You can even combine this filter with other filters such as graduated neutral density filters to achieve additional special effects. The 4 x 4" format gives you the freedom to use the PROSTOP with many different lenses and is made to exacting standards. It is best used for outdoor, nature and location photography. The PROSTOP is designed with a special rubber gasket surrounding the filter to help prevent any ambient light from intruding into the image.
