Photographed in New York, Hong Kong, Bangalore, and Los Angeles, these long-exposure images—some up to seven hours—transform ceilings and walls into luminous records of insomnia, jet lag, and circadian disruption. Irving’s film becomes a vessel not just for light, but for time: the time spent adjusting to a strange room, the time hovering between sleep and wakefulness, and the deep physiological effects of a world that never goes dark.
