Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block near-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs to prevent unwanted heating. There are also filters which are used in solid state video cameras to block IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the longer red wavelengths.
A camera lens is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Fujifilm Holdings Corporation, trading as Fujifilm, or simply Fuji, is a Japanese multinational conglomerate headquartered in Tokyo, Japan, operating in the realms of photography, optics, office and medical electronics, biotechnology, and chemicals.
In photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path, they are not magic. The filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a glass or plastic disk in a metal or plastic ring frame, which can be screwed into the front of or clipped onto the camera lens.
An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter.
An autofocus optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types.
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
The Nikon D2H is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003. It uses Nikon's own JFET-LBCAST sensor with a 4.1-megapixel resolution, and is optimised for sports and action shooting that require a high frame rate. In 2005, the D2H was replaced by the D2Hs, which added new features derived from the 12-megapixel D2X digital SLR. The D2Hs was discontinued after the introduction of the D300 and D3 models.
In photography, purple fringing is the term for an unfocused purple or magenta "ghost" image on a photograph. This optical aberration is generally most visible as a coloring and lightening of dark edges adjacent to bright areas of broad-spectrum illumination, such as daylight or various types of gas-discharge lamps.
A full-frame DSLR is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format. Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format. The full-frame DSLR is in contrast to full-frame mirrorless interchangeable-lens cameras, and DSLR and mirrorless cameras with smaller sensors, much smaller than a full 35 mm frame. Many digital cameras, both compact and SLR models, use a smaller-than-35 mm frame as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100, also used a smaller sensor.
Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ultraviolet radiation serve a number of scientific, medical or artistic purposes. Images may reveal deterioration of art works or structures not apparent under light. Diagnostic medical images may be used to detect certain skin disorders or as evidence of injury. Some animals, particularly insects, use ultraviolet wavelengths for vision; ultraviolet photography can help investigate the markings of plants that attract insects, while invisible to the unaided human eye. Ultraviolet photography of archaeological sites may reveal artifacts or traffic patterns not otherwise visible.
The Fujifilm FinePix S1 Pro was an interchangeable lens digital single-lens reflex camera introduced in January 2000. It was based on a Nikon F60 film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it had a Nikon F lens mount and so could use most lenses made for Nikon 35 mm cameras. It was autofocusing, had an electronically controlled focal plane shutter with speeds from 30 sec. to 1/2000 sec. and built-in exposure metering and pop-up flash. Its ISO film speed equivalents ranged from 320-1600. The camera is no longer in production, having been superseded by the Fujifilm FinePix S2 Pro in January 2002.
The Fujifilm FinePix S3 Pro is an interchangeable lens digital single-lens reflex camera introduced in February 2004. Its successor, the Finepix S5 Pro, was released on 25 September 2006. It is based on a Nikon F80 viewfinder, shutter, mirror-box and autofocus modules surrounded by a Fujifilm body that includes its own proprietary CCD image sensor and electronics, and a vertical grip shutter release. It has a Nikon F lens mount and can use most lenses made for 35 mm Nikon SLR cameras, but only with manual operation with Nikon AIS lenses, unusually for a digital SLR the S3 Pro can be used with a manual cable release.
The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan. It is fitted with a Sigma SA mount which takes Sigma SA lenses.
The FinePix S5 Pro is a digital single lens reflex camera introduced by Fujifilm on 25 September 2006 and since discontinued. It replaces the previous FinePix S3 Pro and keeps the Nikon F mount compatibility, including DX size lenses. It is based on the Nikon D200 body, and benefits from its improvements: 11-point autofocus, i-TTL flash, a bigger 2.5-inch (64 mm) LCD and a lithium-ion battery. It has a Super CCD 23×15.5 mm image sensor of the same configuration as its predecessor, with 6.17 million low sensitivity pixels and 6.17 million high sensitivity pixels to give a high dynamic range, and a boost to 3200 ISO.
Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the "VNIR".
The Fujifilm FinePix products are a line of digital cameras produced by Fujifilm. They include compact point and shoot models, tough, waterproof models, bridge digital cameras, digital SLRs and mirrorless cameras. Many use Fujifilm's proprietary Super CCD technology sensors and CMOS sensors for high-end models.
The Fujifilm X series is a line of digital cameras produced by Fujifilm. The series encompasses fixed lens and interchangeable lens mirrorless cameras and premium compact point-and-shoot cameras aimed at consumer, enthusiast and professional photographers. The X series is part of the larger FinePix range of digital cameras from Fujifilm.
The Fujifilm X100 is a series of digital compact cameras with a fixed prime lens. Originally part of the FinePix line, then becoming a member of the X series from Fujifilm, the X100 series includes the FinePix X100,X100S,X100T,X100F, and X100V. They each have a large image sensor and a 23 mm lens. All five cameras have received generally positive reviews.
