How to determine the stops of an ND filter
« on: October 13, 2017, 02:28:38 AM »
I was given a couple of ND filters by a friend who does not used them anymore. However the ND filters are not marked as there are no indications of how many stops are the filters.

Is there an easy way to determine how many stops an ND filter is??

Please help.
Thanks!

I didn't find the right solution from the Internet.
