This was taken at the Scottish National Gallery of Modern Art in Edinburgh as the light was dimming across Charles Jencks’ Landform Ueda. The design was inspired by patterns of nature, the idea of movement in nature, from meteorological effects to chaos theory. Jencks said he ‘wanted to design something which reflected these natural forces’. I didn’t know any of this when I took the photo. I was trying to create a sense of autumn turning to winter, when falling leaves blow across the landscape of the mind. I think this reflects some his ideas about what he wanted to create so I was happy.
