The B + W 100 x 100 mm XS-Pro MRC-Nano 810 solid neutral density 3.0 B + W 100 x 100 mm XS-Pro MRC-Nano 810 is an ND filter with a 1,000x filter factor that provides a 10-stop exposure reduction. it is compatible with a 100 mm B + W filter holder and its 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than is normally required. by reducing the exposure time or increasing the aperture, you can control the depth of field and transmit the motion. by reducing the exposure time or increasing the aperture, you can control the depth of field and transmit the motion more slowly than is normally required. by reducing the exposure time or increasing the aperture, you can control the depth of field and transmit the motion.

The Nano coating associated with XS-Pro filters provides an additional eighth layer on the MRC, resulting in an improved flanging effect when in contact with water for greater cleaning efficiency.

The B + W filters are made of Schott glass for greater optical clarity, as well as color fidelity and measurements of 2.0 mm thick.
