Designed for mobile phones and compact camera systems, the P1 Prosories ND64 Filter from NiSi provides a 6-stop reduction in exposure, which allows the use of wider aperture settings for shallow depth of field, or slower shutter speeds for motion blur. This filter is built using high-quality glass with a nano coating that helps to prevent the loss of details. Also featured is a double-sided and multi-layered coating, water and oil resistance, and low reflectivity. This filter will not alter the color of your images.
