Product description
The latest addition to the B+W XS-Pro filter line up, this Neutral Density filter utilizes the latest in thin film technology, resulting in an improved ND effect for even truer neutrality. This Neutral Density filter reduces the light by six f-stops. With this filter and without changing the f-stop, a shutter speed of 1/60 s is changed to a full second, thus requiring the use of a tripod. Flowing water is rendered as flowing in the photo, and people moving in streets are dissolved in sharpness or become invisible. The filter factor is 64x
