    Hi

    Couple days ago, I process my negative film and had it scanned onto a Kodak
    Picture CD for the first time in Kmart. I was shocked to find that the most
    file size are under 200KB mark at a resolution of 1542*1024 pixels, which I
    believe is a very low resolution for any kind of reproduction. I went
    back to Kmart, but they didnt seem to have a clue, just told me that was the
    resolution set by the technicians... and could not provide me with any sort
    of guidelines.....I don't think i will go back there again if that is their
    standard practice.

    As I have never tried film scanning before, can anyone tell me about their
    past experiences? or does anyone know the standard guideline for Kodak PCD
    services?

    thank you

    That is about all you need to do a 6x4 print and that is what the local mall
    labs do. Buy your own, I bought a Canon 8400F and it does a pretty good job
    for pretty low cost.

    thanks Pete,

    I guess I can't ask for too much from the local mall...but they were the
    only shop open on Sundays.

    I am not looking to do large amount of film scanning, because I shoot mostly
    on my canon digital SLR.

    I bought some old vintage rangefinders and a russian LOMO LC-A, just been
    playing and testing them with films.......so I just want to find some decent
    and relative cheap way of coverting to digital format so I can view them on
    my computer.

    So I suppose other "more" professional labs should offer higher quality
    scans?

    I would try one of your local photo shops, they might offer a better
    service, they might not of course.

  5. Kodak *used* to have two services - Picture CD, which is the crappy
    low-res one you got, and Photo CD(I think) which gave higher resolution
    scans.
    Like your other respondents said, it will give a fairly good 6x4. What
    more could you want??? (O:
    It's fun but hard work, and you need a fairly decent scanner. The
    cheaper flatbeds with adapters are pretty mediocre, but both Epson and
    Canon make quite good ones starting around the 3200ppi level. True
    film scanners are a bit more expensive, but you get more quality
    per-pixel.. A 4800ppi flatbed will give you not much more quality,
    possibly less, than a 2700ppi film scanner. Most film scanners
    nowadays are up at the 4000ppi or 5400ppi mark, like the well known
    Minolta. Dust can be a big problem, so those scanners which use IR
    dust removal systems (ICE/FARE/etc) are worthwhile. Color correction
    of negatives can be challenging with some scanners, and dynamic range
    is a big issue with slides. Herewith ends your twenty second lesson..
    (O:

    In other words - ask around before buying yourself into this field!
    And if you are sensible, maybe you should just find a decent film
    scanning service - try a camera store instead..

    <--- I don't know if Canon has em, but Nikon has a slide copier setup dated
    back to the last millenium .
    Maybe worth having a look.

  7. PhotoCD is still available - if not still from Kodak, then certainly from
    private labs. Still the best way of getting large-format transparencies
    scanned to digital with minimal stress, by the way :)

    PictureCD is just a CD-ROM with some relatively low resolution JPEG scans
    on it. PhotoCD is its own unique format, both in terms of the CD itself
    (though it's nothing radical) and the actual file format, which contains
    five or six different resolution versions of the same scan in each file.

    Probably an ignorant question, but ...
    Does film/negative scanning need a higher dpi than photos? I thought
    if you scanned photos at 300 dpi then this was sufficient for 6x4 and
    blowing up a reasoble amoung???

    Mr.T Guest

    Of course.
    300ppi is required for the final print, so an 8x12" print for example would
    require 2400x3600 pixels.
    To get that from a 35mm negative requires more than 2500 ppi.
    Hence 2700ppi is considered the useful minimum for a film scanner. 4000ppi
    is common these days.
    That's approaching the resolution limit of most films anyway.

    The 1542x1024 pixel scan above would be fine for a 4x6" print, which is all
    it's intended for.

  10. Probably an ignorant question, but ...
    It's more often the replies than the questions.. (O: We all have to
    start learning somewhere about new topics!
    Yes it does.
    As Mr T explained, if the original is a photo that is 6x4, clearly it
    has already been enlarged significantly. So to get enough resolution
    off that small original piece of film, about 4x (linear) smaller, you
    need correspondingly more resolution.

    And as previously noted, most serious film scanners are at least 2700
    ppi, more likely 4000 ppi - which will resolve most detail off most
    (colour) films.. Then there are drum scanners, that go to 8-12,000 ppi
    or higher - but you need a mighty fine slide/neg to justify that, and a
    deep wallet.
