FORMATT 85C 4X5.65 (WHITE BALANCE)

The Formatt 85B 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. 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





85 Series Conversion Chart



- An 85 decreases the color temperature from 5500-3400K

- An 85A decreases the color temperature from 5500-3100K

- An 85B decreases the color temperature from 5500-3200K

- An 85C decreases the color temperature from 5500-3800K





Absorbing Cell Technology



- The secret to Formatt's consistency in filter design lies in its unique "Absorbing Cell Technology" (A.C.T.); This unique process allows color correct dyes to be applied to optically pure, wafer thin absorbing cells and offers a controllability that ensures the smoothest grad lines and consistent color across the whole filter surface.



- This process is revolutionary compared with conventional filter dying techniques by eliminating the need to directly coat the glass surface itself. The repeatable performance gained through A.C.T. ensures that at any time you have to swap like filters for like filters mid shoot, you can do so with confidence with no discernable differences in color or density.



- Each filter is guaranteed flatness to a maximum 2-wave value and comes with an individual reading from a laser interferometer. Every filter is carefully verified with a densitometer and spectrophotometer to ensure consistent and accurate transmission, before leaving the factory - the result is an absolute purity of image that eliminates any unwanted colorcast caused by conventional greenish soda-lime glass.
