After sunset photographers can go to bed, one could think. But not yet. The first half an hour (or longer, depending on the latitude) after sunset, there is still enough light to take pictures. The warm colours produced by the low sun are gone, and turned into a cold blue light. Photographers call this the blue hour. Here a picture taken in the same spot as the one in my previous post. The landscape looks completely different now, but it still has its charm.
