At night all cats are grey. But that doesn't apply near the Arctic Circle, when bright northern lights bathe everything in a green glow. You can see this with your own eyes.

It was the same on my trip to Iceland in October 2015. I mainly spent my time there at Hvalfjörður Fjord . Here in the southwest of the island is the influence of Golfstroms strong. Temperatures often remained near zero degrees. The humidity was high and I had to struggle with fogged up lenses. The clouds were constant companions and, together with the northern lights, created exciting impressions in the sky. The photos reproduce the colors more intensely than I perceived them. However, the direct experience of the star-studded northern sky more than made up for the reduced color sensitivity of my unaided eyes.
