It is always best to scan at the highest practical resolution. I would put my money into high res scans, digital storage and an image database and forget the microfilm.

>manuscripts, and some photos. We are scanning at 400 dpi resolution in

>We are interested in hearing from others whether 400 dpi 8-bit grayscale
