Multispectral Images

[ReneZ]

I suspect that the 10 years do not specifically refer to the digital image processing.

However, the things that could be done with them are far-ranging. I don't remember where I wrote this, but they could apply a (digital) filter that highlights the presence of iron, to better bring out the faded alphabet in the right margin of f1r, but I was told it would be a big effort, that should be done letter by letter.
I don't know enough about this topic to judge it any better.
