Kodak Tri-X 400 is arguably the most important black and white film stock in photographic history. Introduced in 1954, it became the defining film of photojournalism — used by Henri Cartier-Bresson, W. Eugene Smith, Gordon Parks, and generations of documentary photographers. Its combination of 400 ASA speed, distinctive grain structure, and exceptional exposure latitude made it the professional standard for available-light photography for over 60 years. Tri-X is still manufactured today — a living artifact of an unbroken tradition spanning seven decades.
