Northern lights and bridge

In September of 2015, the city of Rovaniemi arranged an electrical  emergency drill: all lights in the city were cut off and the power plant  was shut down. I photographed the event for a magazine and waited by  the river for the shut down. I noticed signs of northern lights on the  sky and, as if it had been planned, when the power turned off, the  northern lights turned on. Nature took the attention away from the  emergency drill!
