When the National Galleries of Scotland first approached Andy Goldsworthy about a show to mark his 50th year as an artist, they expected him to focus on one of their outdoor spaces.
Perhaps mingling inside and out, as he did in a show at the Botanic Gardens in Edinburgh in 1990.
Instead, he asked to have the run of one of their largest spaces – the Royal Scottish Academy in the heart of Edinburgh.
It features over 200 works, from photographs, films and sketchbooks dating back to the 1970s to major installations made in response to the neoclassical building.
