The 100 x 100mm Super Stopper ND Filter from LEE Filters is an ND filter with a 32,000x filter factor that provides a 15-stop exposure reduction. Its 4.5 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
This Lee Filters 100mm-series Super Stopper neutral density filter is constructed from optical glass for clarity as well as color fidelity and features a built-in gasket. This gasket works with a compatible LEE Filters 100mm System filter holder to help form a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in between the filter and the lens behind it.
