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