One would think that questions of appearance could be cleared up quite neatly by transforming this into a positive. If it is supposed to be an “exact picture of Jesus.” Come on 117 years of research, where is the solid sculpture which would result? Then it can be judged on whether it plausibly meets the scriptural criteria.
I can’t recall if they made a solid sculpture - but my previous link (Face of Jesus) they came up with a full body 3-D image based on the shroud.
I think they DID use a solid model of a generic head to scan to try to recreate how the image was put on the shroud. Turns out a flatbed scanner did the trick. (So not a radial burst of light/energy as I might have suspected if the image was placed during an instant such as the Resurection.)
Don't try to teach thousands of scientists their business, HiTech Redneck.
it's been done multiple times. The data encoded in the Shroud is quasi-3D. . . because it is neither a painting nor a photograph. What it is, is an analog two dimensional terrain map of the three-dminensional body the Shroud covered. . . created by an unknown modality that was completely vertically collimated with zero angular error. The intensity of the image is directly proportional to the cloth's distance from the body. The image density fades to the background color of the linen at the equivalent of about 2.5 centimeters. . . but computer enhancement of the color gradients has been able to extended that by almost triple the distance. Under enhancement, for example, I was informed principal light photographer of 1978's STURP scientific examination of the Shroud, that it can be seen that the Man on the Shroud is circumcised. Since the image carries quasi-3D data, it can do something no photograph or painting can do. . . be translated by a modern computer into a direct 3D model.
