Just got a new Haida ND3.0 filter so gave it a try on holiday at Sandsend near Whitby on the weekend, see what you think:
This was taken at f11 / 30 secs about an hour before sunset, and is the first time i've tried such a hard-stopping ND filter, and although its a bit of a bland effort, i'm hopeful for some good potential with it as I get used to it.. hope you like, comments very welcome

Cheers, Graeme
