B+W SLIM 77mm ES-77 81B Color Conversion Coated Warming Glass Lens Filter Made in Germany
New Old Stock May need Cleaning
The 77mm 81B Filter from B+W controls the bluish coloration that affects daylight film. Even though the human eye automatically adjusts to various lighting conditions, film does not. Irrespective of the light source, a white sheet of paper will always "appear" white to the human eye. However, when photographed under various lighting sources, the paper will reproduce a representation of the light it was shot under. An 81B filter will allow you to correct for this white balancing problem when you wish to reduce the color temperature of the shot and bring your tones back to a more acceptable level.
We do combine S&H charges.
