BIG Stopper

The Big Stopper is a long exposure glass filter that reduces exposure by approximately 10 stops. Long exposure filters are used to extend the length of an exposure (shutter speed). Extending the shutter speed allows anything that is moving in your image to become blurred or ghost like. Subjects such as clouds, waterfalls, rivers and the sea work particularly well. However the effect is not limited to landscapes, the filter can also be used on cityscapes to blur people or roads and highways to blur traffic.
