This 4-stop, 5 x 5" Water White Glass Combination 85/ND Filter from Tiffen consists of a neutral density 1.2 and a Wratten 85 filter. This filter reduces the amount of light passing through the camera lens without changing the color of the scene. It is especially useful in bright light conditions to help prevent overexposure. Neutral density filters also allow proper exposure at a wider lens opening for reduced depth of field to highlight a key subject by making the foreground and/or background out of focus.
