Sometimes I look at the classic paintings and ask myself why is long exposure more popular than the shorter one? And I often try to capture the water in all it's beauty and dynamics and energy with as short exposure as reasonably possible.
Excellent image. I generally prefer shortish exposures in the 1 - 4s range for showing the energy of the sea rather than the super smooth look.
but you could have taken this with 1/250 or such
There are some scenes where a very short exposure, freezing the water, is best; there are others in which a very long exposure, reducing the water to a hazy sheen, works best; and there are others where a moderate exposure works well. There are no absolutes. The exposure you have used here gives a very lovely result, but I don't see any virtue in "as short exposure as possible".
