Fujifilm in the context of Biomedical engineering

Instax (stylized as instax) is a brand of instant still cameras and instant films marketed by Fujifilm.

The first camera and accompanying film, the Instax Mini 10 and Instax Mini film, were released on November 10, 1998. The "Wide" film and first accompanying camera were released the following year. The Instax Square film and accompanying camera were released in 2017.

Dye coupler is present in chromogenic film and paper used in photography, primarily color photography. When a color developer reduces ionized (exposed) silver halide crystals, the developer is oxidized, and the oxidized molecules react with dye coupler molecules to form a dye in situ. The silver image is removed by subsequent bleach and fix processes, so the final image will consist of the dye image.

Dye coupler technology has seen considerable advancement since the beginning of modern color photography. Major film and paper manufacturers have continually improved the stability of the image dye by improving couplers, particularly since the 1980s, so that archival properties of images are enhanced in newer color papers and films. Generally speaking, dye couplers for paper use are given more emphasis on the image permanence than those for film use, but some modern films (such as Fujichrome Provia films) use variants of couplers that were originally designed for paper use to further improve the image permanence.

Roll film or rollfilm is any type of spool-wound photographic film protected from white light exposure by a paper backing. The term originated in contrast to sheet film. Confusingly, roll film was originally often referred to as "cartridge" film because of its resemblance to a shotgun cartridge.

The opaque backing paper allows roll film to be loaded in daylight. It is typically printed with frame number markings which can be viewed through a small red window at the rear of the camera. A spool of roll film is usually loaded on one side of the camera and pulled across to an identical take up spool on the other side of the shutter as exposures are made. When the roll is fully exposed, the take up spool is removed for processing and the empty spool on which the film was originally wound is moved to the other side, becoming the take up spool for the next roll of film.

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, X100V, and X100VI. They each have a large image sensor and a 23 mm lens (35 mm equivalent angle of view in full frame format). All six cameras have received generally positive reviews.

The Fujifilm FinePix X100 was initially shown at the Photokina show in September 2010 and was subsequently introduced in February 2011. It was the first model in the Fujifilm X-series of cameras and has since been joined by numerous models. It is superseded by the Fujifilm X100S.

An instant camera is a camera which uses self-developing film to create a chemically developed print shortly after taking the picture. Polaroid Corporation pioneered (and patented) consumer-friendly instant cameras and film, and were followed by various other manufacturers.

The invention of commercially viable instant cameras which were easy to use is generally credited to Edwin Land, the inventor of the model 95 Land Camera, widely considered the first commercial instant camera, in 1948, a year after he unveiled instant film in New York City.

Provia is a brand name for a pair of daylight-balanced color reversal films (slide film) produced by the Japanese film company Fuji film. It is currently available in one speed, 100/21°, marketed as Fujichrome Provia 100F Professional [RDP III],. An additional speed of 400/27°, marketed as Fujichrome Provia 400X Professional [RXP], was previously available.
