What Is Push Processing?

Push processing means underexposing film (shooting at a higher ISO than rated) and compensating with extended development time. This increases contrast and grain.

When to Push

  • Low light situations where you need faster shutter speeds
  • When you want more contrast and grain for artistic effect
  • Concert and event photography
  • Classic photojournalism look

Common Push Combinations

Tri-X at 1600 is a classic look. HP5 can be pushed to 3200. Color negative film can usually be pushed 1-2 stops, but color shifts may occur.
