The NiSi Nano IR Neutral Density Filter ND32000 is the perfect tool for landscape photographers. Made from high-quality optical glass with a nano coating, this filter ensures that not a single bit of detail is lost, and your images are true-to-life in color and clarity, no matter the conditions. The 4.5 density provides a 15-stop reduction in light from entering the lens, making it ideal for capturing extreme long exposure images.Neutral density filters like this do not affect the coloration of the image, but they create a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. This gives you greater control over the depth of field and the ability to convey movement in your images. The ND32000 is specially designed for capturing extreme long exposure images, usually lasting from 3 to 6 minutes in daylight. This enables you to achieve creative effects like cloud movement or cloud softening, resulting in breathtaking landscape images.Using neutral density filters makes the camera vulnerable to infrared light, which casts an unwanted red color to the photos when shooting at a small aperture. However, the NiSi nd filters come with added infrared protection that helps to eliminate the infrared light through the lens to ensure natural color. This feature ensures that your images are true-to-life in color and clarity.Thanks to its slim aluminum frame with knurled edges, the ND32000 filter is easy to install and allows for stacking of UV, CPL, or other ND filters, making it a versatile accessory to achieve a range of creative effects with your camera. The coating also makes the filter waterproof, scratch-resistant, and anti-reflective, so you can use it in any environment without worrying about damage.In conclusion, the NiSi Nano IR Neutral Density Filter ND32000 is an essential accessory for landscape photographers who want to take their photography to the next level.
