I didn't take this photo and the next two. I was driving for the 200km journey home, and so I handed the camera to Denise, one of my travelling companions and fellow conference attendees, and explained what 12 of 12 was about and asked her to take some shots of the interesting light effects as we headed down the Midland Highway. She got nicely carried away, so that I ended up with 40 or so photos with varying degrees of blurriness (!), but they captured nicely this part of the day. This photo is of the bridge over the South Esk River at Perth.
