6.6 x 6.6" Double Fog Filter Density:1 Potential near-infrared or infrared color

Potential near-infrared or infrared color shifts are prevented or minimized

The 1 density provides less contrast adjustment than the 2 density

The bag has YKK double-pull zippers

The warming effect of this filter can be obtained under daylight when this filter is used on a film camera system with daylight film installed

Diffraction spikes are arranged in a pattern where seven primary diffraction spikes are grouped along both sides of the elliptically-shaped light source that are furthest from each other

6.6 x 6.6" Double Fog Filter Density:1 Potential near-infrared or infrared colorThe Tiffen 2 x 3" Double Fog 3 Filter simulates the effects of natural fog or mist by creating a soft glow around highlights and lowering the overall contrast of the scene. When compared to the standard Fog filter, this filter places greater emphasis on lowering the contrast while maintaining sharpness and minimizing the effects of flare. The 3 density provides more fog effect that the 2, but less than the 4, and requires no exposure compensation.
