Schneider Optics 6.6 x 6.6 Neutral Density (ND) 0.3-1.2 Attenuator Filters

Schneider Optics 6.6 x 6.6 Neutral Density Attenuator Filters 0.3-1.2

This is a special type of Neutral Density Filter. Neutral Denisty Attenuators diminish distracting backgrounds by enabling the use of wider lens apertures, thereby reducing depth of field. Conversely, these ND Attenuators can be used to properly expose varying light levles within a given frame. They allow the amount light reaching the film to be controlled without relying solely on camera aperture. Neutral Density Attenuators are made using the finest crystal-clear water-white optical glass and are precision engineered with unparalleled smoothness, uniformity and consistency. They can be used alone or in combination with other filters with no degradation of image quality.

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

Neutral Density: 

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

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

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

ND1.2 (exposure adjustment = 4 stops, reduces ISO by 1/16)
