Filter B+W 77mm Yellow 495 MRC Basic for camera lenses, 77 mm thread

B+W 77mm Yellow 495 MRC Basic is a screw-in lens filter with a 77 mm thread designed to modify color contrast and tonal separation. The Y495 (yellow) transmission shifts the relative brightness of colors in the image, which is especially useful in black-and-white photography to control sky and foliage contrast and to subtly alter skin tones in portraits. The MRC (Multi-Resistant Coating) reduces surface reflections, improves light transmission and helps repel dust and moisture to maintain image clarity.

Advantages

The yellow 495 filter provides predictable contrast control for monochrome work and selective tonal adjustment in colour photography without influencing exposure dramatically. The MRC coating improves flare resistance and ensures more consistent color rendition by minimizing unwanted reflections. The screw-in 77 mm metal mount offers secure attachment and compatibility with lenses that accept 77 mm filters.

Suitable for

• Black-and-white landscape photography to darken skies and enhance cloud definition
• Portrait photography to subtly affect skin tones and midtone separation
• Creative colour photography where selective contrast between foliage and sky is desired

Key specifications

• Filter type: Yellow 495 contrast filter
• Mount thread: 77 mm screw-in
• Coating: Multi-Resistant Coating (MRC) for reduced reflections
• Construction: slim metal ring suitable for standard lenses
• Optical effect: alters tonal separation and contrast, primarily used for monochrome results

How to use

Screw the filter onto the front of a lens with a 77 mm thread until it is finger-tight. Compose and meter exposure as usual; the yellow filter typically requires no exposure compensation for modern digital workflow, but check results and adjust settings if necessary when working in challenging light. For black-and-white photography, use the filter to increase contrast between sky and foliage or to change tonal relationships; for portraits, observe how midtones and skin textures respond and adjust lighting or camera settings accordingly.

Usage recommendations

Store the filter in its protective case when not in use to protect the MRC-coated surface. Clean with a soft microfiber cloth and an appropriate lens cleaning solution to avoid damaging the coating. Test the effect at different apertures and focal lengths to familiarise yourself with how the yellow 495 filter influences contrast and tonal separation in your shooting conditions.
