The DJI Osmo Pocket and Pocket 2 ND16 filter from Freewell Gear decreases the amount of light entering the camera lens by 4 f-stops. This is helpful in balancing the image perfectly and capturing sharp footage in normal daylight conditions. Apart from slowing down your shutter speed, the ND filters are also effective in avoiding the unwanted 'Jell-O' effect which is often seen in footages captured without ND filters.
