Now I must confess that I had to do a little work on this one. It may have been a candidate for an HDR composition but those are a little difficult to accomplish with a moving ocean (or a moving anything, come to that) so instead I availed myself of the data available in the raw image.
I whacked on two Levels adjustment layers. The top one shifted the black point inward a little to boost the contrast and shifted the midpoint a tad darker to bring back the colours of the sky. I then masked out the ground area so that it wouldn't be affected by it. (Since the ground was originally lost in shadow, and certainly needed no darkening.)
The second one effectively did the reverse; pushed the white marker in a little and shifted the midpoint lighter, then masked out the sky so that it applied only to the ground. Thus I recovered the greens of the grass (which were completely lost in the default upload).
The result is that I got a pretty moody representation of both land and sea, if I do say so myself.
(Though the thumbnail looks awful.)
