Albumen print. Photograph by Julia Margaret Cameron (1815-1879) of a scene from Alfred Lord Tennyson's 'Idylls of the King'. Cameron's photographic portraits are considered among the finest in the early history of photography. She set up a private studio at her Isle of Wight home at the age of 48, after her daughter gave her a camera, and she became expert at using the collodion wet-plate process. She used friends, servants and neighbours as subjects, including Tennyson and Thomas Carlyle, and the scientists John Herschel and Charles Darwin.
