Neutral density camera filter B&W 810 MASTER, 58 mm, MRC coating

The B&W 810 MASTER neutral density (ND) camera filter, 58 mm with Multi Resistant Coating (MRC), reduces light transmission by ten f-stops to enable long exposures and wider apertures in bright conditions. Made from finely ground and polished special optical glass, the filter maintains lens image quality while delivering uniform, color-neutral attenuation across the visible spectrum. A multilayer anti-reflective coating and a final dirt- and water-repellent outer layer protect the glass, reduce reflections and simplify cleaning. The ND strength produces dramatic long-exposure effects such as misted water surfaces and motion-blurred people, while requiring stable support and appropriate exposure technique.

Advantages

The 10-stop light reduction permits substantially longer exposure times or the use of much larger apertures in daylight, giving creative control over motion blur and depth of field. High-quality optical glass and precision polishing preserve sharpness and do not degrade high-end lenses. The thin-film coating system includes seven anti-reflective layers per side for minimal flare, plus a durable outer coating that repels dirt and water for easier maintenance and longer service life. The filter produces largely color-neutral results, helping to avoid complex color correction in post-processing.

Suitable for

• Landscape long-exposure photography to smooth moving water and clouds
• Portraits using wide apertures in bright light to achieve shallow depth of field
• Urban long exposures to blur people and traffic or create light trails
• Time-lapse or creative motion-blur sequences

How to use

Attach the 58 mm screw-in filter to a lens with matching thread and secure it evenly to avoid tilt. Compose and focus before mounting the filter when possible, since dense ND filters make optical viewfinder composition and autofocus more difficult. For very long exposures use the camera’s bulb mode or long-exposure settings, set exposure values manually, and select a low ISO to minimise noise. Use live view, a remote release or camera app and cover the viewfinder to prevent stray light. Deactivate in-camera long-exposure noise reduction if you prefer to handle noise in post-production and shoot RAW to retain maximum editing latitude.

Usage recommendations

Use a stable tripod and remote shutter control, calculate exposure time adjustments for the 10-stop reduction (apps such as the B+W ND Calculator can assist), and avoid using the filter for direct solar observation. For best results, clean the outer coating with a soft cloth and avoid abrasive cleaners; always remove the filter when not required to prevent unnecessary handling and potential contamination.
