The Tiffen Company has added two new diffusion effects filters to its renowned line of optical filters. Paired with digital cameras, Black Fog and Night Fog Filters can provide a soft highlight glow reminiscent of the classic double fog cinematic look. While both Black Fog and Night Fog series offer the benefits of Tiffen's natural-looking diffusion, these two new atmosphere-enhancers each bring a unique benefit to the cinematographer's pallet.
   

Tiffen Black Fog filters provide an overall atmospheric softening that creates a smooth wide flare from the highlights yet keeps the blacks, black without overly muting colors or losing detail in shadows. This more subtle effect can be used to add an overall look to a project.

Night Fog filters yield a natural fog effect with overall atmospheric softening and wide flare, coupled with unique contrast reduction technology that reduces highlights without darkening shadows. In light grades, it provides a beautiful new look. In strong grades it flattens the contrast and desaturates color so it is useful for day-for-night.

The new Fogs have been used in real production conditions by cinematographers around the globe. Steven Poster ASC, who is gearing up for his next film, said: "I think they both have similar qualities to the Classic Double Fog when they are used with digital cameras. They can create a sticky dark day, a romantic softness emphasizing the highlights, or an atmospheric nighttime motif."

Like the rest of Tiffen’s Emmy & Academy Award-winning filters, Black Fog and Night Fog filters are crafted in the USA with Water White glass. To promote long life, only Tiffen filters are manufactured using the exclusive Colorcore Technology process that laminates the filter substrate between two pieces of optical glass, then grinds and polishes them to a precise tolerance of 1/10,000th of an inch flatness.

Each filter type comes in standard sizes (4x4, 6.6x6.6, 4x5.65, 138mm) with a choice of 1/8, ¼, ½, 1, or 2, densities. Special sizes and strengths are available upon request.
