"Catch of the Day" by Thomas Mangelsen captures the moment that a spawning salmon in Alaska, leaping over the rapids, lands right in the jaws of an awaiting brown bear. Produced long before the advent of Photoshop and digital technology, the image is one of the most famous wildlife photographs in modern times. It is counted among Mangelsen's "legacy" images now on a national museum tour across the country. Image courtesy Thomas D. Mangelsen
