All STARS are enhanced in Photoshop. The stars are actually there, but fainter in the original image.
Magic colors struck earth on october 25, 2011. This is Aurora Borealis / North Light at the most spectacular.
This photo was taken just outside the city of Tromsø, Norway.
I had an amazing photo trip this evening/night. After weeks with poor weather conditions, I didn't have much hope for clear sky tonight, either. But just before midnight it started to clear up. And what a display I withnessed!
I've never seen red and purple Auroras with the naked eye before tonight. In some of the photos I even got red reflections in the sea.
