Stopper filters are used for extending exposure times which has the effect of making anything that is moving become blurred or ghost like, for example clouds, waterfalls, rivers or the sea. Used creativity they can change the way we look at moving objects and capture a real sense of time passing in your images. Stoppers are not limited to landscapes and can be used to blur crowds of people, traffic or anything in motion.
The 100 x 100mm Super Stopper Neutral Density 4.5 Filter from LEE Filters is an ND filter with a 32,000x filter factor that provides a 15 stop exposure reduction. Its 4.5 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.
Why use a Super Stopper?
The new Super Stopper works well in harsh midday sunlight - traditionally considered an unfavorable time to shoot. However, with this filter the softness that arises from any movement contrasts pleasingly with areas of bright light, creating an effect rarely seen before now.
