Salt paper print by British pioneer of photography, Reverend Calvert Jones (1802-1877). Jones first received instruction in photography from William Henry Fox Talbot (1800-1877) in 1845. Talbot had invented the first negative/positive process for producing photographs between 1835-1839, patenting it as the calotype process in 1841. Jones was a notable photographer in his own right, but also collaborated with Talbot for several years.
