Alexandre EstrelaInversao Polar, 2011
16 mm film, coleur, silent, loopThe Greek word 'archeiropoietos' desginates an image which is formed without human intervention. Every year, the backyard of a building in Lisbon witnesses a peculiar phenomenon, in which sunbeams pass through a small hole in a tree, projecting a circle in the façade of the nearest building.
The resulting effect is not a reflection, but rather a spontaneous image formed by the intervention of a natural 'camera obscura'. This particular setting offers the ideal conditions for the sun to project an image of itself. Like all images produced by means of a 'camera obscura', this too is an inverted image. In 'Inversao polar' [Polar Inversion], this phenomenon was captured in film and reproduced so that the image of the sun is cycliclally inverted, this restoring its original position.
