We were skimming over the water with Alcatraz in the close foreground and the city in the background. There is no problem flying low over water such as San Francisco bay. We came in high (the legal height) over the Marin Headlands (GG Bridge north tower) and dropped in very quickly to get low over the water for the shot. We did this several times in order to guarantee the proper angle and perspective. I used a different focal length on each pass. Turns out that I used the shot with my 24mm lens in the publication. So, in reality, DOF turned out to not be an issue. But shots using my 135mm lens certainly could have been. Hence f/11 rather than f/8. Safety factor. JB
