I'll tell you exactly how this was made and it has been replicated.
In the 1300's the dead body of a random man was made to look like Jesus depicted in the Gospel crucifixion, it was then hung up outside. A cloth shroud was dipped in water mixed with silver nitrate from plants and hung up in a dark room. The wall of the room had a small crystal lens like that of an eyeglass that made a pinhole camera. The image of the body was projected through the lens onto the shroud using the sunlight over several days and it burned the image into the fabric. That's why the image is top-lit, because the sun is high up in the sky. The shroud was then washed and the silver nitrate removed. This is why the image on the shroud is flat and not warped, because it never wrapped a body and is really a primitive photograph on cloth. That had all the technology to do this in that time.
Shit for brains Christians will cope and seethe over this until the end of their days.
