Is it my imagination, or is there one stain (plum coloured) overlaid on another – the latter more the more typical sepia colour of the Shroud image generally, i.e. of body anatomy as distinct from shed blood… Is there a wound under the stain(s)?
Might image inversion (light/dark reversal) reveal more detail? Let’s try inverting the above image first.
Maybe it’s worth taking a look at the much older (1933) Enrie pictures that are also available with Shroud Scope.
Maybe 3D imaging might reveal a nail wound underneath all that “blood”. Time to re-activate my ImageJ software:
Maybe there’s a nail wound lurking round the back. That’s easy enough to investigate. I will rotate the image, while keeping the same settings:
Conclusion thus far (which I am ready to modify in the light of new information): there is no nail wound that I can see under the “blood stain” of that wrist on the Man in the Shroud. If there is no wound, then it is highly questionable whether that is real blood, or at any rate blood that issued from a wound. And I have to say that there is an impression (I shall not put it any stronger than that) that the plum coloured “blood” that seems to overlay older sepia-coloured “blood”(?) makes one wonder if there has not been some touching-up over the centuries. So claims that there is “real blood” on the Shroud, based on tests for haemoglobin, porphyrins, albumin, blood group testing etc have to be regarded with considerable scepticism since we do not know the age of the “blood” that is being tested.
This post is a work in progress, as I am following some comments threads on other sites. I shall be adding further pictures during the day as and when there are lulls in the conversation so to speak.
Postscript: Here’s an image you will not have seen before (with the blue masking to delineate it from surrounding visual clutter):
It’s the Shroud as shown on that Pray Codex, aka Hungarian Pray Manuscript. You can read all about it on my other Shroud site (the one I keep for addressing the trivia of Shroudology).
