Wim Wenders, whose description as filmmaker, writer, photographer and traveller is still inadequate, has for years carried round an old panoramic camera that has come in handy when the extent or impressive nature of his experience is beyond normal measure. Landscapes stretch into infinity, horizons divide the world into water, earth and sky, streets, whether in Havana, Houston or Berlin draw our gaze to the very depth of civilisation, or to the abyss of horror and destruction as at Ground Zero shortly after September 11, 2001.
