Kodak Tri-X 400 and Ilford HP5 Plus are the two best-known 400-speed black and white films, and they are close cousins in how they are used. Tri-X leans toward bold contrast and a pronounced grain look, while HP5 Plus leans toward a softer, more flexible tonal range. Choose Tri-X for punch, and HP5 Plus for latitude and gentle contrast.
What Each Film Is For
Tri-X 400 has long been a favorite for street photography and reportage. Its look is direct: strong blacks, crisp midtone separation and grain that is part of the character.
HP5 Plus is a general-purpose film that many photographers use when lighting is unpredictable. It tends to produce a smoother, more neutral tonal scale that is easy to adjust in the darkroom or in editing software.
Key Differences
| Trait | Tri-X 400 | HP5 Plus |
|---|---|---|
| Contrast | Bold, punchy | Softer, flexible |
| Grain | Classic and visible | Moderate, a little smoother |
| Exposure latitude | Forgiving | Very forgiving |
| Pushing | Long tradition | Long tradition |
| Look in scans | Strong, graphic | Neutral, easy to edit |
These are general impressions. Check each maker’s data sheet for exact specs and development times.
How to Choose
- Choose Tri-X 400 if you want a graphic, high-contrast result with little editing.
- Choose HP5 Plus if you prefer a neutral negative that you can shape later.
- Choose HP5 Plus for scenes with a wide range from bright sky to deep shade.
- Choose Tri-X 400 for gritty street scenes and dramatic window light.
A Simple Way to Compare Them
- Load one roll of each into two bodies, or finish one roll before loading the next.
- Shoot the same scenes: a portrait in window light, a street corner, and a high-contrast outdoor view.
- Expose both at their nominal speed of 400 for the first round.
- Develop both in the same developer with the same agitation routine.
- Scan or print with identical settings and compare shadows, highlights and grain side by side.
Change only one variable at a time. If you also change developer, you will not know what caused the difference.
Also think about your finishing method. Darkroom printers often like the smooth midtones of HP5 Plus, while scanning workflows can make either film look excellent with a few small adjustments. A single test roll of each in your own camera will tell you more than any chart.
FAQ
Can I push both films to 1600?
Both are widely pushed by photographers who shoot in dim light, and both respond with more contrast and grain. Follow the maker’s guidance for development changes.
Do they work in the same developers?
Yes, both work in common black and white developers. Times differ by film and developer, so check a current development chart before you mix chemistry.
The Short Version
Tri-X 400 gives a bolder, grittier image, and HP5 Plus gives a flexible, softer one. If you cannot decide, shoot a roll of each in your usual light and keep the one whose negatives you enjoy printing.
