Professional Tri-X 400 Black and White Negative 35mm Film, 35mm Film - 24 Exposures

Kodak Tri-X 400 Black & White Film (24 exp) — the iconic street-and-travel B&W stock, in a shorter roll

The gist: A 24-exposure roll of the classic Kodak Tri-X 400, the black-and-white film that's defined documentary and street photography since 1954 — a shorter roll length that's easy to finish and swap out during a fast-moving travel day.

• Wide exposure latitude: forgiving enough to handle mixed lighting on a travel day — bright plazas, shaded alleys, dim transit — without ruining a shot.
• Pushes up to 3 stops: shoot it at higher ISOs for low-light bars, night markets, or evening streets, then push in development for a punchier, grittier look.
• Shorter roll, faster turnover: at 24 frames instead of 36, it's easier to finish a roll in a single city or day trip, useful if you like developing film in batches by location.
• Bold, classic contrast: delivers the deep blacks and expressive tonality Tri-X is known for, distinct from the finer-grain look of modern T-grain films.

The Darkroom's film review calls Tri-X "one of the most iconic film stocks ever made," noting it "pushes incredibly well, pulls incredibly well" and offers "excellent exposure latitude" that makes it forgiving across a wide range of shooting conditions.

Best for: travelers who want the classic, gritty Tri-X look and prefer finishing a roll per location or day. Skip it if: you'd rather shoot a full trip on one roll — the 36-exposure version stretches further. Runs ~$5 — check the current price before buying.
