Tiffen 4.5 85N9 Filter

Description

Several filter combinations are so popular that they are produced as two filter effects in one. These include: Neutral Density or Polarizer plus 81 or 85 Wratten.

The 85 warming filtration covers the entire filter area converting the color temperature to 3400K for use with type A (tungsten) films, while the ND Neutral Density 0.9 filtration allows for a exposure reduction of three stops, darkening the entire image so you can choose to photograph with a wider aperture or slower shutter speed than normally required.
