Here is how it works. You set your camera to the correct exposure with the setting you want to use. Then you add your 10 stop or 15 stop ND filter. Set your aperture and ND setting in Long Exposure Calculator, and it will tell you the correct exposure time. Better yet, it has a stop watch to count down the seconds while your exposure is happening. Handy free app to have on your phone…
