B+W 77mm Neutral Density 1.8 MRC Nano Master

77mm Neutral Density 1.8 MRC Nano Master

This B+W ND filter, which reduces light entering the camera by six f-stops, already qualifies as an extreme filter. With this filter, and without changing the aperture (and DOF), an exposure time of 1/60 s becomes a full second. Running water is rendered hazy and soft. A tripod is necessary in any case.
