And I'm sorry, but photography seems to be well out of your area of expertise.
To wit:
1. It's tempera, not photography, that requires a hard, flat surface. You can print a photograph on anything you can coat with photo emulsion: glass, cloth, rocks, coffee cups, paper, etc.
2. See my comments to Marrah G below. A pinhole without a lens not only can be but has been used to focus an image this large. The crucial element of focusing a pinhol box is to get the correct distance between subject and film--or cloth, in this case.
3. I never claimed that the image was created in Lirey. That is where it surfaced, in the possession of a Crusader's family. Optical science was considerably more advanced in Byzantium and the Muslim East than in western Europe in the 13th and 14th centuries. My guess is that the image was made in Constantinople, or possibly in Damascus or Cairo.
4. The 500 year gap is a problem. But I prefer this problem to the problem that the rubbing image bears only a crude and superficial resemblance to the image on the shroud.
