Double Exposure: Resurveying the West with Timothy O'Sullivan, America's Most Mysterious War Photographer by Robert Sullivan; 2024. Hardcover.

A personal exploration of the American West and the work of one of America's greatest photographers. Timothy O'Sullivan is America's most famous war photographer. He was also among the first photographers to elevate what was then a trade to the status of fine art. The images of the American West he made after the war, while traveling with the surveys led by Clarence King and George Wheeler, display a prescient awareness of what photography would become; years later, Ansel Adams would declare his work "surrealistic and disturbing."

At the same time, we know very little about O'Sullivan himself. Nor do we know--really know--much more about the landscapes he captured. Robert Sullivan's "Double Exposure" sets off in pursuit of these two enigmas. This book documents the author's own road trip across the West in search of the places, many long forgotten or paved over, that O'Sullivan pictured. It also stages a reckoning with how the changes wrought on the land were already under way in the 1860s and '70s, and how these changes were a continuation of the Civil War by other means.
