Tri-X [[panchromatic film]] was once one of the most popular films used by photojournalists and many amateurs. It was manufactured by Eastman Kodak in the US, Kodak Canada, and Kodak Ltd in the UK. Kodak data-sheets once recommended different processing times depending on where the film was manufactured. Its sales declined in the 1970s and 1980s due to the falling price and increasing popularity of color film. Since the advent of digital photography, Tri-X has all but fallen out of use in newspaper journalism, though it remains popular in documentary journalism.

An early change in ASA (ISO) speed from 200 to 400, around 1960, was due to a change in the ASA standard rather than the film.

Tri-X also exists as a reversal film for the 16mm and Super-8 cine film formats. The speed for tungsten lighting (3200 K) is ISO 160 and for daylight ISO 200 when processed as reversal. It can also be processed as a negative at a small loss of speed while the grain will be slightly increased.

Tri-X is a black-and-white photographic film produced by Eastman Kodak Company and remains the world's best selling black and white film.[1] It is appreciated for its wide exposure latitude and classic grain structure.[2] The combination of smaller 35mm cameras and high speed Tri-X film was transformative for photojournalism.[3]

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 35mm and 120 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 35mm. 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 processing Tri-X to a higher "exposure index" of EI 800 in a standard developer yields very good results, while further pushing to EI 1600 requires more sophisticated processing. A popular method for pushing Tri-X film is using highly diluted developers with little or no agitation and extended development times. This method which is referred to as "stand" or "semi-stand" development, can allow the film to be pushed to speeds up to EI 3200 or 6400.

In 2004 Kodak celebrated 50 years of Tri-X's introduction on November 1, 1954[4] in 35 and 120 formats.

Tri-X panchromatic film was once one of the most popular films used by photojournalists and many amateurs. It was manufactured by Eastman Kodak in the US, Kodak Canada, and Kodak Ltd in the UK. Kodak data-sheets once recommended different processing times depending on where the film was manufactured. Its sales declined in the 1970s and 1980s due to the falling price and increasing popularity of color film. Since the advent of digital photography, Tri-X has all but fallen out of use in newspaper journalism, though it remains popular in documentary journalism.

Tri-X has undergone a number of minor engineering changes during its long history. An early change in ASA (ISO) speed from 200 to 400, around 1960, was due to a change in the ASA standard rather than the film. In 2007, Tri-X was extensively re-engineered, receiving the new designation 400TX in place of TX or TX400, and became finer-grained.

Tri-X also exists as a reversal film for the 16 mm and Super-8 cine film formats. The speed for tungsten lighting (3200 K) is ISO 160 and for daylight ISO 200 when processed as reversal. It can also be processed as a negative at a small loss of speed while the grain will be slightly increased.
