You mean the medieval artist who painted with radiant energy? There is no pigment on the Shroud. At all. Of any kind. Anywhere on the Shroud. Repeating: there is no pigment on the Shroud. Is this too confusing?
not to mention the folds of sheet that wrapped around the face which can produce a negative 3d image,
It can?
if there was any un orthodox way of placing a sheet on anyone other than laying down on the face, no matter who it was please describe that technique, gravity works on everyone the same way.
Take a piece of paper towel and wrap it around a doll's head. Mark with a pencil the two ears and the two eyes. Now unfold the paper towel. The two eyes will be in the proper position but the sides of the head will also be facing forward. On the left you will see the left side of the head with the ear in the center, in the center you will have the face and on the right you will have the right side of the head with the ear in the center. The "face" will be three times wider than normal. This experiment has been done many times, and this is the constant result.
Now imagine a sheet placed over a body which emits a burst of energy. The sheet would be "scorched" in proportion to its distance from the body. Highpoints, like the nose, would produce a more intense image, thus producing an embedded 3D topographic image. This theory conforms perfectly with the actual image on the Shroud. This is why most scientists who have studied the Shroud believe that image on the Shroud originated in this way.
No different than taking a photo, which produces a negetive image
The concept of a negative image didn't exist until the 1800's, 700 years after the time when this image was allegedly forged.
This image would not contain an embedded 3D topographic map of a human body. - a 2 dimensional photo doesn't either.
Which is what makes the image all the more remarkable. I am a 3D computer artist, so I know how this works. If you import a grayscale image into a 3D program as a terrain map, the lightest areas become high points and the darkest areas become valleys. When the image was run through a NASA terrain analyzer in the mid '70s a virtual 3D image of a man resulted. How could a medeival forger do this?
You have just explained the shroud away...It had to be painted! It could not have been on any face then.
