Also, does each ND filter stop equal 3 fstops? thanks Fernando Mol replied 15 years, 6 months ago 2 Members · 1 Reply 1 Reply Fernando Mol March 1, 2011 at 6:39 pm I think it’s ISO 200. HPX170 is ISO 400. Best way to be sure is to use a SLR, a Grey Card and compare the exposures. Reply to this Discussion!
