THE SIGNATURE FROM VERSE 70
Highlighted in the centre of the image within the letter 'E' above there is a short string of mostly clear and very neat letters and numbers: PO64PV8E. A fine example of clandestine communications.
There's no secret about my views on the signature nor, for that matter on the real nature of the Verse 70 inscription found in the copy of the Rubaiyat given to Alf Boxall in August 1945 by the nurse who went by the name of JESTYN.
Here are some more images one of which that shows rather faint micro writing:
The stroke through of the letter 'J', a little hard to make out but there are certain markings to be investigated, will probably need to use Infrared to recover these examples, you can clearly see the letters and numbers that follow through on the letter 'E'
Next, here's the image from which the signature came. Its origin was the Adelaide University Facebook group that was formed close to 10 years ago. It was a grayscale image as you can see:
Following the usual method, I first printed this image out at High quality on to bleed proof paper via an inkjet printer. I then used just daylight and took the image with a Samsung S9 smartphone. No need for Infrared with this particular image.
The key is to print the image out at high quality on an inkjet printer, let the printed image dry for about 10 minutes before taking any close up images.
This us what I think you are saying - that you made a high quality print and were able to photograph the hidden code on the print. In photoshop you can enlarge an image as much as you want to - isn't that looking at exactly the same information before it is printed? It also looks as though you have selected a shade of gray that you identify representing the hidden code and increased its saturation to make it easier to see. But why would infa red or ultraviolet light shone on your printed image be able to help reveal the code? I can't see any logical reason for this to be the case - on the original documents yes, but on printed copies, how?
ReplyDeleteThanks for your comment. For the image, as per this post, I used a Samsung S9 mobile phone camera set to macro and was thus able to get a extreme close ups of the signature, what you see is an accurate photograph of the 'Jestyn' signature and in it you should also be able to see the very small characters that are highlighted. The method I used was to print out the image in high quality/fine mode in an inkjet printer. It was printed on bleed proof paper, this effectively stops the ink bleeding or spreading out on the page thus marginally distorting the print out detail. No image manipulation was needed.
ReplyDeleteRegarding infra red, as you probably know there are effectively two types of IR, Far IR and near IR. Far IR is used mostly for thermal imaging and near IR is used in photography. In the latter there are essentially 2 methods one is Fluorescent IR and the other is Reflected IR. With Reflective IR all that you do is to bounce the IR off the surface of the object and photograph it, varying the angles until you get the best result. I have used reflected IR on some images in the past but not on the ones shown here. Similarly I have used UV lighting with varying results, also in the past. The IR source could be a simple clear IR lamp or an IR torch if that's more convenient. I have some images of the set up requirement for both IR methods in a post which I will have to dig out. Thanks again.
