Hi Bryan
I don't know of any such photos. A 10x magnification might be enough, but 20x is what John uses. (Assuming some adequately high resolution imaging at the eyepiece end!)
Once you've photographed, you need to stitch. Success in stitching will depend on how good your images are, for planarity, focus, and evenness of illumination.
When you have your huge image, you now need to capture polygons. I think people have used various software, including the Gimp, and Photoshop, and other photo-editing software. No-one has had much success with automatic feature recognition - it's always manual.
See for example
http://www.qmtpro.com/~nes/chipimages/ for some info. There's a program called degate which is supposed to help with structured/repetitive layouts but I don't think I've seen results from it. See
