imageAs a guest posting, O.K. has put together an intriguing image-ladened paper, Shroud of Turin & Manoppello Image Comparison & 3D analysis: Or the magic of ImageJ.  

Jumping to near the end:

Suppose for a moment that both the Shroud and the Manoppello are authentic relics of Jesus. Being so different, they provide complementary information.  The monochromatic Shroud with it’s 3D properties provides a model Jesus outlook. It is essentially like an old sculpture. It provides information about shape of the object, but no other information like skin, eyes, hair colour.

But what [that] model needs is texture. And Manoppello, if genuine may provide it!

It is wonderfully fun to see how powerful ImageJ can be.
