Tinted daguerreotype taken by Antoine Claudet (1797-1867). Claudet is the best known of the early portrait photographers in Britain. In June 1841, he established the second portrait studio to be opened in London at the Adelaide Gallery off the Strand. Daguerreotypes were images produced as direct positives on sensitised metal plates. The process involved long exposure times and produced only one image.
