I suppose I should be grateful to "co" in one respect, however,for bringing to my attention the remarkable work of Irene Corgiat with her "electric pyrograph tool", to produce a remarkable likeness of the face on the Shroud.
I have just this minute uploaded her pyrograph into ImageJ sofware to check it out for "encoded 3D information". The result is reported and briefly discussed as a postscript on a recent post on my own site re what I call "scorchography’:
I had forgotten all about Irene Corgiat’s image and the other Leonardo da Vinci theory. And thanks to Colin for doing the ImageJ 3D work shown below:
Do read the article in WWWoodcarver, Volume 7, March/April 2003. 
Once more Da Vinci conspiracy theories about Shroud image production are resurrected, this time not by a kind of protophotography technique but by «pyrography».
My husband’s new upcoming book about the Shroud does focus on this issue and the reader will understand why such claims are just preposterous.
Let’s unveil what he wrote on this subject.
As Dr. Barrie Schwortz pointed out back in 2003, areas of scorched linen fluoresce under U.V. light exposition and Shroud image does not fluoresce under such condition, and besides Irene Corgiat’s scorch image has not encoded 3D data like the Shroud and doesn’t deal with blood stains problem either.
If a microscopic observation would be done on fibers from this scorched image surely the crystalline pattern of cellulose molecules organization would be altered to an amorphous one, which does not happen with Shroud image fibers and colored fibers would not be found side by side with uncolored ones.
The Shroud Image is unique and as Professor Alan Adler once stated «Leonardo can rest in his grave»

Still more promoting of 20th century science, much of it cursory, impressionistic and frankly second-rate, much of it from self-appointed “experts” in “Sindonology” (a pretentious term if ever there was). Are there any real scientists at the Centro Português de Sindonologia doing original research, instead of parroting the same old mantras, blithely ignoring – or ignorant of – any and all counter-arguments?
It would help if Maria da Glória were to enlist the aid of some real scientists at her Institute, assuming there are any, to evaluate and comment on their and others’ ‘trump card’ namely the highly questionable fluorescence issue.
They could start by defining the precise chemical structures of the fluorochromes in linen scorched under different experimental conditions, the likelihood or otherwise of those fluorochromes being of sufficient chemical stability to go on fluorescing over centuries of exposure to air, light, smoke and other pollutants etc etc.
Yes, I know the 1532 scorch marks still fluoresce, but they are supposed to have been produced in a closed reliquary under conditions of limited oxygen having been exposed to an intense fire generating temperatures (we are told) high enough to melt silver (962 degrees Celsius). The 1532 scorching could involve entirely different pathways of pyrolysis, with different end products. One cannot equate aerobic and non-aerobic pyrolysis, or low and high temperature pyrolysis. I know from my own research that the faintest of scorches can be bleached with 6% hydrogen peroxide, whereas more intense ones cannot, implying a sequence of chemical events at the molecular level, not a single simplistic either/or response.
More science please, and less parroting of tired old mantras.
Less dictating and talking at people and more independent review of your claims, please.
Collin,
I do agree with you, the Turin Shroud image doesn’t involve any supernatural image formation process. It is to be more seriously studied/researched in conjunction with (at least) one possible heating source.
However, how long do you SERIOUSLY think Irene Corgiat’s pyrographic (or even any of your own much awaited “kausonographic”) pseudo Shroud face Image could fool any medical examiner who would professionally proceed to its “autopsy?
Corrections: “could fool any medical examiner that would professionally proceed with is “autopsy”?”
That is the question…
My advice to any hospital pathologist minded to base an autopsy on a faint image on linen, centuries old, of unknown provenance, would be to get a CT scan done as soon as possible on his own cranium. He should not be surprised to learn there is a large fluid-filled cavity in his brain where previously there was grey matter…
This is actually funny.
By means of his thermostenciling technique, could then Mr Scorchscientist for Easter, lightly bake/cook us a couple of mummified skeletons in the manner of the Turin Shroud so that we can check if they can stand TOO the double test of a medical examination and blood pattern analysis?
My advice to any kitchen scorchscientist minded to reproduce such a faint image on linen, centuries old whether of known or unknown provenance, would be to get a mummy toaster as soon as possible. He should not be surprised to learn there is none currently available on the market
The moral is, no matter how light/dark a kitchen scorchscientist’s matter may be, what matters here is substance.

I’m not a scientist and neither is my husband who is a medical doctor but there are some members of Centro Português de Sindonoogia from several fields of science who agree with scientific information conveyed by S.T.U.R.P. investigators and others.
When it comes to the Shroud, real scientific information is gotten mainly from those who had access to direct study of the Shroud and gathered samples for off-site studies and later published their findings on peer reviewed scientific journals.
S.T.U.R.P. studies, Professor Raymond Rogers and Professor Adler’s studies are considered crap by Dr.Colinsberry, to him only does matter his own opinion, and that’s truly outrageous to honest Shroud scholars.
Shroud science should be based on facts and not guesses.
The late Dr. Walter McCrone is on the skeptic side but nevertheless his conclusions disagree from Dr. Colinsberry claims of the image on the Shroud being a scorch.
Dr. Colinsberry stated that scientific investigation should be done so here goes a challenge for him.
Dr. Colinsberry as a great scientist he claims to be should be able to reproduce by his scorch technique a life size image of the Shroud that would fit ALL characteristics and properties of the Shroud image namely optical, microscopical , physical and chemical and which would deal with the blood marks being impressed on the cloth before the image.
And why not present this hypothetical work at «Scientific Conference on the Holy Shroud» which will be held at Valencia University-Spain next April 28-29-30 ?
I guess the comitee is still accepting papers just search http://www.linteum.com
