Tiffen 6.6x6.6" Water White Glass ND2.1 7-Stop Filter camera accessory

Professional Neutral Density Filter

The Tiffen 6.6x6.6" Water White Glass ND2.1 filter delivers 7-stop light reduction for professional photographers and cinematographers who need precise exposure control in bright conditions. Its ColorCore construction laminates the filter material between optical glass pieces ground flat to a 1/10,000th inch tolerance. This design maintains true-to-life colors without shifts while enabling wider apertures or slower shutter speeds for creative depth-of-field and motion effects.

Filter Holder Compatibility Check

Verify that your matte box or filter holder accepts 6.6x6.6 inch (167.6 x 167.6mm) square filters before ordering. The filter's solid glass construction requires a secure, flat mounting surface to prevent light leaks or vignetting. Ensure your existing filter trays or frames are clean and free of debris that could stress the glass during installation or affect optical performance.

Creative Exposure Control Integration

This neutral density filter fits into professional matte boxes and filter holders as a primary exposure management tool, freeing you to select wider apertures for shallow depth of field or slower shutter speeds for motion blur in bright light. The Water White glass and ColorCore process preserve color fidelity when stacking with other filters such as polarizers or graduated NDs. Its scratch-resistant durability supports reliable daily use on demanding production sets.
