B+W Filter ND 810 86 mm Master MRC Nano. ND filters or neutral density (ND) filters are used if too much light restricts creative possibilities. With a light reduction of ten f-stops, this ND filter delivers a further intensification compared with the B+W ND 106. Running water virtually transforms into mist. People walking on streets become blurred and indistinct or even invisible. In some cases this involves extremely long exposures of up to one minute. A stable tripod is essential.
ND filters can produce wipe effects in movements if the exposure time can be extended with the required aperture. A waterfall then no longer appears to be frozen, but as a flowing motion. ND filters create ingenious effects in architecture or urban photography. With long exposure times of several hours, people walking through the shot are blurred or not reproduced at all. For physical reasons, very dense filters possess a warm tone which can be compensated in image processing.
Available with different densities
B + W ND Filters are available with several different densities, which gives the photographer the opportunity to choose a filter that suits each situation.
MRC Nano Coating
An important criteria for a perfect B+W filter is a high-quality coating, also known as an antireflection coating. With a B+W filter, such layers are evaporated by means of thin-layer technique, a quite complex coating process. The coating material consists of special substrates that are applied in one or more layers depending on the coating system.. In the MRC nano coated B+W filter, a water droplet remains practically spherical. It rolls over the surface. A first-rate dirt and water-repellent effect occurs.
Master Filter Holder
Durable and robust due to brass mount with better grip due to optimized knurl. Easier mounting due to new lacquer technology. Best choice for super wide angle – telephoto lenses.

In addition to the filter effect, the combination coating also prevents trouble-some reflections by including a multilayer anti-reflection compo-nent with seven layers on each side of the filter. Finally, an outer layer with the usual dirt- and water-repellent properties is applied. With this feature, the filter not only has all-round protection, but simple cleaning and care of the filter disk are also taken care of. The light attenuation itself is very uniform over the entire visible range and therefore produces optimal, colour-neutral images.
