However, he left his truck engine running, and the truck caught fire. The trucker ran out to his truck, straight from his bath, stark naked. Maitani couldn’t photograph this once-in-a-lifetime shot because he didn’t have a camera with him. This, so the story goes, inspired him to create a camera that was so small it could be taken everywhere: the XA..."
