Current events lead us back to one of the most referenced moments in photography history, Roger Fenton’s Crimean War photographs (March 8 to June 26, 1855). The Library of Congress has a good selection, and large tiff files. Get your archive on.
Beyond the one photograph that is among the most famous ever, there are many more worth looking at. A survey reveals the desolate landscapes that Fenton is famous for, but I was surprised to find a majority are military portraits.
