This was the scene we were treated to each evening at the Atacama Lodge in Chile. Quite an amazing skyline, with 5,900-metre-high Licancabur Volcano, here at sunset.
The sky colour comes from a phenomenon known as the Belt of Venus, a magenta/pinkish glow from sunlight lighting up the upper atmosphere after the Sun has set for us on the ground. The dark blue rimming the horizon is the rising shadow of the Earth.
I have punched up the colour saturation here to bring out the colours, but not so much as to be faked — the colours are real!
This is a shot with the 50mm lens and Canon 7D camera, taken on one of the nights we had dinner back at the lodge, in this case with a group of Québec amateur astronomers also here this week who were great observing friends on the field.
