Film stock is an analog medium that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum.
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of 35 mm (1.4 in) loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'.
110 is a cartridge-based film format used in still photography. It was introduced by Kodak in 1972. 110 is essentially a miniaturized version of Kodak's earlier 126 film format. Each frame is 13 mm × 17 mm, with one registration hole. Cartridges with 12, 20, or 24 frames are available on-line. Production variations sometimes have allowed for an additional image.
Disc film is a discontinued still-photography film format that was aimed at the consumer market. It was introduced by Kodak in 1982.
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.
Velvia is a brand of daylight-balanced color reversal film produced by the Japanese company Fujifilm. The name is a portmanteau of "Velvet Media", a reference to its smooth image structure. The original incarnation of the film was called "Velvia for Professionals", known as RVP, a classification code meaning "Reversal/Velvia/Professional series". It is known for its extremely high level of color saturation and image quality.
Instant film is a type of photographic film that was introduced by Polaroid Corporation to produce a visible image within minutes or seconds of the photograph's exposure. The film contains the chemicals needed for developing and fixing the photograph, and the camera exposes and initiates the developing process after a photo has been taken.
Kodak Ektar is a professional color negative film introduced in 2008, designed for nature, outdoors, fashion, and product photography. The film offers ultra-fine grains, ultra-vivid colors, and high saturation, and is available in ISO 100 only.
Provia is a brandname for a pair of daylight-balanced color reversal films produced by the Japanese film company Fujifilm. 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.
Polaroid Type 55 film is a black-and-white peel-apart Polaroid film that yields both a positive print and a negative image that can be used to create enlargements.
Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography, which uses electronic sensors to record images to digital media. Analog electronic photography was sometimes used in the late 20th century but soon died out.
Tri-X is a black and white photographic film produced by the Eastman Kodak Company. Since 2013 it is distributed by Kodak Alaris which controls the Kodak Professional product line under which it is grouped. The combination of hand held cameras and high speed Tri-X film was transformative for photojournalism and for cinema.
Instax is a brand of instant still cameras and instant films marketed by Fujifilm.
Fujicolor Pro was a line of professional color negative films from Japanese company Fujifilm introduced in 2004 for weddings, portraits, fashion and commercial photography. It originally comprised four emulsions: Pro 160S, Pro 160C, Pro 400H and Pro 800Z. Its main competitor was Kodak Portra.
Kodak Portra is a family of daylight-balanced professional color negative films originally introduced in 1998 made mainly for portrait and wedding applications. They are successors of the professional Vericolor films, which succeeded Ektacolor films earlier. The films are available in three speeds — 160, 400, and 800 ISO — with the 160 and 400 speed formerly available as "natural color" (NC) and "vivid color" (VC) varieties before the 2011 update.
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. Film is typically segmented in frames, that give rise to separate photographs.
Neopan was originally a family of black-and-white films from Japanese manufacturer Fujifilm for both professional and amateur use. The range now only comprises one film; Neopan ACROS 100 II, a traditional silver halide black and white film re-launched in 2019 and currently sold worldwide.
