Circular ND32000 (4.5) 15 Stop

The NiSi Circular ND32000 or 15 Stop ND Filter creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than usually required. By slowing your exposure time or increasing your aperture, you can control the depth of field and convey movement in your images. The ND32000 (15 Stop) is widely used to capture extreme long exposure images (usually 3-6 mins in daylight), to create effects like cloud movement or cloud softening.
