The Tiffen 86mm Coarse Thread Double Fog 1/2 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 1/2 density provides a small amount of fog effect and requires no exposure compensation.
Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
- Provides a fog-like effect with dramatically lowered overall contrast.
- Maintains greater sharpness and is less affected by highlight-flare than the standard Fog filter.
- 1/2 density gives a small fog effect.
- Does not require exposure compensation to make up for filter effect.
