The Tiffen 3x4" Fog 1/4 Filter for Photographysimulates 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 greater amount of fog effect than the 1/8, but less than the 1/2, 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 and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 3 x 4" / 76.2 x 101.6mm.

Q: 4. Hi, I'm a little confused about how Rosco is using the term fog and haze. Is the mini-v fog machine appropriate for filmmakers looking to fill a room with haze for shooting videos? Thank you

A: This Rosco Mini-V would be strictly for adding fog to a scene which would have more density than using a haze machine, which produces a thinner vapor. For your application, you may wish to consider the Elation Professional MAGMA PRIME 700W Water-Based Haze Machine, BH # ELMAGMAPRIME. http://bit.ly/3EdQa6W
