William Henry Fox Talbot revolutionised photography in Britain. Talbot was an expert in many fields including chemistry and optics – the study of light and lenses. He invented the first photographic negative process which became the basis for virtually all photography that followed.
Talbot patented the Calotype process in 1841. In this film, we watch Rob Douglas, who specialises in making calotypes, as he demonstrates the many stages involved in the process.
