No8 ND1000 Nano Neutral Density Filter HD, Waterproof, Scratch-resistant, 18x Nano Coating ND FILTER. The No8 ND1000 filter, made of high-quality optical gl, reduces the amount of light entering the lens to achieve very long shutter speeds in daylight or flash light without overexposure. The amount of light reduced by 10 aperture levels allows a thousand extended exposure time. This is useful for situations where motion blur is to be generated (rivers, waterfalls, moving people) or large apertures (e.g. F1.4 and larger) are to be used with flash or in the midday sun to avoid overexposure. The ND1000 filter allows the use of long shutter speeds to record movement in objects, such as waterfalls, leaving the flowing water silky soft and smoothed. The ND1000 filter also blocks ultraviolet light and reduces light exposure to prevent excessively bright images, resulting in a variety of creative possibilities in landscape photography (e.g. waterfalls). The filter is ideal for obtaining high-contrast and correctly exposed shots when shooting and filming outdoors in very bright conditions. The filter is also ideal for use on wide-angle lenses, as due to the slim but still very robust construction made of aviation aluminium, no filter-related vignetting (shadowing) occur in the corners of the image. The 18x Nano Multi-Resistance Coating (Multi-Resistance Coated) significantly reduces lens reflections and ghosting and makes the filter scratch-resistant, water-repellent, as well as oil and dust resistant. All features that are crucial to work effectively and professionally outdoors. Features The No8 ND1000 provides 10-stop light reduction to create long exposures and open-aperture shots in bright light (sun or flash). Recommended for landscape photography. An 18-layer nano multi-coating significantly reduces lens flare and ghosting, making the filter scratch-resistant, water-repellent, oil and dust resistant and suitable for the demanding demands of landscape photography.
