If you've seen sepia images of Native American Indians, you've probably seen Edward Curtis's work.

A new biography, "Short Nights of the Shadow Catcher, The Epic Life and Immortal Photographs of Edward Curtis," pays tribute to the Seattle photographer. KPLU's Erin Hennessey walked around Seattle's Pioneer Square with  author Timothy Egan to see where Curtis took some of his early photos, including his first portrait of an American Indian, Princess Angeline, the last surviving child of Chief Seattle.
