Alpenglow. Very rare seen, but there it was after a very cloudy late afternoon: Alpenglow. I was teaching my Masterclass in the Swiss Alps in october 2021 and at this small lake it didn't seem te be the right conditions for a nice sunset. But suddenly at sunset, the mountain ridge was lit by reflecting sunlight. Alpenglow occurs by direct or indirect reflection of sunlight. The short blue light waves are scattered by the atmosphere and only the red orange long waves will get through, giving it this spectaculair color and effect. A magical moment I will never forget.
