Tiffen 4 x 4" Fog 5 Filter

The Tiffen 4 x 4" Fog 5 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 5 density provides the greatest amount of fog effect and requires no exposure compensation.
