UNITED KINGDOM - OCTOBER 23: Portrait of Julia Jackson (1846-1895), mother of writer Virginia Woolf and artist Vanessa Bell, by Julia Margaret Cameron (1815-1879). 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 the scientists John Herschel and Charles Darwin, and the poet Alfred Tennyson. (Photo by SSPL/Getty Images)
