Tri-X is a classic high-speed black and white photographic film from Kodak. Introduced in 1954 rated at ASA daylight 200 and tungsten 160, it was the first high-speed black and white film. 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, coming in 24 and 36 exposure rolls of 35 mm and 120 as well as 50 and 100ft bulk rolls of 35mm. Tri-X 320 is available in 120 and 220, as well as 4×5", 5×7", and 8×10" sheets.

Tri-X 400 is rated at ISO 400 when processed in standard developers and remains among the fastest black and white films today. Push processing Tri-X to EI 800 in a standard developer brings very good results, while further pushing to EI 1600 requires more sophisticated processing. Introduced November 1, 1954 [cite web

Since the advent of digital photography it has all but fallen out of use in newspaper journalism. Apart from possible use in educational establishments, it still remains reasonably popular in documentary journalism.
