The Heliopan Bay 104 KR15 (85B) Glass Filter will produce natural colors when shooting with tungsten film outdoors. Using tungsten film in daylight will produce a bluish cast in the photograph.

What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.

An 85B filter converts tungsten film to daylight. An 85C produces the coolest results - more than either the 85 or 85B. However, it is interesting to remember that an 85C is also useful as a creative warming filter with daylight film in daylight.

Heliopan Lichtfilter-Technik of Munich, Germany, has changed their black anodized brass filter rings on most Heliopan non-rotating filters to their "slim" mounts. These slim mounts are made of black anodized brass stock and have so little rim in front of the lens (5.4mm) that they will not vignette with lenses as short as 21mm.

Heliopan offers a wide selection of sizes, screw-in, series, bayonet, square and rectangular filters including digital, video, center weighted, graduated, wide angle, Kaesmann polarizers, drop-in polarizers, etc.

Note: Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting. This filter is specific to lenses with Hasselblad's exclusive Series 104 (Bay 104) filter size

Although the KR15 is used for the same photographic situation as the KR12, this dark brown filter is the better choice when photographing areas with very clear air or high daylight temperature (midday summer sun
A #85 filter will produce slightly cooler results than an 85B
Heliopan cuts, grinds, polishes and coats their filters with the same techniques and equipment as used for the finest German camera lenses
All Heliopan screw-in type and series size filters are mounted in precision black anodized brass rings to eliminate binding or cross threading and to ensure optimal alignment
Filters still retain front threads for a lens cap, a lens hood or even stacking a second filter
The portion of the Heliopan slim filters that are in front of the lens have been reduced in thickness by 37% over the former mount
Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting
