I hadn't made too many long exposure images until fairly recently. But inspired by some of the work I've seen by +Josh Haftel and his minimalist long exposures, I decided to give it a try at the coast this spring. At just 20 seconds, this isn't that long an exposure but its enough to smooth out the water a bit.
