The Turin Shroud is the most famous relic in the world. Millions believe that it is the burial cloth of Jesus Christ, bearing his crucified and bloodied image. The cloth is kept in Turin, Italy. It is an enigma, and many say it is a miracle.
WARNING
The truth is that the Shroud has not been sufficiently well examined for a definitive description of the image making method to be derived. Far from being the most studied artefact of all time, all we actually have is a handful of photographs, a few spectroscopic analyses and some sticky tape slides, achieved by pressing tape so weakly onto the cloth that scarcely more than adventitious debris was removed. The fibres adhering were then so thoroughly cleaned in the process of extracting them from the adhesive that it comes as no surprise that almost nothing was discovered on them....
The next of the classic canards is that the image “does not penetrate the threads,” by which it is usually supposed that only the surface fibres – to a depth of two or three – of each thread carry the discolouration of the image, the rest remaining prisitine. The evidence for this is miserably lacking; some say it was discovered by the picking away of surface fibres in 1978, or by simple direct observation.

THE ARGUMENT
There are errors and distortions on the shroud image. Eg the back image is bigger than the front one and there are no side images which you would expect if a body had been wrapped in it. And where there should be distortion there isn't. The man's face for example is too picture-like to have been printed by accident on the cloth from a body. The image contradicts John 19 where a lot of myrrh and aloes which would stain the cloth, would smear the blood and alter it chemically, make the image very indistinct and messed up, were declared to have been used. Worse, there are no traces or marks of any kind consistent with these substances.
The bloodstains are too tidy and you would expect a lot of smearing anyway and there isn't. And why are they positioned on the body image as if it were a painting? They should not be on the cloth as if they were put there by design. You would expect them to be more disorganised and random.
The believers ignore these errors and insist that a dead body lay in the cloth. They rationalise the give-aways but despite using dummies and corpses they are unable to even get the blood images positioned on a similar way as on the cloth. That surely shows no body lay in it. This is worse than if the claim that no science has made an image like it is true. They tell sceptics that unless they can reproduce the Shroud they should not be saying it is forged. But they themselves cannot make a print from a body with the image, an image of any kind such as sweat or paint, and the blood positioned as on the Shroud. That is because the blood did not transfer from anyone but was deliberately plotted.
All you need to make the shroud is to find a way to make an image that sits on top of linen fibres and that is caused by oxidation. 3D is easy - just use two tones and make what is furthest away darker and what is nearest lighter. The image will also look better when a negative image is taken of it. That is not difficult.
The following website shows how to make an image with all the features of the Shroud that shroud believers pretend to find amazing. It can be done by using a linen cloth and putting painted glass over it. The clean side of the glass is put on the cloth. Then it is put out in the sun until a superficial image appears.

There is no reason to think the blood on the cloth is real. The blood might not have been painted on but rubbed on first. Perhaps it was dabbed on with a tiny sponge and then the image was imposed on top of it. This would explain why there is no image beneath the blood. The makers of the Shroud wanted to give the impression that the blood when on before the image which is what you would expect.
People say the cloth is not a painting for it does not look like one. But think of this. The cloth was meant to pass for what came from Jesus' tomb. A portrait of Jesus would give it away as a fake. If it is a painting then it is a painting of blood and sweat. There was more to worry about than blood and sweat. The artist did not paint mud on for it would not stick and brown and black paint would be too artificial.
