Mordor

Here you can see Reykjavík light pollution from Lake Þingvellir. On an otherwise cloudless night, there was a big cloud hanging over Reykjavík. The lights from the city reflected of it and produce this dramatic looking sky.
The shot pretty much looked like this from the camera. There was only minimal editing done in PS. During my 30 sec exposure I walked down the wooden path with my torch light. The color of the sky was like this viewed with bare eyes.
