When to Use Kodak Tri-X 400 vs. Ilford HP5

Tri-X 400 and Ilford HP5 Plus 400 are both classic B&W ISO 400 films, but they offer very different looks and handling characteristics.

Kodak Tri-X 400

  • Look: More contrast, more prominent grain, deeper blacks
  • Best For: Gritty street work, expressive portraits, dramatic lighting
  • Push Capability: Easily pushed to ISO 800, 1600, or 3200
  • Style: Punchy, bold, emotional

HP5 Plus 400

  • Look: Lower contrast, smoother tonal transitions, softer grain
  • Best For: Fine art work, nuanced portraits, tonal depth
  • Push Capability: Excellent up to ISO 1600 with mild contrast increase
  • Style: Subtle, flexible, forgiving

Use Tri-X when you want attitude and visual grit. Use HP5 when you want range, flexibility, and tonal subtlety.

Practical Tips for Shooting & Processing

Exposure Tips

  • Rated at box speed (ISO 400) for classic results. I like it at EI 250 because this is the real speed of this film and this EI rating produces denser negatives.
  • Can be rated at ISO 800, 1600, or even 3200 and still deliver excellent images.
  • Overexpose slightly (e.g., rate at ISO 250) for slightly smoother grain and improved shadow detail.
  • Tri-X thrives in dramatic lighting—look for directional light and shadow.

Development Tips

Tri-X works beautifully in a variety of developers. Here’s a quick reference:

Tip: Agitation frequency and dilution have a big impact on contrast and grain with Tri-X. Experiment with semi-stand or minimal agitation methods for a softer look.
