Salt Prints at Harvard
Salt prints represent the first negative-to-positive photographic technique. Introduced by Englishman William Henry Fox Talbot in 1839, it is the process from which most nineteenth- and twentieth-century photographic formats were derived. Collections of salt prints found in libraries, archives, and museums at Harvard University include some of the earliest photographic images created, and they represent a seminal chapter in the history of photography. Together, these holdings reveal technological developments in the medium and pioneering uses of photography across the sciences and humanities.
