LEE Filters SW150 Little Stopper Neutral Density 1.8 150 x 150 mm LEE Filters is a 64x ND filter with a filter factor that provides a 6-stop exposure reduction. 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than is normally required. By decreasing the exposure time or increasing the aperture, you can control the depth of field and transmit motion more easily. Neutral density filters do not affect colorization.
