I shot this when my wife and I took on of my newly graduated photo students with us to Paris. My student's camera had broken so I let her use my Canon 5D And I shot this with a Panasonic bridge camera (I don't remember what model). I set the camera on a chair in the nave and shot by the little light available from the stained glass windows. The exposure was f/4 at 1/30 second at an ISO of 1600. I shot in B&W mode.
