The Series 9 Fog 4 Filter from Formatt is an excellent filter to use when you want to recreate the effect of standing in a natural fog. It generates a soft glow and flare producing a warm romantic tone. A natural fog causes lights to glow and flare. A Fog filter lowers contrast and sharpness may be affected as well.
If you think of a perfume atomizer, that is what a Fog filter will resemble. Like tiny droplets in the air, a Fog filter creates a soft, diffused image that is useful when you need to recreate the effect of humidity in a tropical scene.
A #4 Fog filter is a step up from the grade 3. The #4 has a very strong effect with the image often taking on a fantasy or dreamlike appearance. An significant glow will surround your highlights with flare becoming much more noticeable. Contrast and sharpness will continue to be lowered.

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
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 color cast caused by conventional greenish soda-lime glass
Formatt, a company with three generations of professional filter-making experience produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology have resulted in a standard of optical excellence unmatched anywhere else
