Just been re-reading about this, and it turns out I posted the below upthread on 17 March 2014: At the risk of sounding trite, don't give up on this one! We may not have the technology now, but perhaps one day it will be possible to 'read' the image on the film without unrolling it. From the Wikipedia page on the Herculaneum papyri, it seems that techniques are being developed to read these badly-charred papyri without opening them first: 'In 2009, two intact Herculaneum papyri housed in the collections of the Institute de France in Paris were imaged using x-ray micro-computed tomography (micro-CT)... The internal structure of the rolls was revealed to be extremely compact and convoluted, defeating the automatic unwrapping computer algorithms that the team had developed. Manual examination of small segments of the internal structure of the rolls proved more successful, revealing the individual fibres of the papyrus. Unfortunately, no ink was visible on any of the small samples imaged, probably because carbon-based black inks had been used in antiquity, which have a much lower contrast to the blackened papyrus than inks with metallic bases. Progress with this promising technique thus most likely depends on the development of higher resolution micro-CT scanners so that computer algorithms can be created that will unwrap rolls automatically. A method is also needed to increase the contrast between the carbon-based ink and the charred papyrus.' It's quite a jump from a papyrus to a film, I know. But who knows. Maybe in the future we'll have phones with cameras and driverless cars... ;-) Hey, Morecambe and Wise fans, you don't have to thank me! *bows, takes applause* *realises a load of other people actually put in the legwork* *shuffles away*

I received a message from Charles Norton at the time to ask about the home recorded audio.

Plus in January that year if that idea had already been had it certainly wasn't public, and even Paul V was claiming defeat at the time.

There is a lot to be said about announcing recoveries only when they are ready. Think of the enormous amount of "are we there yet" that would otherwise have to be faced - or the madness surrounding DW.

My point being that cjones can't be mocked for coming up with the idea of CT scanning if, at the time, it hadn't been announced as the next avenue of exploration, whereas instead of delighting in great minds thinking alike, you seemed to delight in bursting his bubble to the tune of "you should have known since January they were already planning to do that", which is how it came across; as if he should have known.

Yes, that is exactly what I said. Obviously I have it in for cjones, who offended me in a previous life.

If you think I've forgotten about how you jibbed me playing three-card monte in nineteenth-century Lisbon, you're sadly mistaken. Not that one, the other one. And don't even get me started about Naseby.

And don't even get me started about Naseby. Oh right and that wasn't completely fair after what you pulled in Memphis (Egypt) 3500 BC...? (Don't forget that dung beetles were considered to be holy beings back then!)

I noticed that the restoration on the DVD has a much less frame rate than on the bbc clip
I'm hoping all the frames will be restored to this and not lost

They appeared to have gone for a more tele snap reconstruction over actual moving images. I presume this is due to it appearing to jarring going from motion to stills. The work involved to get it looking good would be tremendous, possibly years of restoring.

hopefully, all pictures were preserved.
Perhaps, in time, technology could remove jarring
