How many stops of ND do you need?
What filter is best to use? For long exposure shots like below with clear water and blurred clouds you will want a 6 stop or 10 stop ND filter as this will give you an exposure time of at least 30 seconds and up to 4 minutes. The higher stop filters will enable you to get those long exposures.

Portraits can be beautifully enhanced by ND Filters for all the same reasons they make landscapes so interesting. You can play around with depth of field in bright conditions, and use motion blur to powerful effect.
