    Anyone know of a place in Melbourne that can scan a
    poster 60 cm x 90 cm at around 600dpi?

    Sounds like a fun flatbed scan and stitch job!

    Take a photo with a high-res macro lens.

    Macro lens for a 60 x 90cm poster? Or do you mean just the 'hi res' part?

    Macro lenses are high-res

    Your on the right track Miro - my thoughts were either shoot a 5x4 or
    the macro on the RZ 6x7. I do either.

    There's a why (either)? You'll most likely pick that up.

    To reproduce the poster 1:1 there wouldn't be much advantage in using
    5x4 sheet in this case.

    And another is if the poster was flatbed scanned why would you scan at
    600DPI 60x90 cm that would make a 650Mb file. Is this manageable? and
    would you get what your after over a scan off a 6x7cm tranny - think not.

    Interesting :)

    If you drum scan the image you still have to deal with the exsiting
    halftone. By photographing it several times with different settings and
    lighting angles you can manage the process more closely and disperse the
    halftone with a new layer of film grain - which is the best gaussian blur
    you can get on a halftone image and still retain the lines and textures.

    Its not so much the difficulty in scanning, it's the potential of Moire
    patterns from a direct scan being output to another imaging device.

    I know. I was wondering if you were suggesting the use of that lens
    because of it's 'macro' or 'hi res'. If it's the 'hi res' part, then it
    it can be any high res lens... doesn thave to be a macro.

    Its not the macro (close up) use of the lens but the performance of a
    macro lens which differs from other lenses. View camera (5x4) lenses are
    the same design as 35mm/MF macro lenses.

    Anyone know of a place in Melbourne that can scan a
    I know... that's what I mean. It doesnt matter really... I was just
    wondering why both macro and high res were specified. I guess you can
    get some shoddy macros too.
