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 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.
