The day after winter solstice, Bay area weather was crisp and clear, but with incoming rain clouds. I photographed Point Bonita and its lighthouse from Hawk Hill. In the other direction, I could see the Golden Gate and downtown San Francisco.
I intentionally extended the exposure to five minutes by using a small aperture. The point was to create the star effect on the rotating lighthouse beacon. This also visually stretched out the rain clouds as they moved in front of the camera exposure.
