A few years back, I've been trying to capture the fog roll in under the Golden Gate Bridge. I had several failed attempts, where the fog would not be there. This time, I got here just at the right time before the fog completely covered it entirely.
Canon 60D | ISO-125 | F-13 | 70-200mm 2.8 @70mm | 20 second expo | 10 Stop ND Lee Filter. My shot was underexposed by one stop, as I didn't want to over expose the clouds. I opened the RAW file in Adobe CC, I opned up the shadows and increase exposure by 1 stop. Cleaned up sensor spots and then reduce the blues as I had some color cast from the filter.
