Neutral density camera filter B&W 810 MASTER, 55 mm, MRC coating

The B&W 810 MASTER neutral density camera filter, 55 mm, MRC coating reduces incoming light by ten f-stops to enable very long exposures and wider apertures while maintaining optical quality. Constructed from finely ground and polished special glass and finished with a multi-layer thin-film coating, the filter delivers uniform light attenuation across the visible spectrum and neutral colour rendering. The outer layers provide anti-reflective performance and a dirt- and water-repellent surface for easier cleaning and maintenance. The single-piece pack includes one 55 mm ND filter designed for use with compatible lenses and requires stable support such as a tripod for best results.

Advantages

The ten-stop density allows dramatic extension of exposure times, turning flowing water into smooth mist and rendering moving subjects softly blurred or invisible. Multi Resistant Coating (MRC) minimizes reflections and reduces flare while preserving contrast. The finely polished optical glass maintains lens performance without introducing noticeable optical aberrations. The outer protective layer resists smudges and water, simplifying cleaning and prolonging service life. Colour-neutral attenuation and seven anti-reflective layers per side ensure consistent results across the visible range.

Suitable for

• Long-exposure landscape photography (waterfalls, rivers, seascapes)
• Creating motion blur effects in urban and street scenes
• Portraits that require wider apertures under bright light
• Night and low-light creative exposures with tripod support
• Photographic techniques requiring precise exposure control

How to use

Mount the 55 mm B&W 810 MASTER directly onto a lens with matching thread and ensure the filter is tightened without over-torquing. Because the filter reduces light by ten stops, use a stable tripod and a remote release or camera app to avoid camera shake. Set exposure values manually: select a low ISO, choose the desired aperture, then calculate the extended shutter time required with the ND effect applied. Use Live View to compose and check focus, and cover the camera viewfinder to prevent stray light during long exposures. For best post-processing latitude, shoot in RAW and disable in-camera long-exposure noise reduction if you plan to perform custom noise reduction in software.

Usage recommendations

Do not use ND filters for direct solar observation; they do not protect against UV and IR radiation and can cause eye damage. For long-exposure photography use a solid tripod, manual exposure settings, remote trigger or camera app, and low ISO. Consider the B+W ND Calculator App to determine correct exposure times and take care to protect the filter surface—clean with appropriate microfiber cloths and lens solution.
