NiSi Filters Australia Exposure Calculator
Use the NiSi Filters Australia 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.
Available FREE on the Apple App Store and Google Play Store.
