The 81 Color Conversion Filter from Tiffen controls the bluish coloration that affects daylight film. It can also remove excessive blue from the effects of electronic flash. It's Autumn. The clouds are low hanging and the sky is "patchy blue". You've gone for a ride upstate to the mountains and the light in open shade is bluish. A photo taken with daylight balanced film of your girlfriend leaning against the side of a barn will yield bluish tones that she might not find particularly flattering. An 81 filter will replace a drop of the yellow missing from the image and bring her skin tone back to a more appealing level. This filter can be used by the pro and amateur alike, weekend photo warrior or pro cinematographer and must be considered an essential addition to any photo arsenal.
