I'm scanning from a large commercial scanner at the local library and saving to a thumb drive. One of the settings available in the twain input window is "Print Mode Key" and the options are "Text" Fine 1" "Fine 2" and "Photo".
I scanned the same image with each setting and opened them in Photoshop in a tiled display. Big differences. I would guess that photo is closest to raw mode and that the others are tweaked by the software. I tried googling but got no where. Can anyone shed light on how the software works? I'd rather scan in raw mode and if the image needs to be tweaked, I'd rather do it myself.
Scanner is a Konica/Minolta MS6000 MKII
Subject matter is 1950s newsprint on microfilm
