Microfilm into wall size poster please??
 

Just get as high as possible resolution drum scan of the original film.
Internegs, microscopes, etc will only degrade the final image.

You'll either have to scan the microfilm at a very high resolution or
make an inter-negative.

Ideally you can find someone with an old 35mm camera hooked to a
microscope. You could then shoot an inter-neg using ortho film and
get a pretty good image off of it.

Litho film as an interneg will give you a hard edge at boundaries, so it
will "sharpen" text and halftone images, but it might not work well if you
have continuous tone.

NO copy, regardless of what it's done with is better than the original.



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.
