Cokin Warm (81EF) L (Z) Resin Filter

Amber Conversion filters help convert cool or blue light to warmer light. The 81EF filter is an amber filter that corrects 5500K light to 4900K. This is helpful on overcast days or shady environments where the light tends to be cool and a little warmth is needed. It is a critical tool for film photographers because film has a fixed light balance that should be corrected in-camera for the most accurate results.
