Circular Filter B+W Red Dark 630 MRC 72mm (model 1102703)

B+W Red Dark 630 MRC 72mm is a screw-in photographic filter that produces a strong dark red color cast to alter color balance and increase contrast, particularly for black-and-white and creative color photography. The filter is sized for lenses with 72mm filter threads and uses a multi-resistant coating (MRC) to reduce surface reflections, minimize flare, and make the glass easier to clean. Constructed to fit standard 72mm lens mounts, it provides a reliable optical accessory for photographers seeking controlled, high-contrast effects and color filtering in-camera.

Advantages

The filter offers a pronounced red transmission that shifts color balance and deepens tonal separation without the need for post-processing. Multi-resistant coating reduces stray reflections and improves light transmission, while the screw-in metal mount ensures secure attachment and alignment on lenses with 72mm threads. The optical glass maintains image sharpness and is suitable for both color and monochrome work where strong red filtration is required.

Suitable for

• Creative color photography requiring a deep red cast
• Black-and-white photography to increase contrast and darken skies
• In-camera color correction or special effect workflows
• Studio and outdoor shooting where controlled color filtration is needed

Key specifications

• Filter type: dark red color filter
• Mount type: 72mm screw-in thread
• Coating: multi-resistant coating (MRC) for reduced reflections and easier cleaning
• Optical material: coated glass element for image sharpness
• Effect strength: strong red filtration suitable for high-contrast and tonal separation

How to use

Screw the filter onto the front of any lens with a 72mm filter thread until it seats securely; avoid overtightening. Compose and expose based on the visual effect of the dark red cast — for accurate exposure, meter through the viewfinder or use a light meter and make adjustments for reduced transmitted light. For black-and-white work, evaluate contrast changes in preview or test frames and adjust exposure or development accordingly. Clean the coated surfaces with a soft microfiber cloth and appropriate lens cleaning solution to maintain optimal transmission.

Usage recommendations

Use the filter when you need strong red filtration in-camera rather than relying on digital post-processing. Allow for exposure compensation when working in low-light or with dense filtration, and store the filter in its case to protect the coated surfaces when not in use.
