The sun – and the position of the Earth relative to it – effectively controls the quality of light illuminating a landscape. Daily and seasonal changes to the angle/strength/amount of sunlight falling on a landscape are driven by astronomical processes, which are very difficult to observe directly with the human eye. Solargraphs however, can record how the Earth’s position relative to the sun changes over the course of a single day, as well as over several days and months.
My solargraphs are an experiment of sorts, designed to investigate the dynamic nature of our landscape. The canisters were left in place for several months, using the most simplistic of technologies to track the skies. At the same time however, the skies were using extremely advanced technologies to track human movements/patterns on the ground. Personally, I find this idea of ‘double surveillance’ rather unsettling.
