Why an Atheist Thinks the Shroud of Turin is the Real Deal

Body to Cloth Distance

It could very well be that the image somehow and in some way represented the distance between the cloth and a body. That is a plausible explanation. In fact, that is the only explanation that anyone could come up with at the time. But the data does not prove that. It only demonstrates that the image acts like a height-field.

We have to say that it acts like a height-field and not that it is a height-field in the same way that we need to say that the image acts like a photographic negative, which it most decidedly is not or else it would not act like a height-field.
