The Urth 77mm Ethereal 1 Black Mist Filter Plus+ is a high-quality photographic filter that enhances image quality through controlled light diffusion. This 77 mm diameter filter creates subtle halo effects around bright light sources while maintaining overall image contrast and sharpness, making it suitable for photography and videography. The Black Mist technology reduces harsh lights without causing significant color shifts, resulting in naturally looking images with atmospheric depth. Made from high-quality optical glass, the filter features a multi-layer nanocoating that minimizes reflections, lens flares, and ghosting while providing protection against water, oil, and dust. The slim aluminum frame ensures compatibility with lens hoods and prevents vignetting with wide-angle lenses. This filter is the successor to previous diffusion filters with improved light transmission properties. The neutral density effect is approximately 1 stop, allowing for creative exposure control under various lighting conditions. The filter threads are precision-crafted for smooth attachment and detachment from compatible 77 mm lenses. Ideal for portrait, landscape, and cinematic applications where controlled light diffusion is desired without sacrificing image sharpness. The filter offers consistent performance in temperatures ranging from -10°C to 40°C. Weighing about 45 g, it adds minimal bulk to camera setups while providing lasting protection for lens elements. The product comes with a protective storage case to prevent scratches during transport and storage.
