Tri-X
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. Overview Introduced around 1940 in sheets rated at ASA daylight 200 and tungsten 160, it was one of Kodak's first high-speed (for the time) black and white films. Tri-X was released in 35 mm and 120 formats in 1954. Currently it is available in two speeds, ISO 320/26° (320TXP) and 400/27° (400TX). Tri-X 400 is the more common of the two, available in 24- and 36-exposure rolls of 35 mm and rolls of 120 as well as 50 and 100 ft bulk rolls of 35 mm. Tri-X 320 is available in 4×5", 5×7", and 8×10" sheets. Tri-X 400 is usually rated at ISO 400 when processed in standard developers and remains among the fastest black and white films today.

Kodak Alaris
Kodak Alaris is a British manufacturer and marketer of traditional photographic supplies (including film, paper, and processing chemicals), hardware and software for digital imaging and information management, and retail printing kiosks. The company is headquartered in Hemel Hempstead, Hertfordshire. The company shares ownership of the Kodak brand with the Eastman Kodak Company (usually known simply as Kodak). History In 2012, Kodak filed for bankruptcy after a years-long decline in the company's core business related to film photography. As part of the bankruptcy, Kodak faced a $2.8 billion claim by the UK Kodak Pension Plan (KPP). The claim was resolved and Kodak Alaris was formed when KPP paid $325 million for Kodak's personalized imaging and document imaging businesses. KPP continues to control Kodak Alaris as a privately held company through Kodak Alaris Holdings Limited. In 2014, the company appointed Ralf Gerbershagen as CEO. Also in 2014, Mark Elliott was named Chairm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems His ...

During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its " Kodak moment" tagline entered the common lexicon to describe a personal event that deserved to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilford HP
HP is a cubic-grain black-and-white film from Ilford Photo with a long history. It originated as Hypersensitive Panchromatic plates in 1931. Since then it has progressed through a number of versions, with HP5 plus (HP5+ for short) being the latest. The main competitor of Ilford HP5 Plus is Kodak Tri-X Tri-X is a black and white photographic film produced by the Eastman Kodak Company.

HP3 went through two speed changes in its history, but only one actual change to the emulsion. In 1960 the 200 ISO/ASA emulsion was relabeled as 400 ISO/ASA with no change to the product. The 200 ISO/ASA speed included an exposure safety margin, but with improvements in light meters this was deemed unnecessary, thus the speed was revised up to 400 ISO/ASA. On September 23, 2005, Ilford reintroduced its black-and-white si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodak T-MAX
Kodak Professional T-MAX Film is a continuous tone, panchromatic, tabular-grain black and white negative film originally developed and manufactured by Eastman Kodak since 1986. It is still manufactured by Eastman Kodak but distributed and marketed by Kodak Alaris, as with other products under ''Kodak Professional'' banner. It is sold in three speeds: ISO 100, ISO 400 and 3200 which is a multi-speed film. To easily identify the emulsion, for each film speed, one letter in the edge marking is altered with ISO 100 being TMX, ISO 400 being TMY and ISO 3200 being TMZ. Details Eastman Kodak still manufactures the films but following its Chapter 11 bankruptcy in 2012, responsibility for distribution and marketing, as with other products under ''Kodak Professional'' brand, was given to Kodak Alaris, a separate company controlled by the Kodak UK pension fund. It is sold in three speeds: 100 (TMX), 400 (TMY-2) and 3200 (TMZ). The 100 and 400 speeds are given as ISO numbers, but the ...

Black And White
Black-and-white (B&W or B/W) images combine black and white in a continuous spectrum, producing a range of shades of grey. Media The history of various visual media began with black and white, and as technology improved, altered to color. However, there are exceptions to this rule, including black-and-white fine art photography, as well as many film motion pictures and art film(s). Photography Contemporary use Since the late 1960s, few mainstream films have been shot in black-and-white. The reasons are frequently commercial, as it is difficult to sell a film for television broadcasting if the film is not in color. 1961 was the last year in which the majority of Hollywood films were released in black and white. Computing In computing terminology, ''black-and-white'' is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of ...

Photographic Film
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin photographic emulsion, emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and image resolution, 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 (photography), 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 photographic processing, developed into a visible photograph. In addition to visible light, all films are sensitive to ultraviolet light, X-rays, gamma rays, and particle radiation, high-energy particles. Unmodified silver halide crys ...

Sheet Film
Sheet film is large format and medium format photographic film supplied on individual sheets of acetate or polyester film base rather than rolls. Sheet film was initially supplied as an alternative to glass plates. The most popular size measures ; smaller and larger sizes including the gigantic have been made and many are still available today. Using sheet film To use sheet film, the photographer places a sheet of film, emulsion side out, into a film holder in the dark, and closes the dark slide over the loaded film. Next, the holder is inserted into a large-format camera, and the dark slide is removed from the holder. The exposure is made, the dark slide is replaced, and the film holder is removed from the camera. Notches Sheet films have notches cut into one short side. This makes it simple to determine which side is the emulsion, when the film is hidden from sight (in the darkroom, or inside a changing bag). When holding the sheet in "portrait" orientation (short si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photojournalism
Photojournalism is journalism that uses images to tell a news story. It usually only refers to still images, but can also refer to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (such as documentary photography, social documentary photography, war photography, street photography and celebrity photography) by having a rigid ethical framework which demands an honest but impartial approach that tells a story in strictly journalistic terms. Photojournalists contribute to the news media, and help communities connect with one other. They must be well-informed and knowledgeable, and are able to deliver news in a creative manner that is both informative and entertaining. Similar to a writer, a photojournalist is a journalist, reporter, but they must often make decisions instantly and carry camera, photographic equipment, often while exposed to significant obstacles, among them immediate physical danger, bad weather, large crow ...

Gelatin-silver Process
The gelatin silver process is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image. A suspension of silver salts in gelatin is coated onto a support such as glass, flexible plastic or film, baryta paper, or resin-coated paper. These light-sensitive materials are stable under normal keeping conditions and are able to be exposed and processed even many years after their manufacture. This was an improvement on the collodion wet-plate process dominant from the 1850s–1880s, which had to be exposed and developed immediately after coating. History The gelatin silver process was introduced by Richard Leach Maddox in 1871 with subsequent considerable improvements in sensitivity obtained by Charles Harper Bennett in 1878. Gelatin silver print paper was made as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
