While most people head for cover at the first sign of a storm, this man runs straight toward it. Storm chaser and father of three Mike Olbinski is addicted to photographing extreme weather and regularly takes on tornadoes and supercell thunderstorms in a bid to capture extraordinary images. The photographer, from Phoenix, often travels hundreds of miles a day to reach the eye of a storm. He first became hooked on the unusual hobby almost a decade ago, following the birth of his daughter.

In this photo taken Wednesday, October 29, 2014, a fisherman catches a fish near the shores of Lake Chivero, west of Harare. Illegal fishing can be hazardous in Zimbabwe, where poachers scan the banks for armed rangers and the water for crocodiles while they cast their rods. The country is in such a dire economic state that thousands of people, unable to find regular work, flock to Lake Chivero in hopes of catching fish, mostly bream, that they can sell for desperately needed income.
