The Tiffen 4.5" Round Fog 1 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 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.

Q: 1. Does this fit in the Nisi 100 filter holder?

A: The Nisi 100 filter holder is designed for 2mm thick filters. Tiffen MPTV filters are 4mm thick which allows the filter "effect" to be laminated in between two pieces of glass. This prevents the "effect" from being scratched and also makes the filter more durable. To hold our 4x4 or 4x5.65 MPTV filters you can use the Tiffen Pro100 filter holder.
