ND Filters
B+W ND (neutral density) filters, reduce the whole visible light spectrum in a uniform manner and thus lead to a reduction in light intensity without affecting color and contrast. Consequently, running water will be rendered hazy and soft or people walking on streets become blurred or even invisible.

101 ND 0.3
The lightest B+W ND filter attenuates the light by one f-stop. This may be necessary, for example, to correctly expose high-sensitivity films when the brightness of the subject is still too great even after using the fastest shutter speed and smallest aperture allowable. It is ideal as a fine tuning ND filter.

102 ND 0.6
This B+W ND filter, which reduces the light by two f-stops, already shows a clear effect on your photographs such as requiring f/4 instead of f/8 for selective focus or 1/15 sec instead of 1/60 sec for a long exposure effect.

103 ND 0.9
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.

106 ND 1.8
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.

110 ND 3.0
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.

ND Vario
Thanks to its variable density, the first B+W Vario ND filter can be adjusted exactly to meet individual requirements. To this end, it comes with a continuous setting function with which the photographer can determine the required density reduction between +1 and +5 f-stops. Sometimes large apertures are needed in bright ambient light in order to separate a model optically from the background. Using several minutes of exposure time, architectural photographers can make people passing through the work space “invisible”.

ND Graduated Filters
B+W graduated neutral density filters are often used in landscape photography in order to avoid an overexposure of the sky with a correct exposure of the ground. The filters are colored neutral gray on one half with a smooth transition into the neutral clear filter half. With threaded filters the rotatable mount allows an exact horizontal alignment. A B+W graduated ND filter is mainly used to compensate for a sky that is too bright compared to the dark foreground.
