A test of historical photos of the stone arch bridge in Minneapolis. Not very synthy at all, but good for zoom browsing.
Results: For the 4 sets of photos which were synthed, the 3d perspective succeeds. It's very cool.

For the rest of the photos which didn't synth, it would take higher resolution scans from the artifacts. Possibly a History Center artistic collaboration.
