Brick Doorway, Fort Point
_I photographed this image on January 27, 2012. Fort Point is located
under the San Francisco end of the Golden Gate Bridge. Work on building
Fort Point began in 1853 and it was completed around 1861. It became a
National Historic Site in 1970.
For this image I used 2 Sigma DP1 digital cameras mounted next to each other on a panoramic device I constructed which allows the cameras to rotate up or down around what is called the entrance pupil of the lens. This enabled me to tilt the cameras slightly downward to make one part of the image, then slightly upward to make the other part of the image. I blended the two parts of the image together using a computer program called Panorama Tools Graphic User Interface (PTGUI for short). The exposures were 5 seconds at f/8 (ISO 50). You can see the image in the format you prefer by clicking on one of the following: parallel, cross-eyed, or anaglyph (red/cyan glasses).
