NiSi Filters Exposure Calculator

Use the NiSi Filters app to calculate the exposure time when using NiSi ND filters. Select a base/normal shutter speed before adding a filter to the camera.  Then select your filter and the new exposure time will be calculated. If the exposure time is over 30 seconds a timer will also be available to countdown the exposure time.
