I wanted to take a long exposure shot of the ocean to get smooth water but also have crisp, shadowy, ominous storm clouds.
Since a long exposure shot would make both the water and and the clouds look "creamy" I had to combine a short exposure and a long exposure.
And since it was the middle of the day, I had to use a high f/stop value (f22) for the long exposure along with a ND filter to remove some of the light.
Then I touched up the shots and copied/pasted the clouds from the short exposure to the long exposure (since the horizon line is so flat) - basically a manual HDR.
