Formatt BF4CC10MAG - HItech Glass 4x4

Formatt 4 x 4" CC 10M Magenta Color Compensating Filter or CC's act as sponges, absorbing excessive amounts of particular colors. Some photographic situations require specific color corrections. For example, when shooting daylight film under fluorescent lighting, some magenta correction is needed in order to remove the greenish tint that would otherwise appear.

Formatt CC filters offer color control of primary (red, green, blue) and secondary (yellow, magenta, and cyan) levels. Densities range from 0.025 to 0.50; by combining different densities, it gives the flexibility to knock out specific colors as well as offering extremely fine adjustments in color temperature.

Note! The amount of color correction required is most accurately measured via a color temperature meter


Benefits

- Color Correction filters are specifically designed to affect the color sensitivity of film emulsions
- A typical designation for one of these filters is CC30M; the "CC" stands for Color Compensating; the "30" stands for a density of 0.30 and the "M" is for magenta
- Formatt manufactures three types of Color Correction Filters - Color Temperature Conversion, Light Balancing and Color Compensating
- Optically consistent from filter to filter
- 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 Water White Schott 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.
