A glass filter that reduces exposure by approximately 15 stops.
The Super Stopper is a neutral density filter that reduces the light entering your lens by 15 stops.
It gives the photographer an opportunity to shoot during the middle of the day, even in bright sunlight. Traditionally, such conditions were considered unfavourable for photography, because of the harsh nature of the light. However, with the Super Stopper filter fitted, the softness that arises from any movement contrasts pleasingly with areas of bright light, creating an effect rarely seen in photography before now.
