I took this photo on a recent trip to San Francisco. We were on the ferry returning from Alcatraz and the sun was setting behind the Marin headlands creating a wonderful silhouette of the Golden Gate Bridge.
I metered from the sky at the edge of the sun, locked exposure then recomposed using the bridge as a focal point.
As the boat was rolling up and down a lot I did take a lot of exposures to ensure I captured the bridge sharply. I was also able to track the sun as it got lower and lower. I lucked out with a sailing boat in the frame of some of them - which I couldn't actually see at the time because it was so bright!
A small amount of PP in ACR - straightened the horizon a little and a tiny bit of fill light to bring out the detail of sailing boat.
It was my first attempt at sunrise or sunset so I was rather pleased.
