Guido Baselgia - light fall : photographs, 2006-2014

Celestial mechanics have fascinated mankind in all known cultures.

Many artists throughout history have been captivated by the spectacle we observe above us day and night.

Swiss photographer Guido Baselgia has expanded the focus of his work on the sky, with the stellar and solar movements and phenomena as we see them from earth. In his most recent work Light Fall, Baselgia makes traceable the trajectory of celestial bodies invisible to the human eye and shows astounding occurrences of light and shadow.

Taken in Norway, the Tierra del Fuego archipelago in Argentina, in Ecuador, and the Swiss Alps, the images visualise the geometry of astrodynamics and celestial mechanics.

His photography also captures the phenomenon of umbra, planet earth's shadow thrown into space. The new book Guido Baselgia - Light Fall features 80 stunning tritone plates.

Complemented with essays by German scholar Andrea Gnam and Swiss photography critic Nadine Olonetzky, they offer a window into the light phenomena that leave us awestruck today as much as they did our ancestors.
