Kodak Tri-X is arguably the most popular b&w film of all time.
Introduced in 1940, first as a sheet film, and then expanding its
formats, in 1954, to the much more popular 35mm and 120 - Tri-X has been
in use for decades and has helped make some of the most noteworthy
photographic images in history. The film is an ISO 400 panchromatic
black and white film that truly defined what b&w films look like.
It has a classic cubic grain structure that gives its images a lot of
character. It also has moderate contrast and deep shadows. It is a
very versatile film and can be pushed easily as high as ISO 12,800.
Meanwhile, entire volumes of data have been published regarding how to
handle the film in the darkroom. Kodak Tri-X is often the film we point
to when a customer asks us where to get started in the world of b&w
photography. While there are many great films to choose from, it's
hard to go wrong with a roll of Tri-X.
