Spent a long time today at the wonderful ‘Landmark: The Fields of Photography’ show, put on by the Positive View Foundation at Somerset House. The show takes a broad view of contemporary and recent landscape photography, and is themed Sublime, Pastoral, Witness, Landmark, Scar, Control, Datum, Delusion, Hallucination, and Reverie. The types of photography are very varied, as are the printing techniques – one piece being three-dimensional, another a mosaic of images from Flickr. The show takes the whole of the East Wing, but doesn’t feel too big, and is worth visiting, even if photography isn’t your preferred visual art. (Open till 28 April 2013, no cost to enter.)
