Kodak Tri-X 35mm Black & White Film Tribute 15oz Black MugKodak Tri X is one of the most iconic black and white films ever made, known for its speed, flexibility, and unmistakable look. Introduced in the 1950s, it became the film of choice for generations of photographers thanks to its high ISO rating (originally 200, later 400) and its ability to be pushed in development for even higher sensitivity. Its forgiving exposure latitude and consistent results made it equally useful for professionals and students.
