Here is the book description from the publisher, Lark Books:
This beautifully produced guide by Michael Clark is the newest entry in the Digital Masters series, as well as the first book on a fast-growing photographic genre: shooting today's popular extreme outdoor sports, from mountain biking and ice climbing to surfing, kayaking, and more.
Clark is one of the world’s most respected adventure photographers, and he offers sage advice—gained from years of hard-earned experience—on equipment, techniques, and the specific skills required to get in on the action. Learn to capture fast-moving subjects and deal with harsh conditions and horrible weather—even when you’re hanging from ropes and riggings in a squall. Of special interest is the Portraiture and Lifestyle chapter, which covers increasingly in-demand techniques.
