So after testing ND1000 I went to an old sea station here in Mariupol to try it out in natural conditions. I used set from 3 filters that gave a lot of vignetting (but I really like it) and exposure of 90 seconds.

wow... i JUST clued in...the water is all like soft and foggy looking because of your long exposure right? I always see pictures like this and have no idea where people capture such foggy looking water but I get it now. beautiful photo btw
