Site banner: see how a simulated sweat imprint (my wet hand pressed down onto dark fabric) responds magnificently to 3D-rendering computer software (ImageJ) before and after tone-reversal (negative back to positive image). Remind you of anything? Like those supposedly “unique” and “encoded” 3D-properties of the Shroud of Turin body image? For a more realistic aged/yellowed sweat imprint, see the many postings on this site since 2014 obtained with the aid of my Model 10 (imprinting off parts, notably head and hands, of a real body (mine!) onto linen with white wheaten flour, followed by heat-development of the image to generate carbon-based and thus bleachable straw-coloured melanoidins via Maillard reactions between wheat proteins and reducing sugars).
Here’s a comment I left a couple of days ago on Dan Porter’s shroudstory site (my last on that impervious-to-reason site). It flags up my current thinking that the Turin Shroud must have been produced via a TWO STEP process (necessary for fine-tuning the forgers’ objectives of simulating what a 1300 year old sweat/blood imprint might look like on Joseph of Arimathea’s linen, the latter deployed as a temporary makeshift stretcher/body bag* used simply as a dignified means for transferring the crucified Jesus from cross to nearby rock tomb – NOT AS FINAL BURIAL SHROUD).
* See a previous posting on this site, with this and other examples from the artistic record of Joseph of Arimathea’s linen being used as an aid to transport.
Next task (before putting finishing touches on the ‘two-step’ model) is to replace the banner of this site showing one-step scorch technology with some imagery from my recent round of experimentation. It will show stages in the favoured two-step process (imprinting from a human subject or part thereof with a white flour paste, followed by image development using nitric acid (either as vapour or solution).
Update: task completed (though I may fine-tune the images later)
Here’s the previous banner, showing just 10 minutes ago:
Here’s the new banner with a brief description of what each picture shows:
From left: 1. crossed hands on Turin Shroud; 2. a simple one-step imprint of my hand using chocolate spread (posted a while ago to show how fingers can look bony on a contact imprint); 3. first stage in new methodology: coat hand with paste made with white flour and cold water; 4. press linen on to coated hand to capture a negative image, visible (just) on reverse side when linen pulled away; 5. development of the weak primary image using nitric acid vapour (or solution); 6. final developed image of hand after removal from nitric acid, neutralization of acid, washing and drying.
Update (24 May 2015) : here’s a list of postings since April 1st on my sciencebuzz site. It starts with the realization that while H2SO4 did not appear fit-for-purpose in any model for the TS image, another more chemically-reactive strong acid (HNO3) might:

Update: as I say, this blogger is nearing the end of his interest in the TS. So what’s to follow? Answer: it’s nothing to do with fundamental science (more to do with misuse of instrumentation and technology) but it’s still to do with the misapplication of so-called “science”.
A recent experience of driving out of a small village in Ayrshire (Scotland, two days ago) brings it right up to the top of this motoring blogger’s agenda and list of priorities.
The persecution of essentially law-abiding motorists has to stop. It’s become a civil rights issue.
See this recent article in the Mail for growing disquiet re the use of stealth mobile speed cameras, that may or may not be correctly used. Some of the comments especially are worth checking out.
