The Labyrinth or ‘los colorados’ (the colours) is a fascinating part of the Puna landscape in Argentina. I have been promising myself that I should dedicate a week or so to this place alone. And I have made plans to do so several times. But it’s an extremely difficult place to photograph well.

The location does not suit soft light as it really requires shadows to help set out and define the contours of the terrain. When the sun goes down, I often feel that I’m waiting for the light to get better, but once it flattens down to an extremely soft light, the contrasts that are required to set the scene up just aren’t there any more.
