These filters are special versions of the B+W Circular Polarizing Filters combined with a warm tone filter. This combines the optical qualities of both filters in a single filter.
Part Circular Polarizer
Highly efficient standard circular polarizing filter for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings.
B+W Polarizers increase color saturation and reduce reflections. The neutral gray color and plane parallel polarizer material guarantee optimal image results. High-quality optical glass ensures excellent pictorial quality. The filter factor varies according to how the filter is positioned in relation to the sun. Filter factor is between 2.3 and 2.8.
Part Warming Filter
This conversion filter has an effect similar to that of Kodak Wratten 81A gelatine filter. Its strength of 18 Mired makes it approximately similar to the KR 1.5 conversion filter, except that it is less reddish as it absorbs a little bit red. It can be used like the KR 1.5 filter, especially with films that tend to a reddish rendition inherent to their emulsion or to the developing process. The 81A conversion filter is also 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 thus an excessive blue component).
