Here are two more views of the Big Horn Sheep group at the Yale Peabody Museum, with a background painting by James Perry Wilson. The top view is the right way round for the diorama and the lower one is mirrored – the correct way round for the original site near Banff in the Canadian Rockies. Again, if anyone recognises the exact location I would be grateful to hear from you.
It is hard to see the curve of the background shell in these views so I will assemble a slightly sideways stereoscopic view to see if that helps, and will post it if it does.
Employ the usual technique to resolve the stereoscopic images – make them small enough so that when you go cross eyed you can register the same sheep over each other when you go cross-eyed. You will see three images as you do this – concentrate on the middle one and try to relax. You can buy glasses (lorgnettes) to help resolve them and these definitely help when the images are larger, but I find I get a better three dimensionality when working without them.
