Hey Alex


A bit over a year ago I bought 2 B+W ND filters for long expo shots, the 106 (0,6?) and the 110. (1.?) Great filters, lots of fun with those, but I don't know about MRC, and to be honest, I didn't really pay attention to it so I can't advice you on that.


After a while of using I think I can tell you that the 0,6 will be enough to do streams and waterfalls since this is not 30+sec were talking about but for that creamy/misty sea effect I think you need the 0,9 or higher? Sometimes when I really want to get upto 4 minutes or longer I put them over each other to kinda double their effect.


Hope this was of some help and good luck!
Jorund.
