@lololulu19 Many distortions - remember, story is that cloth was wrapped, draped or folded on body.
It's not photography from 3 meters above, as we would understand it.
Doublings or bends in the cloth, could make distortions as weird super-3D negative image got radiated into cloth - somehow.
Another thing they found - other studies:
Blood specks have chemical markers of extreme stress - consistent with torture & crucifixion.
No medieval forger would think, "Oh I'd better use blood from real torture victim because in 21st century, chemistry science might get good enough to know."
Argue who it is - but, if forgery, explain how. Or if real, explain how.
Point is: it's inexplicable.
Even if you say "technology did it" - OK - whose technology? And how would it be around, in first century AD? Aliens? Wanna go there? Really?
Different thing - Pyramids got a possible solution, recently - Big stone blocks were floated up waterways.
