LEE Seven5 Super Stopper

The Lee 75x90mm Seven5 Super Stopper ND glass filter reduces the amount of light entering the lens by 15 stops. Its 4.5 density and 32,000 (15 stop) filter factor means that an ordinary 2-second exposure will take over 17 hours to expose through the filter, allowing you to photograph with a wider aperture or slower shutter speed in bright daylight. By greatly extending exposure times the Super Stopper has the effect of allowing anything that is moving in your image to become blurred or ghost-like (e.g. clouds, water, people, traffic, etc.). For use with the Lee Seven5 Filter Holder (not included)
