“Olbinski chases storms . . . capturing lightning, tornadoes and dramatic cloud formations in images that convey the awesome power and beauty of nature.” —International Business Times The storms that cross the Great Plains of North America each spring are some of nature’s most spectacular. They can also be some of the most dangerous. Most people who live in areas susceptible to these storms keep a close eye on the weather reports and take cover or evacuate when one is on the way. Storm chasers keep an even closer eye on the weather data, but for a different reason: they don’t run away when they see a storm approaching, they follow it! Professional photographer and Emmy Award winner, Mike Olbinski has chased storms throughout his native Arizona, as well as even further afield, including Texas, Oklahoma, Kansas, and Colorado. Whether he’s photographing lightning, tornadoes or even cloud formations, his remarkable images are able to convey nature in its most dramatic and impressive forms. With over 100 stunning colour photographs, this book brings together some of Mike’s most breathtaking images from the past five years as he describes his love of the open road and the thrill of capturing the perfect storm on film. “These pictures are truly fascinating; they show just how small we are and how little control we have over the environment and that these storms can pack a wallop. For fans of weather and spectacular photos, this is the book for you.” —San Francisco Book Review (5-star review) “A striking series of breath-taking pictures of nature lashing out from apocalyptic skies.” —Daily Mail Online
