Benefits
Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes
Although originally intended for use with black and white film, this filter can also be used as a creative tool in color imaging
Formatt filters use the finest materials together with state of the art production techniques; This has resulted in a standard of optical perfection unmatched anywhere else
All Formatt filters are manufactured using Schott-Desag B270 Crown Optical Glass that is precision polished and ground to ensure absolute optical flatness and optimum performance
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
