The B + W 37mm SC 110 Solid Neutral Density 3.0 filter is an ND filter with a 1,000x filter factor that provides a 10-stop exposure reduction. its 3.0 density creates a darkening of the entire image, allowing you to shoot with a wider aperture or slower shutter speed than is normally required. by decreasing the exposure time or increasing the aperture, you can control the depth of field and transmit motion more easily. neutral density filters do not affect the colorization of the image and are ideal for image colorization.
To avoid internal images and reflections, each glass surface includes a layer of anti-reflective coating. B + W filters are constructed with Schott glass for optical clarity. This filter features an F-Pro brass filter ring for durability and jam prevention.
