KODAK Tri-X 400 35mm Black-and-White Film 36EXP

KODAK Tri‑X 400TX is a versatile, high‑speed 35mm black‑and‑white film built for low light, fast action, and flexible processing.

Trusted by documentary, street and portrait photographers for decades, Tri‑X 400TX combines classic silver‑halide character with modern grain structure and wide exposure latitude. This 36‑exposure roll at ISO 400 balances fine grain and high resolving power so images retain detail when enlarged, while also tolerating push processing to achieve greater effective speed when needed. The film’s panchromatic sensitivity renders tones naturally across the visible spectrum, making it a go‑to choice for photographers who want reliable black‑and‑white results in varied shooting conditions.

How well does Tri‑X 400 perform in low light and fast‑action situations?

Tri‑X 400’s nominal ISO 400 rating gives you a good compromise between speed and image quality, and it responds predictably to push processing for higher effective speeds. That makes it suitable for available‑light street work, evening events, and motion where faster shutter speeds are required.

• ISO 400 base for balanced grain and sensitivity.
• Push‑process friendly — commonly pushed to ISO 800 or 1600 with controlled contrast.
• High resolving power preserves detail in motion shots.
• Panchromatic response captures natural tonal relationships across colors.

What image characteristics can I expect: grain, contrast and sharpness?

Tri‑X 400 yields a classic silver grain texture that is fine for a high‑speed film while maintaining impressive sharpness. Expect medium contrast by default, which keeps highlight and shadow detail usable for printing and scanning.

• Fine, film‑character grain suitable for enlargements and prints.
• Moderate contrast that preserves shadow and highlight information.
• High sharpness and resolving power for good rendition of small details.
• Consistent tonal roll‑off that works well for a variety of subjects.

How should I expose and process Tri‑X 400 for best results?

Expose at ISO 400 for general shooting; consider overexposing by one stop for cleaner tones or underexposing cautiously if you need to retain highlight detail. Darkroom developers and most C‑41 alternatives are not compatible—use standard black‑and‑white chemistry and consult processing times for push/pull adjustments.

• Meter at ISO 400 for neutral results, or push to ISO 800–1600 with adjusted development.
• Use standard B&W developer recipes; refer to manufacturer or processing lab specs for times.
• Handle in subdued light and keep processing consistent for predictable contrast.
• Scan negatives at higher resolution to capture grain and detail for digital workflows.

Why do professionals still choose Tri‑X in a digital era?

Tri‑X 400 delivers a tangible aesthetic and tonal quality that many photographers find difficult to replicate digitally. Its flexibility, pushability and proven archival properties make it a reliable creative tool for projects where black‑and‑white character matters.

• Classic film look valued in editorial, documentary and fine art work.
• Predictable behavior across exposure and development variations.
• Good for both contact prints and enlargements thanks to resolving power.
• Stable, widely supported by labs and scanning workflows.
