Using the Canon 5d3 I shot a timelapse of long exposures. You could hardly see this building with your eye. It was lit by one small amber light. You can see the occasional additional light from traffic. This was shot at 12 midnight in a small country town, New Norcia, Western Australia.
RAW files, 50mm 1.2, 13 sec exposure at F8, ISO 6400. Timer interval 10 secs.
