Tri-X 400 vs Acros 100: Which Film Stock Should You Choose?

Q: Is Tri-X 400 or Acros 100 better for fine art photography?

Acros 100 is the better choice for fine art photography. Its ultra-fine grain, smooth tonal gradations, and rich detail reproduction make it ideal for gallery prints, long-exposure architecture, and contemplative landscapes. Tri-X 400 has a grittier, more documentary feel that is better suited to street photography and photojournalism.

Q: Can I use Acros 100 for street photography?

You can, but it is challenging. At ISO 100, you need bright conditions to get fast enough shutter speeds for street work. Acros 100 produces a smoother, more refined look than the gritty aesthetic traditionally associated with street photography. If you shoot street in bright daylight and want a cleaner, more elegant monochrome look, Acros can work beautifully.

Two black-and-white legends from opposite philosophies. Kodak Tri-X 400 is the gritty, high-contrast workhorse of street photography and photojournalism. Fujifilm Acros 100 is the smooth, ultra-fine-grain instrument of fine art and contemplative monochrome. Punch versus precision.

When to Choose Tri-X 400

Tri-X 400 is film that matches the pace of life. It was designed to be loaded and shot without overthinking, in conditions that range from bright sidewalks to dim interiors.

Street photography in any light -- At ISO 400, Tri-X gives you the speed to shoot handheld in shade, late afternoon, and indoor spaces. Its gritty grain adds urgency to fast-moving street scenes.
Documentary and photojournalism -- When the moment matters more than the tonality. Tri-X's forgiving nature and high contrast produce images with immediate visual impact.
Portraits with dramatic character -- Tri-X renders skin with sculptural contrast. The grain adds texture. The result is portraits that feel like they belong in a magazine feature, not a beauty ad.
When the grit is the point -- Sometimes you want the photograph to feel physical, rough, and real. Tri-X's grain is not a flaw -- it is the voice of the image.

When to Choose Acros 100

Acros 100 is the thinking photographer's B&W film. It rewards patience, careful composition, and precise exposure with images of extraordinary smoothness and tonal depth.

Fine art and gallery prints -- Acros 100's virtually invisible grain means prints are smooth and luminous at any size. The tonal gradations are continuous and rich, with shadows that retain detail rather than falling into black.
Architecture and long-exposure work -- Acros has almost zero reciprocity failure, meaning long exposures of 30 seconds to several minutes produce consistent, reliable results. Moving water, cloud streaks, and empty streets rendered in smooth, dreamy B&W.
Contemplative landscapes -- Mountains, forests, still water. Acros renders natural textures -- bark, stone, fog -- with extraordinary detail and smoothness, creating images that invite quiet study.
When smoothness and precision matter -- Acros is the black-and-white equivalent of large-format photography. It is about maximizing tonal information and minimizing the presence of the medium.
