Kodak 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. Push ...

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] |
Push Processing
Push processing in photography, sometimes called uprating, refers to a film developing technique that increases the effective sensitivity of the film being processed. Push processing involves developing the film for more time, possibly in combination with a higher temperature, than the manufacturer's recommendations. This technique results in effective overdevelopment of the film, compensating for underexposure in the camera. Visual characteristics Push processing allows relatively insensitive films to be used under lighting conditions that would ordinarily be too low for adequate exposure at the required shutter speed and aperture combination. This technique alters the visual characteristics of the film, such as higher contrast, increased grain and lower resolution. Saturated and distorted colours are often visible on colour film that has been push processed. ''Pull processing'' involves overexposure and underdevelopment, effectively decreasing the sensitivity of the proce ... [...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. 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 cam ... 400. 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 ...

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 ...

Panchromatic Film
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As naturally prepared, a silver halide photographic emulsion is much more sensitive to blue and UV light than to green and red wavelengths. The German chemist Hermann W. Vogel found out how to extend the sensitivity into the green, and later the orange, by adding sensitising dyes to the emulsion. By the addition of erythrosine the emulsion could be made orthochromatic while some cyanine derivatives confer sensitivity to the whole visible spectrum making it panchromatic. However, his technique was not extended to achieve a fully panchromatic film until the early 1900s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stand Development
Stand development is a photographic development process where film is left in a very dilute developing solution for an extended period of time, with little or no agitation. The technique dates back to at least the 1880s, and results in fine grain, increased perceived sharpness, and smooth tonality, but is time-intensive and runs the risk of producing certain processing defects. Process In traditional film development, film is processed in concentrated development fluid for a brief period, typically 8 to 12 minutes. During this period the developing fluid is agitated, often by inverting the development tank several times every few minutes. This has the effect of spreading the developing fluid evenly over the surface of the film and preventing localised overdevelopment. Stand development instead uses a very dilute solution of developer, often one part developer to fifty or one hundred parts water. There is almost no agitation beyond initial mixing, and developing times are greatly i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Color Temperature
Color temperature is the color of light emitted by an idealized opaque, non-reflective body at a particular temperature measured in kelvins. The color temperature scale is used to categorize the color of light emitted by other light sources regardless of their temperature. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to yellow to white to bluish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature. Color temperatures over 5000 K are called "cool colors" (bluish) ...

135 Film
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 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'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

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 ...
