Above is another shot from a recent attempt at improving light streak techniques.
The shot was taken along Route 315 in Pittston Township. This has become one of my "go to" locations. First, you're in a parking lot, safely above the road. Second, it's near a truck stop, busy 24/7. Third, tractor trailers make great light streaks because they have so many lights, and at different levels.
I wouldn't call this a particularly great shot. There wasn't much traffic at the time, but I do like the curved streaks, hanging in mid air.
