Desert Air is the first comprehensive photographic book on all of the world's extreme deserts (defined for the purposes of this book as those that receive no ore than 4 inches of precipitation per year), the most remote and inhospitable places on earth. It is also a visual adventure story by one of the world's top expedition photographers who has spent the last 15 years on this epic body of work. The stunning and surreally beautiful photographs are enriched with stories from his adventures in the world's most difficult places: smuggling his aircraft into Libya, getting arrested fro spying in Iran, crashing into a tree in Western China, and into the ocean off the coast of Mexico. The book is a comprehensive exploration of virtually every dune field and patch of barren ground that add up to the last great class of wilderness left on our planet. To visualize these remote places in a unique way, Steinmetz learned how to fly the world's lightest and slowest aircraft, a motorized paraglider. This experimental foot-launched aircraft consists of a backpack motor and a parachute-style wing that lets him fly low and slow, to take pictures of places that have never been seen before. Together, these extraordinary places are like a disparate family of co-evolved landscapes each similar but uniquely beautiful.
