Tiffen 6.6x6.6" Water White Glass ND 1.8 6-Stop camera accessory

Professional 6.6x6.6" Neutral Density Filter

This Tiffen filter is a solid neutral density accessory crafted from Water White glass using ColorCore technology. It provides a 1.8 density rating that delivers a precise 6-stop reduction in light entering the lens. The construction laminates the filter substrate between two pieces of optical glass ground flat to a tolerance of 1/10,000th of an inch. It measures 6.6 x 6.6 inches (167.6 x 167.6mm) for use in professional filter systems.

For cinematographers needing exposure control

This filter suits professionals who require true-to-life colour rendition while shooting at wider apertures or slower shutter speeds in bright conditions. It enables creative motion blur and depth-of-field manipulation without affecting image colouration. It is not intended for photographers using standard circular screw-in filter threads or smaller matte box systems. Users needing variable density adjustment or graduated neutral density effects should look at alternative filter types.

6-stop light reduction via 1.8 density Water White

The single specification that determines suitability is the 1.8 neutral density rating, which blocks exactly six stops of light across the full 6.6x6.6" surface. This fixed density allows consistent exposure control for cinema lenses and large-format systems. The Water White glass substrate prevents the colour casts common in standard optical glass. Verify that your matte box or filter holder accommodates the 167.6mm square dimensions before purchase.
