    Hello

    I was wondering if anyone knew if one could use a pinhole camera for making microfiche sheets, with a rediction of 1/10 or 1/20 of the original.

    Medium Format
    My evaluation :

    A4 / 10 -> 30x20mm²
    reasonable focal for this size : 40mm
    optimal pinhole for this focal : 0,24mm
    resolution : 0,3mm blur circle
    separation : approximately 100x70 pixels

    Is this OK ? I think NO

    A4 / 20 would be worse ; why not use a lens ?

    Bye Paul

    Thank you.

    This was mostly more of a "Can I do it?" sort of thing.
