Former prison - Alcatraz in San Francisco bay (http://en.wikipedia.org/wiki/Alcatraz_Island). Taken in March 28 of 2010.
It is absolutely incredible to be in San Francisco in the morning to watch the sun rise and see how thick fog just rolls over the hills. This was one of those mornings The fog completely isolated the Alcatraz, and the rising sun behind it added the drama in the sky.
I do not recal all the technical details, but remember that I used a 70-200 f4 IS lens to zoom in closer, and a 3 stop GND filter to balance the bright sky. May be a polirizer as well.
