On a recent visit to the Tate Modern in London I spent some time in the Olafur Eliasson installation in the new Tanks gallery. The darkness was punctured by the changing light of the huge installations which silhouetted everyone that walked in to them. It was busy, so I had to wait patiently for just a single person to walk in. The image has been processed to accentuate the scale of the tanks and the mood the installations created in the space, as I wanted to create a filmic, sci-fi look.
