Taken at Ogmore on the Heritage Coast in S. Wales UK.
I've actually desaturated the foreground as it was very blue even though I used the cloudy white balance.
It was the last shot of the evening and it was really dark by then.
I had a habit of over-gradding the sky with my ND grad filters, so be careful and don't do it, you know it makes sense ;o)
Better off blending images or doing HDR when there are objects above the horizon.
