NIGHT LIGHTS is a time-based study of urban light pollution that enters into the rooms in which the artist sleeps while traveling. With exposures ranging from 30 min to 7 hours, her large format color negatives become receptacles for the ambient city light that lands on the walls and ceilings of her lodgings in New York, Hong Kong, India and Los Angeles. Both the artist’s experience of these private light shows, as well as the hours-long obfuscation of the artist's own bio rhythms become embedded in the emulsion of her negatives, making this one of Irving’s most intimate projects.
