Photography, at first dedicated to reveal the world, may also flourish landscapes without recurring to light. Cao Guimarães' photos, made with cameras deprived of means and sensibility, are opaque images. The dense, almost tactile scenes of damaged walls, eroded by time, interact with the Mill's concrete walls and its ground covered with dump and moss. Strange textures' overlay, where the gigantic images seem to create unfoldments of the time and the space experienced there.
