The Tiffen 105mm Coarse Thread Fog 1/4 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. There can also be a softening effect due to how the light interacts with the subject matter. The 1/4 density provides a very 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 glowing highlights and lowered overall contrast.
1/4 density gives a very small fog effect.
Does not require exposure compensation to make up for filter effect.
