Tiffen. 85/ND Combo Filters. 72mm.

Tiffen Filters. 85/ND Combo Filters. 72mm.  is one of several filter combinations so often requested they are produced as two filter effects in one.

Combines an 85 filter (for shooting tungsten corrected film outdoors) with a Neutral Density filter (provides balanced exposures and depth-of-field control).

The ND filtration provides exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (tungsten) films.
