Square Filters 800 Series

More creativity for landscape photography

High-quality finely ground and polished special glass forms the basis of the ND square filters. This guarantees the necessary optical quality and ensures that a high quality lens is not compromised.

The ND filter effect is created by coating the glass surface. Uniformity is important because only then is light evenly attenuated over the entire visible area, resulting in optimum colour-neutral images. Using this manufacturing technology, a combination of coatings ensures the highest quality filter lenses and, in addition to the filter effect, reduces unwanted reflections via an anti-reflex system (7 layers per filter side).

Finally, a water-and-dirt-repellent nano coating is applied. This scratch-resistant coating protects the whole of the square filter. It also facilitates easy cleaning and maintenance of the filter. 
 

tip


  • Flow effects can be created with a shutter speed of
    ¼ second and above.
  • The longer the exposure time, the stronger the effect
    (ND 806/810/815)
  • Experiment with different exposure times
  • Use the manual exposure setting
  • Use low ISO sensitivities and small aperture values
  • A stable tripod is essential

Information


The effect of two ND filters results from the sum of the density values. For example, the B+W ND filters 802 (ND 0.6; +2 f-stops) and 803 (ND 0.9; +3 f-stops) combined creates a density of ND 1.5 and thus comply with the effect of +5 f-stops.

TECHNICAL SPECIFICATIONS


The innovative ND coating technology delivers considerably higher colour fidelity when compared to melted ND filters. The coating material can almost completely balance the physically induced excess of red component. Thanks to the optimised colour reproduction across the visible light spectrum, subsequent image processing is made easier and less time consuming for the photographer.
