About Schneider Graduated ND Filter
The Graduated Neutral Density Filter is used for Cinematography. 50% of the filter is clear and 50% has a Neutral Density of 0.6 (2 stops). The transition from clear to ND is done with a Soft Edge (SE) transition line. Soft Edge grads lines are used with wide angle and normal focal length lenses. Graduated Neutral Density filters are used to balance exposure within a scene. One very common use is to balance the exposure of sky and earth in a landscape, avoiding overexposed blank white skies.
Schneider Graduated ND Filter Features
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 Graduated Color filter 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 filter is ground and polished to a precise flatness and plane parallelism
It is 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
