Very well drawn clouds and a strong instead of milky tone in the sky can be achieved with this already stronger graduated filter. It attenuates at its darkest zone by two f-stops. This makes it possible to create landscape motifs with very high contrast without loss of detail.
The gradient zone leaves some play, but for a natural transition the horizon line should not be too far off center. 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. The high-quality glass substrate of the B+W ND filters 702 is absolutely plano-parallel and finely polished. This guarantees for long lasting high optical quality versus easily scratchable plastic substrates.
A B+W graduated ND filter is mainly used to compensate for a sky that is too bright compared to the dark foreground. For exposure metering, the camera or hand-held exposure meter should be pointed down towards the ground that is to have the correct exposure without the graduated filter. This almost always produces the ideal effect automatically.
