Product Highlights
- Balances Tungsten Under Daylight
- Schott Glass
The Formatt 4.5" 85B Color Conversion 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. 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.
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
- Filter Quality
- Formatt filters are made from Schott-Desag B270 Crown Optical Glass - a high-quality glass that assures you of color consistency from filter to filter
- A #85 filter will produce slightly cooler results than an 85B
