The NiSi Filters 100mm ND Long Exposure Kit (NIP-100-EX-KIT) is a new kit from NiSi Filters featuring four 100x100mm IR Neutral Density Filters, ND8 3 Stop and ND64 6 Stop, ND1000 10 Stop and ND32000 15 Stop. Neutral density (ND) filters uniformly reduce the amount of light entering the lens. The ND Filter can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed. ND filters are also helpful when the contrast between the highlights and shadows is too high to get a quality exposure. The ND8 3 Stop is commonly used for waterfalls and capturing water flow at shutter speeds from 0.5 seconds to 2 seconds. The ND64 6 stops ND filter is generally used during golden hour to create exposures of 1-2 minutes for smooth water or clouds or is also great for capturing dynamic water while retaining some texture before the golden hour. The ND1000 10 Stop is used during the day outside of golden hour as the bright ambient light requires much more 'light blocking'. These can prolong exposures for up to 5 minutes during golden hour with the appropriate settings. A 15 stops filter can be used to achieve very long exposures in the middle of the day and with this filter, exposures upward of 5 minutes can be achieved even during bright sunshine. The NiSi Filters 100mm ND Long Exposure Kit also includes a NiSi soft filter pouch that holds four 100x100mm filter (or four circular filters up to 95mm), a cleaning cloth and four replacement foam gas
