Patagonia is mostly known for its famous mountains, but you’ll also find a fair share of stories being told about the notorious weather. And indeed it’s not uncommon to experience four season within one day. Rain, sun and clouds often create unique moods, that we photographers love so much. But what if you’re facing a ridge of high pressure and clear skies?

Well, since we had gone on an eight week trip through Patagonia chances where high that we would have at least a few days with cloudless skies and so I had thought about my options before. Considering the fact that the southern hemisphere offers some of the clearest night skies, it was obvious that I would have to give nighttime photography a try. I was particularly interested in those twilight images of the milky way or a starry sky, still showing detail in the foreground – digital blending of exposures was the way to go.

It was one of those clear days when we reached Parque Nacional los Glaciares. It had been raining during the past days on our way through northern Patagonia and so, although I had been hoping for dramatic skies above Fitz Roy and Cerro Torre, I was quite happy with the sunshine. I knew that it was only a matter of time until the next storm would bring some funky clouds and so I decided to give mountains-in-twilight-with-starry-sky-photography a try in the first night.

Silent Watchers

After a few hours of sleep we left our cosy sleeping bags again and got ready to return to the location we had scouted the evening before. We sneaked out of our hostel and soon we were driving past the last street lamp of the small town El Chaltén continuing into the pitch black night. After a short drive we left the car somewhere along the road and started walking through low bushes in the direction were I had left my tripod after sunset – luckily I had no problems retrieving the location. I clamped my camera back on, set focus, double checked the settings and was good to go.

The final image is a blend of three exposures (see below), showing the whole Fitz Roy Range (including Cerro Torre and of course Fitz Roy in the middle). Once again, the Rio de las Vueltas canyon provided a nice foreground. The lights below the mountains come from the little town El Chaltén and the big “star” you can see a bit right of the center is our neighbouring planet Mars.

3 exposures blended in PS:

  • stars* (ISO 3200, f/4, 30 sec.) *The brightest star in the image is actually not a star but a planet: Mars.
  • mountain range and sky (ISO 100, f/8, 30 sec.)
  • foreground (ISO 100, f/8, 512 sec.)

I used the second exposure as a base and after processing it I added the stars with the help of the “screen” blending mode. The foreground exposure was manually painted in. The flattened result (also flat in contrast) was brought back into LR to add some contrast and punch and for final processing.
