Nikon D700
The Nikon D700 is a professional-grade full-frame digital single-lens reflex camera introduced by the Nikon Corporation in July 2008 and manufactured in Japan. It uses the same 12.1-megapixel "FX" CMOS image sensor as the Nikon D3, and is Nikon's second full-frame digital SLR camera. The D700's full-frame sensor allows the use of F-mount (FX) lenses to their fullest advantage, with almost no crop factor. When a cropped DX lens is mounted on the D700, either the DX-sized portion, or the (vignetted) FX-sized portion of the camera's sensor can be used. The D700 has a built in autofocus motor for all Nikon autofocus- lenses, includes CPU and metering for older Nikon F-mount AI/AI-S lenses, and supports PC-E lenses. The D700 bears a physical similarity to the Nikon D300, which uses the same MB-D10 battery pack and EN-EL3e battery. As of 2012, the Nikon D3X, the D3/D3s, D4 and D700 were the only Nikon DSLR models manufactured in Japan. It was discontinued on August 24, 2012. Fea ...

Single-lens Reflex Camera
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Nikon D3X
The Nikon D3X is a 24.4-megapixel professional-grade full-frame digital single-lens reflex camera (DSLR) announced by the Nikon Corporation on 1 December 2008. The D3X is the third camera in Nikon's line to offer a full-frame sensor, following the D3 and D700. As Nikon's new flagship model, it augments the Nikon D3S, Nikon's high-speed professional model, and while the D3S retains advantages in terms of high ISO performance and higher frame rate, the D3X offers a dramatic increase in resolution and image detail. The D3S and D3X follow the earlier Nikon D1, Nikon D2H, Nikon D2Hs, Nikon D2X, Nikon D2Xs, and Nikon D3 as the company's top-of-the-line DSLRs intended for professional photographers, which in turn share a lineage with the Nikon F through Nikon F6 series of film SLRs. Features It otherwise offers nearly all the features of the D3S, including robust weather-sealed alloy-body construction and a built-in vertical grip. Its Nikon EXPEED image processor features automatic ...

Vignetting
In photography and optics, vignetting is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word ''vignette'', from the same root as ''vine'', originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait that is clear at the center and fades off toward the edges. A similar effect is visible in photographs of projected images or videos off a projection screen, resulting in a so-called "hotspot" effect. Vignetting is often an unintended and undesired effect caused by camera settings or lens limitations. However, it is sometimes deliberately introduced for creative effect, such as to draw attention to the center of the frame. A photographer may deliberately choose a lens that is known to produce vignetting to obtain the effect, or it may be introduced with the use of special filters or post-processing procedures. When using superzoom lenses, vignetting may occur all alo ...

Capture NX
Capture NX is a photo editing computer program developed by Nik Software in partnership with Nikon for macOS and Microsoft Windows. In September 2012, Google acquired Nik Software, but Capture NX has remained a Nikon software and is advertised as a Nikon product. In July 2014, Nikon released a new software Capture NX-D to replace Capture NX 2. As such, Nikon D810 is the first camera to support only Capture NX-D. Capture NX-D was developed based on SILKYPIX Developer Studio and does not contain the U-Point technology from Nik Software. Since February 2020, the current release of the software does not install on Windows 7 anymore. On June 6, 2022, Nikon announced that Capture NX 2 and Capture NX-D will be discontinued and replaced by NX Studio. Download links for both programs were removed on June 30, 2022. Features of both Capture NX products *Complete raw image format support from import to export (for supported cameras), including Nikon's own RAW format ''NEF'' (Nikon Elec ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

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 ...

Nikon Lenses
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a flange to focal plane distance of 46.5mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital SLR cameras. History The Nikon F-mount is one of only two SLR lens mounts (the other being the Pentax K-mount) which were not abandoned by their associated manufacturer upon the introduction of autofocus, but rather extended to meet new requirements related to metering, autofocus, and aperture control. The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history. Over 400 different Nikkor lenses are compatible with the system. The F-mount is also popular in scientific and industria ...

Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras. History Before the development of microelectronics and electronic display devices, only optical viewfinders existed. Direct optical viewfinders Direct viewfinders are essentially miniature Galilean telescopes; the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. A declining minority of point and shoot cameras use them. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. The error varies with distance, being ...

Image Processor
An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for image processing, in digital cameras or other devices. Image processors often employ parallel computing even with SIMD or MIMD technologies to increase speed and efficiency. The digital image processing engine can perform a range of tasks. To increase the system integration on embedded devices, often it is a system on a chip with multi-core processor architecture. Function Bayer transformation The photodiodes employed in an image sensor are color-blind by nature: they can only record shades of grey. To get color into the picture, they are covered with different color filters: red, green and blue (RGB) according to the pattern designated by the Bayer filter - named after its inventor. As each photodiode records the color information for exactly one pixel of the image, withou ...

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. Etymology The w ...
