Cokin Blue (82B) L (Z) Filter

Blue Conversion filters help correct light deemed too warm or amber for the situation. The 82B filter is a pale blue filter that corrects 2900K light to 3200K. This is helpful when you need just a little tweak to the color temperature and not a full conversion from tungsten to daylight. 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.
