Neutral density camera filter B+W 803 MASTER, 82 mm, Multi Resistant Coating (MRC)

The B+W 803 MASTER neutral density camera filter, 82 mm with Multi Resistant Coating (MRC) reduces incoming light by three f-stops to allow longer exposures or wider apertures in bright conditions. Constructed from finely ground and polished optical glass, the filter maintains high image quality and is designed to be optically neutral across the visible spectrum. A multi-layer anti-reflective coating on both sides and an outer dirt- and water-repellent layer protect the filter surface and simplify cleaning. Supplied as a single 82 mm screw-in filter, it is suitable for landscape, portrait and creative long-exposure photography as well as video work where aperture selection is limited.

Advantages

The B+W 803 MASTER offers consistent three-stop light reduction with minimal color shift, ensuring color-neutral results. High-quality special glass preserves lens sharpness and resolution. Multi Resistant Coating includes seven anti-reflective layers per side plus a protective top layer that repels dirt and moisture and eases maintenance. Thin-film coating technology produces uniform attenuation across the visible range and reduces reflections that could otherwise degrade contrast. The 82 mm screw mount gives secure attachment to compatible lenses.

Suitable for (tasks / use cases)

• Long exposure landscape photography to smooth water and cloud movement
• Portraits that require wider apertures in bright light to achieve shallow depth of field
• Video shooting where shutter/aperture cannot be changed sufficiently and neutral density control is needed
• Creative wipe and motion blur effects, light trails and continuous exposure effects

Key specifications

• Filter type: neutral density (ND), 3 f-stops attenuation
• Filter thread size: 82 mm screw-in
• Optical material: finely ground and polished special optical glass
• Coating: multi-layer anti-reflective coating (7 layers per side) with outer dirt- and water-repellent layer
• Light attenuation: uniform across the visible spectrum, color-neutral performance
• Construction: single-piece circular screw-in filter
• Typical applications: long exposure, portrait shallow depth-of-field, video ND control

How to use

Screw the 82 mm B+W 803 MASTER ND filter onto the front thread of a compatible lens until it seats securely; avoid overtightening. Compose and meter the scene with the filter attached or use exposure compensation/neutral density calculation to determine the required shutter speed for three stops of light reduction. For video, set shutter and ISO as needed and use the filter to control exposure while maintaining aperture choice. After shooting, clean the filter surface gently with a soft brush or microfiber cloth and, if needed, a few drops of lens cleaner applied to the cloth.

Usage recommendations

Use the filter when you need consistent three-stop attenuation—typical for creating motion-smoothing effects on water, extending shutter times in bright conditions, or achieving shallower depth of field for portraits when aperture alone cannot provide the required exposure. Protect the filter with a case during transport and clean only with appropriate lens-care materials to preserve the MRC coating.
