"Drawing with Light: Paper Negatives, 1842–1864"

A fascinating glimpse into the early history of photography, "Drawing with Light" revisits an important development—the calotype process, which allowed multiple prints to be struck from a paper negative. This was a tremendous leap beyond the existing daguerreotype technology that produced only one-off images. On view are paper negatives by William Henry Fox Talbot, inventor of the calotype, and other pioneers of the form, including Charles Nègre, Dr. John Murray, Frédéric Flachéron and Louis-Rémy Robert.
