Scanned slides don't match projected image

Discussion in 'Scanners' started by David Causier, Dec 24, 2004.

  1. From a roll of film developed and printed by a local processor, I've
    noticed that my HP4C can duplicate the print nearly exactly, whereas
    scanning the negative of the same picture with my Nikon 4000 rarely
    matches the print quality, although the detail is usually sharper. The
    same applies when I scan slides-the scanned image is never of the
    quality of the projected slide. The problem seems to be somewhere in
    color management in the Nikon. I'm getting ready to batch scan several
    hundred slides, and obvioulsy don't want to have to tweak each one.
    Any suggestions? Thank you.

    Both my Microtek & Minolta have film 'brand' settings that can be tweaked
    and saved as 'profiles'. Doesn't the Nikon for its greater $$$ have this?

  3. No, despite its $$$ cost it doesn't. And the problem I described
    occurs with Kodak and Fuji film.

    You may have to scan, then sort into similar results folders. IF you use
    PhotoShop, then you can make an action to color corrrect and appy to each
    film type/result group in a batch.

    I found Fuggy to be the worst to scan over the time I used film.

    If you are using NikonScan try turning the color management *off* and
    see what you get. You might need to play with the monitor profile
    as well. Also there is a bit you can do in the "Advanced" settings
    with the color channel gain to create a custom setting.

    These things *sometimes* are plug and play, but most often require a
    lot of work to get the monitor, and printer to agree.

    One question, does your monitor faithfully reproduce the colors from
    the slide and from the print or is there a difference.

    Generally you end up needing to create a profile for the scanner and
    for the monitor. If the monitor is reasonably close for the scanned
    prints but not the scanned slides, then you need to create a custom
    profile, or profiles for the scanner.

    IF you have a number of film types for slides and for negatives but
    the results are off for all negatives and slides, then you most likely
    will need to create a profile for each type.

    Have you tried using VueScan? It works well for me.
    OTOH you have control of virtually everything in VueScan so it has a
    much steeper learning curve than Nikon Scan. Nikon Scan has some nice
    features that make it easy to use.

    In my case using a Nikon LS5000-ED I did not have to create a custom
    scanner profile, or haven't so far and I think I've gone through near
    20,000 slides and negatives so far since last March. I've lost track
    of just how many so my numbers may be off a tad either way.

    This is a function of the software, not the hardware. NikonScan is an
    "automated" program that is supposed to do it all, but doesn't.
    In general I find it works quite well on my LS5000-ED.

    On the NikonScan 4 header bar, under <Scanner> you can select
    <overall>, or <User> settings. You can adjust the settings on the
    [Tool Palette] and then save them to use as a custom profile.

    Get the settings so you are happy with the results and then save them,
    but remember there are many variations to both Fuji and Kodak films.
    Each brand has types and speeds. Even the different speeds for the
    same type take different settings. On top of that you will find that
    both negatives and slides change with age which requires slightly
    different settings. I have several scanning programs and the one I
    prefer and use the most is VueScan although it does have some short
    comings. I haven't found any that are perfect.

    Unfortunately most scanning is not a "plug and play" sort of thing
    although sometimes you get lucky.

    Nikon 4 uses the Digital ICE feature built in the scanner.
    It basically does an infrared scan of the slide or negative and then
    subtracts the results from the regular image. Its latest
    incarnations are far superior to post processing.
    I prefer ROC in the scanning package, but a raw scan with the
    exception of Digital ICE can be post processed.
    The new high resolution scanners can have a relatively steep learning
