Tiffen 6.6x6.6" Water White Glass ND0.3 1-Stop Filter camera accessory

Professional exposure control

The Tiffen 6.6x6.6" Water White Glass ND0.3 filter provides a precise 1-stop light reduction for photographers and cinematographers who need to maintain wide apertures or slow shutter speeds in bright conditions. Its water white glass construction prevents color shifts, preserving true-to-life hues across the frame. The square format fits professional matte boxes for studio and location work.

Consistent density under continuous use

The ColorCore lamination process embeds the neutral density material between optical glass layers, so the .3 density remains uniform during long takes or extended shooting sessions. Unlike surface-coated alternatives, the filter resists density drift from heat or handling, delivering reliable exposure control from the first frame to the last. The durable glass withstands rigorous daily use in demanding environments.

Verify matte box compatibility

Confirm that your matte box or filter holder accepts 6.6x6.6" square filters before ordering. The filter has no threads, so it cannot mount directly to a lens barrel. Ensure your workflow supports a 1-stop reduction without requiring additional density steps not provided by this single filter.
