I believe they use a machine that's like the reverse version of a digital film scanner that scans a digital image directly onto the film stock. I might have over simplified the technique there though? That sounds very likely; with the right light source (laser ?) I'd imagine that you could "write" the image directly onto the emulsion. Is there any forum member with more detailed knowledge ? |

Not totally off topic (as it's about archiving techniques generally), whatever happened to the idea of recording the waveform of a VT optically onto a t/r as a means of archiving TV programmes more reliably? This is an idea i've heard bandied about for a long time and at least one friend who is well versed in tech knowledge reckons it's an alternative that is possibly more stable than leaving them to the long-term uncertainty of the digital / data method. I know that some basic tests were at least attempted.

When I mentioned it some time ago on the restoration team forum someone said it was like making photographic prints from digital camera files; LED or DLP type technology. |
