Calotype taken by William Henry Fox Talbot (1800-1877). Fox Talbot invented the positive/negative proces for producing photographs between 1835-1839. Any number of prints could be made from the same shot by transferring the negative image on to special paper to make a positive print; Fox Talbot called these prints calotypes.
