Fog. I was down in Wilmington DE for a short while this afternoon. This was in rain and fog with my little Panny LumixPanasonic Lumix LX5, 1/125th second, F2.7, ISO 80, handheld. Converted to BW in LR3Shot in the 1:1 Square format. I didn't mean to, but it was raining so hard I didn't pay attention I just shot and headed back to my meeting.
