Kodak Tri-X 400 is the classic documentary black-and-white film, and its look is punchy and gritty: deep blacks, bright highlights, and contrast with an edge. Luttie's Grit 400 is shaped after it, mixed from colour the way a panchromatic film sees.

Since 1954 Tri-X has been the film of photojournalism and street photography, shot by generations of photographers covering wars, music and city life. Its contrast and grain became the look of serious black and white, which is why so many black-and-white presets are, underneath, trying to be Tri-X.

Soft, gentle portraits: Tri-X is contrasty and unforgiving of flat light. Mono 400 (shaped after HP5) is softer.
Tri-X is punchier, with deeper blacks and a grittier feel; HP5 is softer and more forgiving. In Luttie, compare Grit 400 and Mono 400 on the same photo.
You can put the Tri-X look on your own photos and footage free in Luttie's browser editor, and download the graded image. Exporting it as a .cube LUT is part of Luttie Pro.
No. Grit 400 follows the general shape of Kodak's published Tri-X curves, with its contrast and spectral mix chosen by eye. It hasn't been measured against real film, and Luttie isn't affiliated with Kodak.
Drop in a photo or pull a frame from a video, grade it in the browser, and export a .cube LUT for DaVinci Resolve, Premiere Pro, Final Cut Pro or CapCut.
