Neutral Density Graduated Filter B+W Basic 702 Graduated ND 25% MRC 77mm (model 1102735)

B+W Basic 702 Graduated ND 25% MRC 77mm is a graduated neutral density filter that darkens a portion of the frame by 25% to help balance exposure between bright skies and darker foregrounds. Designed for 77mm lenses, the filter uses a graduated density transition to reduce highlights while preserving detail in shadow areas. The multi-resistant coating (MRC) reduces reflections, eases cleaning and improves durability for regular outdoor use.

Advantages

The graduated neutral density effect provides controlled light reduction across part of the image without altering colour balance or contrast significantly. The 25% density step is suitable for subtle correction when the sky is only moderately brighter than the foreground. The MRC surface treatment minimizes lens flare and ghosting, simplifies maintenance and increases resistance to fingerprints and moisture. The 77mm threaded mount offers straightforward attachment to compatible lenses and stable alignment for repeatable compositions.

Suitable for

• Landscape photography with bright skies and darker foregrounds
• Coastal and sunset scenes where horizon exposure differs from foreground
• Architectural exteriors requiring controlled highlight reduction
• Long exposures where graduated light control improves final balance

Key specifications

• Filter type: Graduated neutral density (soft transition)
• Density reduction: 25% (approximately 0.3 ND / 1/3 stop)
• Diameter: 77 mm threaded mount
• Coating: Multi-resistant coating (MRC) for reduced reflections and easier cleaning
• Material: Optical glass element with coated surfaces
• Transition: Graduated (soft edge) suitable for horizons and gentle slopes

How to use

Mount the filter on a lens with a 77mm thread or place it in a compatible filter holder aligned to the horizon or subject where exposure control is needed. Compose the scene and orient the graduated transition so the darker area covers the brighter portion of the frame, typically the sky. Adjust exposure settings after mounting the filter; use live view or a histogram to verify balanced highlights and shadows. For precise control, combine with bracketing or exposure compensation as required.

Usage recommendations

Use the filter when the brightness difference between sky and foreground is moderate; the 25% reduction is intended for subtle correction. Clean the MRC-coated surfaces with a soft microfiber cloth and lens-safe cleaner. Store in a protective case when not in use to avoid scratches and dust. For scenes with abrupt transitions or very bright skies, consider stronger graduated densities or hard-edge variants.
