This is a Set of 3 Fog filters (Strength 1,2 and 3) in the size of 4×4. This size is especially popular with ambitious S16 filmmakers. Although the filters are used, they are in good condition.

The Tiffen Fog 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 density provides a subtle 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.
