The Cokin Z-PRO 026 (81A) Filter 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 of your girlfriend leaning against the side of a barn with daylight balanced film will yield bluish tones that she might not find particularly flattering.
An 81A filter will replace some of the yellow missing from the image and bring her skin tones back to a more appealing level. The 81 series (81A, B, C, D and EF) allows you to choose how much warmth you wish to replace in the image.
The Z-PRO Series is recommended for focal lengths of 20mm onwards (in the 35mm format). This filter is made of CR39 Resin which is a reputable lightweight and unbreakable optical material also used for ophthalmic glasses.
Note! Whereas the 81 Series of filters creates a feeling of warmth, the 82 Series creates a feeling of coolness
