I was in San Fran about weeks ago for the SF Bay Photowalk 2013. This image is from the Saturday morning when I co-led the Architecture workshop with the awesome Steve Landeros, Brian Day and Nathan Wirth.
This is an image of the less famous Bay Bridge and Pier One, along the Embarcadero in San Francisco looking towards Treasure Island.
It was an amazing day and a joy to see so many photographers lined up along the waterfront. I loved every minute of being there and the fact that I got an image or two that I'm really happy with is a huge bonus.
I used a 10 ND filter, and stacked a 3 and 1 stop hard grad ND filter, to get the right level of contrast in the the clouds, water and around the pilings.
The techie stuff:
Sony A850 D-SLR
Zeiss 16-35mm Lens
Exposure: 235 seconds
Focal Length: 16mm
