The Hitech 4 x 4 inch 2.4 Neutral Density PROSTOP 8 Stop has been designed for use on long exposures. It is primarily used to control the image on longer exposures allowing use of much slower shutter speeds. The visible effects created by using longer exposures is the effect of motion blur on any movement within your pictures, such as clouds, waterfalls, seas and rivers. The PROSTOP filter is fitted with a foam gasket perimeter, which creates a seal between the filter holder and lens, thus reducing light spillage around the sides of the filter.
