This idea came to my mind, when I was reading the thread about "gigabit" film.
One problem with this film is, that normal film scanners cannot really utilize it, because of their immense resolution.
Would a "scanner" setup like the following idea be able to overcome this problem?
Imagine an enlarger with excellent (Leitz, Schneider, Rodenstock) optics which would enlarge the negative not to paper, but to a good flatbed scanner which had a milk glass surface and its lamp being switched off/removed. Would this work to get a high resolution film scanner ?
E.g. my Nikon Coolscan 9000 manages up to 4,000 DPI, which is 160 dots per mm or 80 line pairs per mm.
In case of 35 mm film = an about 4,000x6,000 pixel scan.
Gigabit film manages up to 300-800 line pairs per mm (more than many lenses can do).
A 24x63mm negative enlarged by a factor of 8.333 to a size of 20x30 cm in such a scanner setup (assumed 3200 DPI scanner) would, following a simple and naive computation result in an effective scan of 3200*8.33 = 26,666 DPI = 1000 dots per mm or 500 Line Pairs per mm.
I know there would be loss due to optics, diffusion and such. Enlarger lamp luminosity would also need to be adjusted.
Anyways: Could this work? Does anyone of you have experience with scanning from an enlarger projection?
I've seen top quality Heidelberg and Creo scanners go for less than £500. on ebay, drum scanners can be had for nothing if you look hard enough, each of those sounds easier and better than what you are after trying. Shooting sections through a microscope then stitching sounds easier.
