. It enables the cinematographer to create a psychedelic flow of colors. Though this type of effect is now often created through computer animation, slit-scan is a mechanical technique. Jo ...

Scanography
Scanography (also spelled scannography), more commonly referred to as scanner photography, is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed "photo" scanner with a CCD (charge-coupled device) array capturing device. Fine art scanography differs from traditional document scanning by using atypical objects, often three-dimensional, as well as from photography, due to the nature of the scanner's operation. History The process of creating art with a scanner can be as simple as arranging objects on the scanner and capturing the resulting image; in fact, some early artists in the field worked with photocopiers to capture and print in a single step, resulting in the field of Xerox art. Artist Sonia Landy Sheridan, artist in residence at 3M and founder of the ''Generative Systems'' program at the Art Institute of Chicago was one of the first to exploit this ability in 1968, altering the variables of the photocopying pro ...
