Photographer Nicolaus Wegner, 34, pictures his 32-year-old wife Daow, dangerously close to tornados, hurricanes and lightning storms with her back to the camera. The couple use forecast tools to predict where storms will show before chasing them down and waiting for them to materialise. Most of their shots are taken across Wyoming, U.S., but sometimes they travel to neighbouring states like Montana and Nebraska. [Photo/chinanews.com]
