Amber Conversion filters help convert cool or blue light to warmer light. The 81C filter is a pale amber filter that corrects 5500K light to 5100K. 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.
