Quick answer

Choose Kodak Tri-X 400 for classic grain and exceptional push-processing; pick Kodak EKTAPAN 400 for ultrafine grain and higher sharpness in standard development.

Grain and sharpness: classic vs modern

Tri-X 400 is known for its classic, visible grain that adds texture and character to images. It is a traditional cubic-grain film, which gives it a distinctive look that many street and documentary photographers love.

EKTAPAN 400 uses a T-grain emulsion with tabular silver halide crystals, resulting in ultrafine grain and increased sharpness with more distinct edges. This makes it a cleaner, more modern-looking film, ideal for subjects where detail and smoothness are priorities.

Push processing: flexibility vs consistency

Tri-X 400 is renowned for its wide exposure latitude and responds well to push processing. You can rate it at ISO 800, 1600, or even 3200 with predictable results, making it a go-to for low-light or high-speed shooting.

EKTAPAN 400 is not marketed for push processing and is best exposed at its box speed of ISO 400 for optimal grain and sharpness. Pushing may introduce contrast and grain, but it is not the film's intended strength.

Trade-offs at a glance

  • Grain character: Tri-X: classic, visible grain adds texture. EKTAPAN: ultrafine, smooth grain for cleaner images. If grain is part of your style, choose Tri-X. For clean scans, choose EKTAPAN.
  • Sharpness: EKTAPAN offers increased sharpness and more distinct edges due to its T-grain emulsion. Tri-X is sharp but with a softer edge. For maximum detail and edge definition, EKTAPAN is the winner.
  • Push processing: Tri-X responds well to push processing up to ISO 3200. EKTAPAN is best at ISO 400 and not optimized for pushing. If you shoot in low light or need high speed, Tri-X is the flexible choice.
