The Hoya 67mm 85B Color Conversion Hoya Multi-Coated (HMC) Glass filter will produce natural colors when shooting with tungsten film outdoors. 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.
