This was taken from Fort Baker on the North side of the Golden Gate Bridge looking south at the SF skyline. You can see the Bay Bridge off to the left and Coit Tower to the right of it. To the right of Coit Tower you can see the Transamerica Pyramid.
This was a long exposure at 90 seconds. For this image I really didn’t do too much although it might look it. I added some contrast, the overall blueish tone and one gradient.
