What a difference 30 minutes makes! These two shots are taken from the same location just 36 minutes apart. Obviously the sun was setting in the first shot providing some nice color on the buildings. The second shot was after the sun was down ion the “Blue Hour” which is often the best time to capture city lights. At this time of night there is till some light in the sky so the contrast range between the lights is not as great as it is as it gets darker.
