It occurs to me that Nathan Wilson’s famous “Shadow” satisfies all but one of the image characteristics of the The Valencia Shroud Enigma Challenge. That one shortcoming is easy to remedy.
The “Shadow” is certainly a molecular change confined to the outermost few hundred nanometers of the fiber, well within the primary cell wall. The “Shadow” is not visible when viewed with transmitted light. Image intensity does correlate to imagined cloth-to-body distances. There is no side-of-body imaging. Image resolution matches that of the Turin cloth. And as with the Turin cloth there are no outlines. Nor is there any notion of directionality. Of course, the “Shadow” is very much a photographic-like negative.
There is only the matter of there being no proof of no image below a bloodstain to make the “shadow” fully compliant with the challenge. It is a problem only because no blood was used on the original “Shadow”. That can be corrected and a new image can be prepared in a week’s time.
Please provide the UPS mailing address of the judging panel. To whom should I send wire transfer instructions.
