That's not true with old documents, because copies and use filtration
and even entirely different spectral bands. Consider some document
that was rolled up, burned to a crisp, and then buried for 2000 years.
Sort of hard to read! But, copying it with an infrared camera and it
becomes quite clear.
I've copied letters from my great grandparents that are 170 years old
and are completely unreadable. Using ordinary infrared B&W film they
are mostly readable with great effort. Looked at with a 1.8 micron
TV camera they are as clear as the day they were written.
