As an upgrade from the previous LEE Filters Big Stopper range, this high-end optical filter affords 10-stops of light reduction in the following sizes; 67mm, 72mm, 77mm, and 82mm. This makes any form of moving subject within your frame blurred or ghost-like, such as clouds, waterfalls, rivers, and the ocean. In short, this allows for increased flexibility when experimenting with exposure lengths.
