Another vist to the Denge Sound Mirrors today, the last of the summer open days when there is access to the island where three sound mirrors sit. I will sift through the photographs and post a few more tomorrow. The site only opens after two O’clock, when the sun has already passed the reflective surface of the mirrors, so most of my pictures are of the rear surfaces. As the position of the sun changed the texture, facets and board marks conspired with the geometry to provide a lesson in sciagraphy. I will post some examples tomorrow.
