The Benro Master Glass Filter 100x100mm ND1000 (3.0) is a professional-grade neutral density square filter designed for serious photographers requiring precise exposure control. Measuring 100x100mm with a 4mm thickness, this high-density filter provides 10 stops of light reduction (ND1000, 3.0 density), enabling extended shutter speeds and wider aperture settings even in bright lighting conditions. Constructed from premium optical glass with advanced multi-coating technology, the filter features NANO WMC coating for superior water and oil resistance while maintaining easy cleaning properties. The ULCA multi-coating system effectively minimizes lens flare and chromatic aberration, ensuring optimal image clarity and color accuracy across the visible spectrum. With an average light transmission rate exceeding 99.0% between 420-680nm wavelengths, this filter maintains true color reproduction and image sharpness. The integrated IR CUT coating specifically addresses infrared pollution, preventing color casts and maintaining color integrity during long exposure photography sessions. This technical specification makes the filter particularly suitable for landscape, architectural, and creative photography where extended exposure times are required to capture motion blur effects such as flowing water, moving clouds, or urban traffic patterns. The scratch-resistant glass construction and durable coating ensure long-term reliability and consistent performance under various environmental conditions. Compatible with standard 100mm filter holder systems, this neutral density filter represents a practical solution for photographers seeking to expand their creative possibilities while maintaining optical quality standards. The neutral density characteristic allows for precise exposure control without altering color balance, making it suitable for both digital and film photography applications where accurate color reproduction is essential.
