I actually kinda love this shot for what it isn't: accurate. It wasn't this foggy (though it sure felt like it), but the effect comes from the fact that my little Canon Powershot was in my bag next to a cold bottle of water. So when I brought it out and exposed it to the warmer, humid air, it fogged up the lens. I didn't realize it at first -- I thought it was just on the LCD screen -- and took the shot. Then I looked at the lens and saw the condensation, so this was the only shot I took.
