ND filters Take it slow

An ND filter is essentially a dark sheet of glass that cuts down light transmission, lengthening the exposure time and rendering moving elements in your scene into a blur. It’s perfect for giving lapping waves, raging rivers or thundering waterfalls a wonderful misty quality, or turning fluffy clouds into exaggerated streaks on a windy day. Our kit came with six-stop and 10-stop varieties, which would turn a 1/30 sec exposure into 2 secs and 30 secs respectively. Though you can use tables to work out exposure times, Nisi produces a handy companion app to calculate the exposures for you.
