Went to a car show over the weekend and only took this one shot. The owner was a really good sport. I saw the shot when I first got there, set up and waited for the sun to go down and the other cars next to it and people to leave.
It took me about 20-25 minutes of 'figdeting' with my tripod/ball head to get most everything the way I wanted it, then 2 hours of 'standing guard' to make sure nobody came along and 'bumped' against my pod with so many people in the crowded street wanting to check out his ride.
I didn't think about it at the time, but I should have only had the headlight on for about 3-4 seconds rather than the full 15 seconds ... ahhh, live & learn.
