It’s interesting that with all the modern technology, no one has been able to duplicate this “medieval forgery.”
The image is a negative, which becomes positive when viewing a photographic negative. Why on earth would a would be forger create a negative image ? It does seem slightly taller than the average height of Jesus’ time and there is only one piece of cloth when the Bible clearly states two but it basically seems real to me as well.
From my experience, the "medieval forgery" crowd isn't at all familiar with the evidence.
