While I was waiting to take pictures of the Pirate Tower a few weeks ago, I diddled around taking some other pictures too. In particular, while the sun was still up, I set a high shutter speed and took some pictures of the surf crashing against the rocks. My camera didn't appreciate this, but it did produce a few interesting images.
I love how the water turns black against the sky, very striking. I've heard of the sea looking "inky", but this takes it to a new level!
Must be the wine dark sea.
Great photo!
You should experiment w/ gradient filters in Photoshop.
I love laguna.
