B+W 46mm 81A Warming Color Conversion Glass Filter
This B&W 46mm 81A Warming Conversion Glass Filter has an effect similar to that of the Kodak Wratten 81A gelatin filter. It is also similar to the KR1.5 (Skylight) conversion filter except that it is less reddish as it absorbs a little bit of the red.
The 81A controls the bluish coloration that affects daylight film. It can also remove excessive blue from the effects of electronic flash. Good for general scenics when the photographer wishes to remove the bluish cast from open shade or just add warmth to the photograph.
Note! Whereas the KR series (and the 81 series) of filters creates a feeling of warmth, the KB Series (and the 82 Series) creates a feeling of coolness
- It can be used like the KR1.5 (Skylight) filter especially with films that tend to a reddish rendition inherent to their emulsion or to the developing process
- Ideal for landscape photographs at noontime and for flash exposures on daylight reversal film when the light emitted by a compact flash unit has too high a color temperature (and, this, an excessive blue component)

Comments about B+W 46mm 81A Warming Color Conversion Glass Filter:
this filter is simply great. I've used extensively on my canon gear, and it gives a great warm look that isn't hardly noticed.
It also protects the lens. The construction is great like all b+w products. Solid and light.

Comments about B+W 46mm 81A Warming Color Conversion Glass Filter:
i use this filter for 35mm film. The 81 A filter turns flat white into a warm off white, boosts the yellow in greens, and seems to diminish the blue of the sky. It was recommended to me by a friend who is a very well known fashion and fine art photographer.
