The Forgotten 19th-Century Photo Technology That Romanticized America

Taschen has just published a new book called An American Odyssey: Photos from the Detroit Photographic Co., 1888 - 1924, whose 612 pages are crammed with hundreds of Photochroms, a Swiss-invented hybrid of black-and-white photography and stone lithography.
Collectors Weekly interviewed one of the book's co-authors, Sabine Arqué, who explained how this technology found its way to Detroit and ending up giving most Americans their first color glimpse of places like the Grand Canyon, which had been shot decades earlier by the great American photographer William Henry Jackson.
