This B+W ND filter reduces the light by three f-stops and is particularly interesting for video when no suitable aperture can be selected in bright light or when a specific, small DOF is required. With this filter, distinct flow of water effect becomes apparent. The B+W 103 ND filter 0.9 is also ideal for shooting photos with a wipe effect.
