With the thin-film technology developed here not only the pure ND filter effect comes into play but a coating combination optimizes the ND filter. In addition to the filter effect the coating combination contains a multi-layer anti-reflective component with 7 layers per filter side to prevent annoying reflections. An outer layer with the usual dirt- and water-repellent properties is applied as the final layer. This not only provides all-around protection for the filter but also makes it easy to clean and maintain the filter pane. The light attenuation itself is very uniform over the entire visible range and produces optimally color-neutral image results. 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.
- Reducing the amount of light entering the camera
- Suitable for both analog and digital cameras
- Selective sharpness by achieving larger apertures ideal for portraiture
- Long exposures producing a cotton candy effect on moving water and deserted streets void of people and cars
- Wipe effects continuous light trails
