B+W

ND 700 Series (Graduated)

Balance between heaven and earth

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 701 and 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.

Any increase in exposure to compensate for the absorption in the dense part of the graduated filter should be low so as not to weaken the filter effect too much!

Key Features


  • Adjusting and balancing for variances in brightness
  • Ideal for landscape photography
  • Uniform gradient from edge to center
  • Available in two strengths
  • Suitable for analog as well as digital cameras
  • Made in Germany

Additional information


The gray gradient is applied by means of thin-layer technology. The special coating process requires a special masking. This is associated with certain manufacturing tolerances, with the result that the graduation boundary is not exactly parallel.

Because this transition is outside the focus range, the effect is not visible and there is no static transition.

701 (50 %)

Measured at the darkest point on the edge of the filter glass, the neutral grey half of this B+W 701 grey graduated filter has a transmittance of 50% (equivalent to +1 f-stop).

This darkens the relevant subject area by one f-stop without affecting the color. If, for example, the sky is too bright in relation to the landscape, this is the ideal value for good cloud depictions and a perfect blue sky that does not look faded as a result of overexposure.

Coating: MRC

702 (25 %)

Due to the light attenuation now being twice as strong i.e. by two f-stops (transparency 25%, max. 2 f-stops), even this graduated filter can produce quite dramatic effects.

Because of the increased difference in brightness, and to avoid an unnatural impression, it is even more important in this case that the horizon line is not too far from being the centre of the image.

Coating: MRC
