Hoya 52mm Yellow Green Multi Coated Glass Filter

The Hoya 52mm Yellow Green Multi Coated Glass Filter (X0) #11 is a specialized optical filter designed for black and white photography. It works by selectively absorbing specific wavelengths of light before they reach the sensor or film, darkening reds while absorbing green and green-blue tones. The practical result is more flattering and natural-looking skintones when photographing portraits under tungsten lighting, and increased tonal separation in outdoor scenes featuring foliage, grass, and other greenery. For black and white landscape photographers, this translates to richer contrast between sky, vegetation, and earth tones.

Built from high-quality optical glass with Hoya's multi-coating treatment on both surfaces, this filter minimizes reflections and internal flare that could otherwise reduce image contrast and sharpness. The multi-coating also provides practical benefits, making the filter surface easier to clean and more resistant to fingerprints and environmental contaminants. The 52mm thread size is compatible with a broad selection of lenses from various manufacturers. While this is a specialized filter with limited application outside monochrome work, it delivers an optical effect that is authentic to traditional black and white photographic techniques and provides a level of tonal control that differs from digital post-processing simulations.
