Northstar at Nicollet Island; Minneapolis, MN
Eight cars worth of Twins fans have just witnessed an exciting 9th inning rally to defeat the much hated White Sox. This is a "Twins Special" crossing the Mississippi River onto Nicollet Island.
The motion effect here is achieved with a technique called "zoom panning," where the camera pans from side to side to follow the subject, the zoom is pulled out to keep the size of the subject the same as it approaches, and the shutter is held open longer than usual (1/30th of a second, in this case) to capture the blur of all of that motion.
