    <pre> Has anyone experience in comparing 8 bit greyscale scans
    (ideally captured on a Zeutschel or another bookscaner) with black and white photographs?

    What are the general criteria for comparison ((e.g. tonal reproduction, number of colours in black and white photographs) and is there any literature about this issue?

    To what extent is the quality of greyscale scans comparable with b/w photographs?

    Many thanks, Norbert
