There is a fascinating bit of reasoning going on in the mind of Colin Berry. You need to click into Does the Man on the Turin Shroud really have a beard and moustache? (Or is the image an ‘impactogram’?).
“I’ve been there and read that posting,” I hear you say. Me too. That is why I missed an interesting bit of analysis until a reader pointed it out in an email. Colin has a strange way of adding to posts already dispatched to the servers in the clouds as new thoughts come to him. In the meantime, I’ve read his posting and the search engines, typically, have done whatever it is they do.
— should have been a posting in its own right. But then again, who am I to tell Colin how to post. So go back to his blog and this time scroll down to the new addition. Here is enough to entice you to do so:
The picture on the right is a Durante 2002 "positive" from Shroud Scope.The one on the left is the much earlier (1931) Enrie black/white negative, but I’ve edited it to make it roughly comparable with the Durante image, first by reversing it, left/right, and then "inverting" the tones in ImageJ.
[ . . . ]
Why reiterate the distinction between the two types of -graph in the context of the chest region? Because there are no obvious reasons for expecting a large difference in image intensity in a photograph that shows chest and upper (solar plexus) abdomen in the same field of view. Why are we seeing it – especially in the contrasty Enrie pictures? Because the elevated, rigid chest region, whether of a real person or an effigy thereof impacts more on linen, suitably supported, than does the contiguous softer, lower lying area.
. . . It’s everything to do with an unyielding structure called the upper rib cage, and its impact qualities when pressed against linen.
The next region to consider is the groin with those crossed hands. I believe it’s providing strong clues as to the mechanism of imaging, and no, it’s not dependent on any kind of radiation. Clue: look at the region where one hand overlaps the other.
More later (maybe not today)
Hopefully, more later will be a new posting so it gets noticed and I will get a bell tone on my iPhone from Google telling me Colin has something new up. Then I could focus on the right things like what Colin has to say which is really interesting and I think meaningful in the greater context of image formation theory.
Sorry Dan. No disrespect, but I don’t blog to provide a news aggregation site such as yours with a never-ending flow of new content (and I frankly never cease to be amazed that you flag up my postings within minutes of my hitting the Publish key).
I explained a while ago that I am reporting a long-term ongoing research project, started some 30 months ago, in real time, with a blow-by-blow account. It’s really for me, and me alone, to decide when to start a new posting, or when to add riders to the current one.
Reminder: blog is short for web log. Regard my blog as one might a ship’s log, that ship having just entered some choppy waters, and requiring a cautious hand on the tiller (thus my writing in short instalments).
Some here do not even seem to have spared a thought for why hair on the TS fails to show strandedness, I’ve just this minute inserted an image of Bob Geldof, chosen for his TS-like hair, to make absolutely certain folk know what I am referring to.
Word of advice Dan. If you dislike finding additions when you return to my posts, then wait until I post a new one, then do your piece on the previous one. It’s then unlikely to be further edited.
Yahoo and Facebook are news aggregators (although Facebook as we see is a bit tweaked in that regard). Unlike them I read material and evaluate it. Often I comment on it. I am not a news aggregator. And you are not news. You are completely focused on the by-my-way part of my posting. Lighten up. I was, admittedly in an off-handed way, saying that your content was too significant to be missed, as it was likely to be because of the way you posted it. Okay, a bit more directly: GREAT STUFF (excuse me for shouting). Do it however you want. It is still great stuff. As for your word of advice: as they say in The Bronx, fuhgeddaboudit.
A real corpse, this is a U-Turn for Colin Berry.
Next one, not a scorch but a chemical reaction ? :)
Next step soon, CB will see with his own awe-stricken enlarged eyes, the TS embedded in pieces in the HP Ms folio 28r lower section ink drawing and his quicklimestoned mummy laden ship sink for good in ten thousand thundering typhoons off the coast of Brittany (France).
No one faking the Shroud would have a clean-shaven Jesus, and the hasid-like Jesus would have both moustache and beard.
What to say ?

The current result of this long-time research: the TS image is a scorch, But I do not know how it was made. And It is not a photograph (we knew that).
Hot template? But ‘However, I’m as conscious as the next man of the practical difficulties of imprinting successfully off a life-size effigy. Mistakes would be costly, given the price of quality linen,’
Price? Is it really the problem?
In my opinion, the so-called practical difficulties of imprinting using a hot template are in fact impossibilities.See my PDFs:

Look at my PDF1.in which I wrote: ‘Another interesting fact comes from the observation of the lack of visible color on the backside of the lateral bands of sample 3 (Fig.2, sample 3B) even if the corresponding areas on the front (heated) side are STRONGLY scorched. This is explained by the fact that I immediately removed the hot plate (contact time less than one second). A superficial discoloration at fabric level can be obtained even at high temperature with a very short contact time because the diffusivity of the cellulose of linen is very low’.
In any case, lack of color on the reverse side does not mean “superficial” in the sense of the superficiality of the TS image as shown in PDF 2.
After many hours of experiments,I know that the Ts image is not a scorch.
Because heating (alone):
1) can not give a discoloration as superficial as the TS image (only 1-3 surface fibers)
DO YOU REALIZE THE EXTREME SUPERFICIALITY OF THE TS IMAGE ?
2) can not explain the half-tone effect.
Then Colin tried the quicklime hypothesis ???? And …
And now the “impactograph” (or impactogram).
I do not understand CB’s way of working, jumping from one subject to another..
I definitely prefer PDFs ….
“DO YOU REALIZE THE EXTREME SUPERFICIALITY OF THE TS IMAGE ?
There’s no need to shout, Thibault.
Unlike you, I have hands-on experience with scorching at the cellular and subcellular level. I refer to the experiments I did with (thoroughly) dried onion epidermis – just one cell thick – and little more than a pair of primary cell walls, each approx 200nm in thickness, comparable to alleged TS image thickness. That single layer gave complete protection to underlying linen, while itself becoming extensively scorched.
The factor that is overlooked in so much ill-informed comment about template scorching is the endothermic nature of scorching reactions, which withdraws a lot of heat from the template at each pressing. That’ss why scorching by direct contact can be so superficial.
Your nitpicking response to my onion experiments? To unhelpfully suggest I had not fully-dried material (I had).
You nitpick, Thibault. You should try being more constructive and cease this sniping by PDF (the latter full of ex cathedra pronouncements, inviting no comments).
Sorry Colin, I do not consider your ‘dried onion epidermis’ experiment relevant.
There are too many differences with direct experiments on linen.
Do you want me to list the differences ?
In fact there is absolutely no relationship between your experiment and the fact that you are supposed to demonstrate, i.e. it is possible to scorch only 2-3 fibers at the surface of a linen sheet with a hot template by direct contact.
Do you not consider it extraordinary that gossamer-thin onion epidermis so thin that if takes ages to reach the floor when released from a height, gives complete protection of underlying linen from a hot metal template, the latter hot enough to scorch unprotected linen, and which in fact scorched the overlying epidermis a deep red-brown colour? I do, or rather did.
So list the differences if you wish, Thibaullt, if you think they are important. But don’t forget to mention the fact that dried onion epidermis, just one cell thick, consists of little more than two primary cell walls, lacking the much thicker, robust secondary cell wall of plant fibres like flax bast cells (“linen fibres”). .Those tough fibres are primarily thick secondary cell walls. So how come a pair of skinny primary cell walls is somehow able to block the passage of heat, sufficient to protect what’s underneath from scorching, while the vastly thicker flax cell wall cannot.
Sure you can list differences, Thibault. Why have you not done so already? But as I say, there’s one obvious difference that one might have expected to make onion epidermis ineffective – the absence of a secondary cell wall – but which did not. What’s more, I’ve provided a scientific explanation: namely that scorching, i.e. chemical dehydration of linen carbohydrates, is highly endothermic, causing rapid cooling of the template, and making the process highly superficial at the cellular level.
In short, the odds were stacked against my little experiment working. Yet it worked – in spite of everything, yet all you can do is nitpick on matters of inconsequential detail, overlooking or ignoring the bigger picture.
Yawn.
Written any good pdfs lately?
PS to Dan – thanks for acceding to my request to delete my previous comments re an over-hasty report of this morning’s quicklime experiment.
Thibault, scorch is dead, Colin just wants to keep playing, whatever inconsistencies.
There are a lot of practical difficulties about producing a scorch image by heating a six-foot long hot metal template, but that doesn’t mean the scorch theory is dead; far from it. If the image on the shroud is nothing but degraded cellulose, then it chemically very much resembles a scorch, and the problem is the physics, be it Yannick’s mysterious low temperature radiation, Colin’s new quicklime ideas, or painting with a soldering iron, as has recently been done by Hugh Duncan. As for the superficiality, I don’t think people realise how dense the Shroud is. It is almost twice the density of a bed-sheet, for example. This in itself is enough to prevent much that happens on one side from penetrating to the other.
Yes, all the ‘scorch’ variations explored so far are riddled with difficulties. But then, so are all the ‘radiation from a dead body’ ideas, and even the ‘completely new physics unknown to man’ ideas. Fascinating, isn’t it?
I am curious to see the image of that
“first thermochemical image (of sorts) using a horse brass, quicklime, linen and water”…
Despite your previous behavior (a bit grumpy) I wish:
Good party!

But next time do not forget to use the iron oxides!
I am curious to see the final effects (from CaO + FeOx).
What might happen with that mixture (…on wet linen)?

Oxidative damages (and experiments) :
Anyway, why do not you tell us anything about the oxycelluloses?
I have read that oxycarmin dyes oxycelluloses dark blue to dark violet …
What is the best sistem to detect the presence of oxycelluloses on your experiments?
Perhaps these tests (now) are a bit ‘too refined?
When you can run those tests (about oxycelluloses detection)?

I expect a second rebuff …
