Nikon Coolpix 995
The Nikon Coolpix 995 was announced on April 25, 2001 to supersede the Coolpix 990 in the Nikon Coolpix series. Similar in appearance to the 990, changes include a switch to a high-impact plastic case for the lens half of the swivel body, a pop-up flash to reduce red-eye by moving the bulb away from the lens, an increase in zoom capability to 4x, CompactFlash Type II compatibility and use of the EN-EL1 rechargeable Li-Ion battery in place of the previous four AA batteries. The Coolpix 9xx series of cameras is noteworthy for the swivel style body. This allowed the user to rotate the lens with respect to the LCD screen and controls providing comfortable viewing in a wide range of shooting positions. The swivel body also allowed a physically much larger lens to be packaged into the camera with a wide telephoto range and exceptional macro capabilities. The internal lens does not use a pop out design and a fixed 28mm threaded lens mounting ring was included at the front. The diamete ...

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikkor
Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount. Nikko parent company brand, from which the Nikkor brand evolved. The ''Nikkor'' brand was introduced in 1932, a Westernised rendering of an earlier version ''Nikkō'' (日光), an abbreviation of the company's original full name ''Nippon Kōgaku'' ("Japan Optics"; 日本光学工業株式会社).The 75th Anniversary of NIKKOR Lenses'' (''Nikkō'' also means "sunlight" and is the name of a Japanese town.) In 1933, Nikon marketed its first camera lens under the Nikkor brand name, the "Aero-NIKKOR," for aerial photography. Nikon originally reserved the Nikkor designation for its highest-quality imaging optics, but in recent history almost all Nikon lenses are so branded. Notable Nikkor branded optics have included: * F-mount lenses for 35mm SLR and DSLR photography. For a full list see Nikon F-mount. * 1 mount lenses for Nikon CX format currently used by Nikon 1 series. * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Temperature
Color temperature is the color of light emitted by an idealized opaque, non-reflective body at a particular temperature measured in kelvins. The color temperature scale is used to categorize the color of light emitted by other light sources regardless of their temperature. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to yellow to white to bluish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature. Color temperatures over 5000 K are called "cool colors" (bluish) ...

2CR5
This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. For example, a CR123 battery is always LiMnO2 ('Lithium') chemistry, in addition to its unique size. The following tables give the common battery chemistry types for the current common sizes of batteries. See Battery chemistry for a list of other electrochemical systems. Cylindrical batteries Rectangular batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TFT LCD
A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in appliances including television sets, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in automobiles. History In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CompactFlash
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/ SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly. CompactFlash's popularity is declining as CFexpress is taking over. As of 2022, both Canon and Nikon newest high end cameras, e.g. the Canon EOS R5, Canon EOS R3, and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interface, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photomicrography
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromatic Aberration
In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image. Types There are two types of chromatic aberration: ''axial'' (''longitudinal''), and ''transverse'' (''lateral''). Axial aberration occurs when different wavelengths of light are focused at different distances from the lens (focus ''shift''). Longitudinal aberration is typical at long focal lengths. Transverse aberration occurs when different wavelengths are focused at different positions i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon Coolpix S4
The Coolpix S4 is a brand of digital camera produced by Nikon. Its image sensor is a CCD with 6.0 million pixels. It has a thin-film transistor liquid crystal display device with 110,000 pixels. The S4 incorporates Nikon's popular swivel design which allows the addition of a powerful Nikkor 10X Optical zoom lens, yet retain a compact form. Other features include D-Lighting and Face-priority AF. Nikon later released the Nikon Coolpix S10 which has a similar 10x swivel lens design as the S4, but with more advanced features such as vibration reduction and a lithium ion battery.

Nikon Coolpix 950
The Nikon Coolpix 950 was a digital camera released by Nikon in early 1999. The 950 model superseded the Coolpix 900 in the Nikon Coolpix series. The Coolpix 950 was a durable camera with swivel lens, magnesium body, a maximum resolution of 1600×1200 (1.92 Mpx), 3× optical zoom and a minimum focusing distance of 2 cm. It was in turn superseded by the Coolpix 990. The 950 incorporated improvements over the 900 such as a stronger swivel hinge, a magnesium case (except the plastic battery door) and increased sensor resolution. The 950's ability to capture directly in TIFF format was unusual for the time, although the file transfer time (depending on CF card write speed available at the time) could be over 30 seconds in this mode. The 950 came with a 8MB CF card, and the card could contain only 1 image file shot in the TIFF mode (~5.6MB). The maximum CF capacity for the 950 is 64MB. Other advanced features of the 950 included shutter and aperture priority modes and the abilit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
