If you happen to be in Barcelona between 22 February and 19 May 2013, make sure you visit the Caixa Forum. The entrance is free. I saw the video below for the first time there and I thought, still I think, it is great. The video is an ode to David Octavius Hill and Robert Adamson, who photographed Elizabeth Rigby in 1874, by Maisie Broadhead.
