68-041844 Neutral Density (ND) 1.8 Filter (4 x 4")

The Schneider Neutral Density (ND) 1.8 Filter (4 x 4") has several uses and offers the possibility to achieve otherwise unachievable results. They enable the shooter to adjust exposure without affecting color balance. ND filters appear gray and reduce the amount of light reaching the film. 

Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters.

Note! Neutral Density Filters are available in grades 1,2,3 and 4 stops to suit individual needs

Neutral Density Filters Have Four Main Uses

To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars

To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background

To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations

To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

High-Quality Construction

Schneider filters feature crystal clear, water-white optical glass, protected against edge-chipping and delamination by Schneider's unique Edge Seal, which also significantly reduces edge reflections and flare

Schneider Quality Control

Schneider filters are ground and polished to a precise flatness and plane parallelism

Because all Schneider filters are designed and manufactured with the highest possible degree of consistency, you can swap like filters mid-shoot with no discernible variation in color or effect

Neutral Density Factors

ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)

ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)

ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

ND 1.2 (exposure adjustment = 4 stops, reduces ISO 1/16)
