Quantified Landscape 3

What technique did the photographer use to create this image? In his series Quantified Landscape, the Swiss photographer Florian Amoser bridges the gap between two extremes: wild nature on the one hand, and data-driven technology on the other. Amoser is known for his conceptual approach to photography, and in this series, he creates works that combine landscape photography with data visualisation and manipulation, resulting in a new perspective on nature. Think back to your last experience of nature. Was that truly, physically, in the open air? Or was it mediated by a screen? Amoser took this photograph with an analogue camera. Inside underground caves he traced the outline of the rock wall using a laser. While the laser drew contour lines on the walls, the camera recorded the emerging line drawing for hours on end. The result catches the movements of the laser in a single photograph.
