Our flight back from Amsterdam was a little delayed, so we had some fun doing long exposures on the people-mover belts. These shots were inspired by Shane Mielke, by the way. It seems he had a steadier conveyor belt, though.
EXIF: f22 for 3.2 seconds at ISO 100. It was really bright, and the longer exposures ended up too blurry - at least on the little display on the back of my trusty 5D.
