This is a picture I took last week when I was visiting San Francisco. It is was about 5pm and the sun was setting. I was almost to the south tower of the Golden Gate Bridge when I noticed the clouds in my sight ahead. I love the contrast between the light in the sky and the darkness of the cars and bridge. We get a strong source of light in this picture, as the light is prominently coming from the right. It is really interesting in this picture how we can see the many hues that the sun is reflecting into/onto the clouds.
