Tiffen 4x5.65" ND 0.9 Filter

Ideal for use with the Arri of Redrock Matte Box.

The Tiffen 4 x 5.65" Water White Glass 0.9 ND Filter is a solid neutral density filter providing a 3 stop exposure. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image.
