The natural arch known as the Green Bridge, it was captured during golden hour.
 I liked the way ambient light was catching part of the arch and contrasting it against the shaded areas. I decided to expose the shot for 30 seconds to create further interest in the interaction of the choppy sea around the arch and rocks, with the intention of smoothing out the sea and creating a greater amount of white water, which I'd hoped would contrast further against darker areas around the arch. I was quite happy with the end result.
