During the late 1850s the beginning of widespread use of the negative-positive process, which allowed the efficient production of a large number of prints from a single negative, marked the end of the daguerrean era in America. Many commercial photographers whose business had been built on the popularity of the daguerreotype portrait converted their darkrooms to accommodate a variety of new photographic processes. In many places, however, studios still employed painters to hand-color the finished image, as they had done with daguerreotypes. Photographers increasingly took advantage of the rich tonality and matte surface offered by the salted-paper process. Prepared by coating the paper with a solution of sodium chloride (common table salt) and then brushing it with a solution of silver nitrate, salted paper prints range in color from warm chocolate brown to slate gray.
