B+W Red Dark 630 MRC 55mm photographic filter (model 1102698)

The B+W Red Dark 630 MRC 55mm photographic filter is a screw-in colored glass filter designed to alter tonal rendition and contrast in both black-and-white and color photography. Fitting lenses with a 55 mm filter thread, this dark red filter shifts color balance and deepens skies and foliage tones when used with appropriate metering and exposure settings. The multi-resistant coating (MRC) minimizes surface reflections and helps maintain image clarity while improving scratch and moisture resistance for regular field use.

Advantages

The Red Dark 630 filter delivers predictable darkening of blue and green tones, producing stronger contrast and dramatic skies in monochrome images and richer warm tones in color work. The MRC treatment reduces flare and ghosting, ensuring higher contrast and better color fidelity under backlit or high-contrast conditions. The screw-in 55 mm metal mount provides secure attachment and consistent alignment with a wide range of 55 mm lenses.

Suitable for

• Black-and-white landscape photography to enhance clouds and sky contrast
• Portraits requiring warmer or more dramatic skin tones
• Artistic color effects and creative in-camera color control
• Outdoor photography where controlling blue and green channel response is desired

Key specifications

• Filter type: dark red glass screw-in filter
• Mount size: 55 mm screw thread
• Optical coating: multi-resistant coating to reduce reflections and improve durability
• Effect: strong attenuation of blue and green wavelengths for increased contrast and warm tone shift
• Material: coated optical glass with metal threaded ring

How to use

Screw the filter onto the front of any lens with a 55 mm thread until lightly snug; avoid overtightening. Meter and set exposure with the filter in place or apply an exposure compensation consistent with the chosen film or sensor response and the filter’s darkening effect. For black-and-white photography, use the filter to increase contrast between sky and clouds or to emphasize textures. In color shooting, evaluate white balance and adjust either in-camera or in post-processing to account for the strong red shift.

Usage recommendations

Clean the filter surface with a soft microfiber cloth and a lens-safe solution before use to prevent spots or reduced contrast. Store the filter in its protective case when not in use to avoid scratches and maintain the coating. When combining with other filters or stacked adapters, check for vignetting on wide-angle lenses and re-evaluate exposure and white balance.
