Image properties
Apologies for the mess I made trying to add a new section. I tried to be faithful to the sources so to be as much precise as possible (as it is a bit technical). It was too faithful... :) I didn't grasp the the Copyright issues. Now I got it.

I still would like to add a new section regarding the image properties without plagiarism, with the same points:

- Superficiality

- Areal Density and its 3-dimensionality

- Image under the bloodstains

The content is the same I already posted but I will rephrase with my own words. I will stick to the content documented in the scientific articles of Fanti, Rogers, Jackson and Adler without external links on photographic image (Is that the POVy part with dubious sources?).

What do you think? Should I post the content here before?

Thanks

 * Yes, please post your proposed content here, with the sources. Thank you :) Wdford (talk) 11:15, 7 October 2022 (UTC)


 * Ok these is a draft of my proposed modification, a chapter "Image properties" after "Image and text analysis". Please let me know what you think. Prismak (talk)
 * === Image properties ===
 * ==== Superficiality ====
 * The Shroud cloth is composed of threads of a nominal diameter of 0.15 mm, woven with fibers of linen with a diameter of about 10-20 µm.
 * The Shroud image is a faint and superficial image caused by a translucent and discontinuous yellow discoloration of the fibers.   In the points where the image is present, the discoloration affects only 2 or 3 fibers on the topmost part of the threads of the cloth.
 * In each fiber, the yellow discoloration penetrates only for 200nm in the external cell layer.
 * Under the crossing threads of the weave, the image is not present.
 * A fiber is not necessarily colored for all its length, but, in the parts where it is, it has the property of being colored all around its cylindrical surface.
 * ==== Areal density and 3d properties ====
 * The image of the Shroud is an areal density image, in the sense that the levels of darkness are not given by variations of the color, which instead is approximately constant all over the image, but by a variation of the number of yellowed fibers per unit area. Therefore, it can be considered a halftone image.  Furthermore, there is no difference in terms of distribution of fiber coloration and maximum densities between the front and the rear of the image.
 * The image density has the property of varying inversely with the distance between the body and the cloth, thus in this way encoding 3-dimensional information of the body, which can be analyzed and visually reproduced with the VP-8 image analyzer.
 * ==== Image under bloodstains ====
 * Regardless the fact that the blood is real or not, the image doesn't seem to be present under the blood stains, when these are removed with a chemical process.
 * According to Alan D. Adler, this would demonstrate that the blood stains have formed before the image, and somehow protected their areas from the image formation process. If we accept this thesis, any proposed mechanism for explaining the image formation should describe a procedure in which the blood is laid down beforehand and then the image is painted or projected later. The blood couldn't have been painted afterward over the image.

 * Thank you, what a wonderful presentation and surprising sourced details (seems some of your references reside at the bottom of this page). The laying down of the "blood" images, riding on top of the cloth but coming before the body image existed, a body image which, although very faint and slight, wraps around each top thread but doesn't go deeper, baffles. How can such a thing be explained in professional scientific terms or in layman's terms? Nice work, thanks again. Randy Kryn (talk) 15:03, 9 October 2022 (UTC)
