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).
Note the title refers to the two-fold aka double body image on the Turin Shroud. Up until now this blogger/retired scientist has been content to model either the frontal OR the dorsal surface, using his latest white flour imprinting technology, but not both together. However he was challenged yesterday to produce both images on the same sheet, with a suggestion that it might be difficult to get the two correctly aligned.
Well, one is not given to passing up a challenge, so out came the usual ingredients and materials this morning – plain white flour, olive oil, linen etc. But what to use as template? It would have been more dignified to use the brass crucifix, but there’s a problem with those outstretched arm still in crucifixion mode if wishing to model the head-to-head frontal v dorsal alignment. So it was back I’m afraid to my plastic Galaxy Warrior, the same one whose imprints adorn the banner of this blog. His arms don’t cross the groin region, for full TS authenticity, but do park neatly at his sides.
Let’s cut to the chase: here’s the end-result of imprinting off the Galaxy Warrior to get the iconic two-fold image of the Turin Shroud.
Here’s the double-body imprint after tone-inversion and 3D-rendering in ImageJ:
That’s enough for now. Comments and discussion relevant to the posting are invited. Photographs are available of each step in the imprinting process should anyone be interested.
Postscript: here’s a composite collection, using the above images:
Note the amazingly close correspondence between the 3D-rendered flour imprint and the 3D figurine from which it was derived.!
