Nikon D1
The Nikon D1 is a digital single-lens reflex camera (DSLR) made by Nikon Corporation introduced on June 15, 1999. It featured a 2.7-megapixel image sensor, 4.5-frames-per-second continuous shooting, and accepted the full range of Nikon F-mount lenses. The camera body strongly resembled the F5 and had the same general layout of controls, allowing users of Nikon film SLR cameras to quickly become proficient in using the camera. Autofocus speed on the D1 series bodies is extremely fast, even with "screw-driven" AF lenses. Although Nikon and other manufacturers had produced digital SLR cameras for several years prior, the D1 was the first professional digital SLR that displaced Kodak's then-undisputed reign over the professional market. Unusual for a DSLR, the D1 uses the NTSC color space instead of the conventional sRGB or Adobe RGB color spaces. The resulting color on the D1 can be a bit unorthodox, but methods of correcting and/or compensating for the color problem are readily a ...

Kodak
The Eastman Kodak Company (referred to simply as Kodak ) is an American public company that produces various products related to its historic basis in analogue photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. Kodak provides packaging, functional printing, graphic communications, and professional services for businesses around the world. Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. It is best known for photographic film products. Kodak was founded by George Eastman and Henry A. Strong on May 23, 1892. During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its " Kodak moment" tagline entered the common lexicon to describe a personal event that deserved to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameras Introduced In 1999
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 cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal-to-noise Ratio
Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. SNR, bandwidth, and channel capacity of a communication channel are connected by the Shannon–Hartley theorem. Definition Signal-to-noise ratio is defined as the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): : \mathrm = \frac, where is average power. Both signal and noise power must be measured at the same or equivalent points in a system, and within the same system bandwidth. Depending on whether the signal is a constant () or a random variable (), the signal-to-noise ratio for random noise becomes: : \mathrm = \frac where E refers to the expected value, i.e. in this case ...

Photosite
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.

Kodak DCS 400 Series
The Kodak DCS 400 series was a series of Nikon based digital SLR cameras with sensor and added electronics produced by Eastman Kodak. It was part of Kodak's DCS (Digital Camera System) line. The cameras in this series include the 1.5-megapixel DCS 420 (introduced in August 1994), the 1.5-mpx DCS 410 (introduced in 1996), and the 6.2-mpx DCS 460 (introduced in March 1995). In addition, Kodak sold a version of the back from the DCS 460 adapted for medium format bodies as the DCS 465. Kodak also made a camera especially for Associated Press. It was called NC2000 (based on the Nikon N90/F90), later upgraded to NC2000e (based on the Nikon N90s/F90x) using many of the same components as were used for the DCS 400 series. Kodak also used the imaging component and electronics of the DCS 420 to produce a digital version of the Nikonos underwater camera, which was produced in limited numbers for military and scientific applications as the Kodak DCS 425. In addition to the standard colour ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodak DCS
The Kodak Digital Camera System is a series of digital single-lens reflex cameras and digital camera backs that were released by Kodak in the 1990s and 2000s, and discontinued in 2005. They are all based on existing 35mm film SLRs from Nikon, Canon and Sigma. The range includes the original Kodak DCS, the first commercially available digital SLR. History In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which uses a Fairchild 100 x 100 pixel CCD. By 1986 Kodak had developed a sensor with 1.4 million pixels. A number of other inventions were made to increase usability, including improvements in sensor technology, the first raw image format DCR, and usable host software. The original Kodak DCS was launched in 1991, and is based on a stock Nikon F3 SLR with digital components. It uses a 1.3-megapixel Kodak KAF-1300 sensor, and a separate shoulder-mounted processing and storage unit. The DCS 200 series of 1992 condenses the storage unit into a module whic ...

Adobe RGB
The Adobe RGB (1998) color space or opRGB is a color space developed by Adobe Systems, Inc. in 1998. It was designed to encompass most of the colors achievable on CMYK color printers, but by using RGB primary colors on a device such as a computer display. The Adobe RGB (1998) color space encompasses roughly 50% of the visible colors specified by the CIELAB color space – improving upon the gamut of the sRGB color space, primarily in cyan-green hues. It was subsequently standardized by the IEC as IEC 61966-2-5:1999 with a name opRGB (optional RGB color space) and is used in HDMI. Historical background Beginning in 1997, Adobe Systems was looking into creating ICC profiles that its consumers could use in conjunction with Photoshop's new color management features. Since not many applications at the time had any ICC color management, most operating systems did not ship with useful profiles. Lead developer of Photoshop, Thomas Knoll decided to build an ICC profile around specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRGB
sRGB is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the World Wide Web. It was subsequently standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999. sRGB is the current defined standard colorspace for the web, and it is usually the assumed colorspace for images that are neither tagged for a colorspace nor have an embedded color profile. sRGB essentially codifies the display specifications for the computer monitors in use at that time, which greatly aided its acceptance. sRGB uses the same color primaries and white point as ITU-R BT.709 standard for HDTV, a transfer function (or gamma) compatible with the era's CRT displays, and a viewing environment designed to match typical home and office viewing conditions. An amendment of the IEC 61966-2-1 standard document that defines sRGB includes the definition of a number of variants including sYCC, which is a ...

Nikon F5
The Nikon F5 is a 35 mm film-based single-lens reflex camera body manufactured by Nikon from 1996 through 2004. It was the fifth in Nikon's professional film camera line, which began in 1959 with the Nikon F. It followed the Nikon F4 of 1988, which had introduced in-body autofocus to Nikon's professional line. The F5 was in turn succeeded by the Nikon F6, as well as Nikon's parallel range of professional digital SLRs, beginning with the Nikon D1. Design Important advances in the F5 included: * Nikon 3-D color matrix meter (the F4 had introduced multi-segment matrix metering to the F series, but color sensing was new). * A self-diagnostic and self-adjusting shutter. * A mirror-balance system that reduced camera shake. * Electronically controlled exposure times from 1/8000 second to 30 seconds. * Built-in 8 frame per second motor drive (up from 5.7 frame/s on the F4). * 1/300 second flash sync (up from 1/250 on the F4). However, at 1/300 second, flash units could not use their ful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Single-lens Reflex Camera
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...
