De Ruijter hangs his camera on a kite and photographs the landscape of Rotterdam and its environs from the air. For years he has been investigating the possibilities of the bird's-eye perspective and is still able to find new approaches. For example, he experiments with the height at which the kite files. By repeatedly altering this height, he creates parts of the photographs that are in, and out, of focus. These are disorienting abstractions of the Dutch landscape.
