B+W 39mm 81A Warming Color Conversion Glass Filter
This B&W 39mm 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 39mm 81A Warming Color Conversion Glass Filter:
Quality filter for your Leica M system lenses.
Great when shooting colour print but especially good when shooting slide film to give your images just that little extra bit of pop.
Only thing that keeps me from giving this 5 stars is the multi-coated 81A does a slightly better job of reducing lens flare.
