So let's see....from a logical, scientific point of view....
In order for someone to fake the shroud, this person - living in the late 1300's-early 1400's and using available technology of the time - would have to invent a process to emblazon the image in 3D (the points that touch the body, like the tip of the nose, are more intensely marked than an area recessed from the cloth, like the nape of the neck). He would also have to have access to the ancient Roman whips to get the details right.
This image should be faint on the linen, but be clearly visible hundreds of years later in a photographic negative after photography was invented.
And while the person of that time would use religious paintings for his wound references, he would have to know that the wounds through the hands in all paintings were wrong, and that only the Space of Destot in the wrist could support the weight of the body, and make the wound mark there instead.
And he would have to know to include blood serum on the cloth, which would be invisible to people of his time but glow brightly under ultraviolet light developed much, much later....
WILY-E COYOTE!!! SUPER-GENIUS!!!
Of course, the carbon-14 dating was wrong, since it was taken from a repair patch in the corner of the shroud, The scientists can't be blamed for that, though, because it's not like the church was gonna let them take a chunk out of the middle of the thing to test.
They chose what they thought would be an area least noticeable and objectionable - but as a corner, that was also the area most likely damaged and frayed throughout the centuries. Also, little bits of it had been snipped off in the past as presents from the owner in possession to whatever ruling dignitary he was trying to flatter....
So the carbon-14 dating is basically unreliable - meaning some guy would have to work with even older technology than late 1300's-early 1400's to make it...
Scientifically speaking....
