How many stops of ND do I need?
Common strengths of neutral density (ND) filters are 3-stop, 6-stop, and 10-stop. I recommend that you start with a 6-stop, but any of them will be fine. I find that a 6-stop filter is powerful enough to achieve virtually any goals I might have in terms of lengthening my shutter speed.
How do you calculate a 10 stop ND filter?
1. Simple Math. For a 10-stop ND filter, if the base shutter speed (without filter) is ¼ seconds, with the use of 10-stop ND filter, the exposure time becomes ¼ x 210 = ¼ x 1000 = 250 seconds.

Since a 10-stop ND has 10 stops of light-blocking power, that means you need to use a shutter speed that’s 10 stops slower to compensate.
