The Tiffen 4 x 4" Double Fog 3 filter simulates the effects of natural fog or mist by creating a soft glow around highlights and reducing the overall contrast of the scene. Compared to the standard Fog filter, this filter places greater emphasis on reducing contrast whilst maintaining sharpness and minimising the effects of lens flare. The density 3 produces more fog effect than the 2, but less than the 4, and requires no exposure compensation.

Tiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6 mm.


Features:

- Produces a fog effect with a dramatic reduction in overall contrast.
- Maintains better sharpness and is less affected by highlight reflections than the standard Fog filter.
- Requires no exposure compensation to account for the filter's effect.
