A project blog by Larry Schaaf is dedicated to Harold White's experiments into chemically reviving the latent image in some of Talbot's original photographs and negatives. A label pasted, verso, gives an explanation of White's methodology for the chemical re-development of the original negative and cites an entry in Talbot's notebook on reviving the latent image.
