Sure, the Turin Shroud has a 3D-encoded image of a crucified man. So how come the 1532 scorch marks come up in glorious 3D as well?

  "A 3D terrain map projection of the image color intensity. This is one of the most puzzling physical properties of the picture. Produced using a VP-8 Image Analyzer."

The graphic above, plus caption, is taken from the following site:


Has state-of-the art NASA image-analysing technology revealed TOO MUCH?

Reminder: here is the non-analysed image for reference (photographic positive on left, original negative on right). Note the 4 elongated diamond shaped intrusions- not there before the 1532 fire. So why do they map as 3D as well? Miraculous process that defies modern understanding?  Or simply an artefact of too-clever-by-half 20th century computer-aided image processing?

And here's here's another computer-generated reconstruction from a different site.

Notice anything unusual (body proportions, say head v torso?). I am by no means the first to comment on this discrepancy*, nor the suspicion/conclusion that may perhaps form in the mind of the sceptic, namely that the image was faked in two separate parts - the head and then the rest of the body. Shame they were not correctly matched...

* "The body to head ratio on the shroud is nearly 8 to 1. The normal ratio is 6 to 1. This anomaly, omitted from most shroud websites, could indicate that the forger may have sculpted the face, but used a second source, possibly a corpse, for the body. The forger inadvertently made the head too small in relation to the body and introduced this error. A primitive projection system, as the one described above, could have been employed."

The 3D image arises from differences in hue caused by the different intensities of "burn-in" on the image, so that anything else that causes a gradation of hue (such as a burn mark) will produce a "3D effect" in an analysis that estimates depth based on hue. That explains it.

I agree totally. But there is an important consequence of that - namely that any image produce by thermography from a 3D object should produce a 3D terrain map by scanning image density. That would include heated bas-relief, statues etc.

The advantage of thermography, depending on contact and heat conduction, is that it does not require a lens or other imaging system, as would the "cloth at a distance" idea that Jackson has popularised.
