This image was taken during a bouldering trip to the Indian Himalayas. I used flashes to capture Bernd as he climbed this nearly 15m highball by the light of headlamps. It was some very delicate climbing and everybody held their breath in the near-freezing night.
Once Bernd was down safely, I made several long exposures for the star trails and spent the rest of the night out alone to get some good options. The final image is a combination of the flash exposure with Bernd climbing, the star trails and lightpainting.
