Ok, I give up. here is the Lee 10 & 6 stop filters, which increase exposure time. But HOW do they do that?!
LEE Stop Filters for Long Exposures
Great pic, I see now how its blurred the ocean but kept the pier in sharp focus. Very nice
Basically the Lee 10 stop filter is like putting a welding goggle infront of your lens, it cuts the light entering your lens by 10 stops, which is basically about 1,000 times longer than the metered speed. There are great ND Calc aps that allow you to calculate the correct exposure, as you can't meter once you fit the filter.
They are mainly used for seascape and moving water and sky shots.
This shot is from flickr, showing how you can create interesting skies...

ND (neutral density) filters come in many variants, these can be helpful if you want to shoot at a wide aperture say f1.8 to get shallow depth of field on a bright day.
