Tiffen 77mm Double Fog 1/2 Filter

The Tiffen 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 less fog effect that the 1 but more than 1/4. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. 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. Does not require exposure compensation to make up for filter effect. Creates a soft glow and flare Produces a warm romantic tone Lighter grades take the edge off excess contrast and sharpness Heavier grades create unnatural effects, as in a fantasy sequence or a dreamlike aura of mystery Double Fog Filter Produces a more natural heavy fog effect where objects remain sharper and contrast is substantially reduced Tiffen Optical Filters Tiffen filters are manufactured using ColorCore™ technology, a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision metal rings. The ColorCore process allows us to control the color and density of Tiffen filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations.
