Are there good solutions for analog negative scanning and beamer projection in reasonable resolution

Discussion in 'UK Photography' started by Andreas Böttcher, Jul 20, 2009.

  1. Dear photo-fans!

    I am thinking about getting rid of my analog negatives, of my dia positives
    and of my analog dia projector. But which equipment is really good? I want
    to keep the resolution and optical quality of my analog material. The films
    must be scanned so that no lack of quality occurs. Furthermore the
    presentation of the then digital present material with a beamer must have
    the same quality as a Leica-Pradovit dia projector. But the conventional
    video beamers have not sufficient resolution.
    Do you know such equipment which is suitable for that purpose?

    Best regards,
    Andreas Boettcher

    There are dedicated slide scanners. I have just bought a Nikon coolscan
    5000 I am sure there are others.

  3. No.

    There are plenty of scanners up to the job, but I doubt if you'll find a
    projector that comes close to what you're used to. This is called progress.

  4. Yes, this is clear !
    I do not really want to scrap it. I just would like to harmonize all
    material on one (digital) level. But keep the originals in a box in my
    cellar.

    Thank you so far for answering!

  5. Do you have access to a macro lens and extension tubes? Copying using a
    camera on a tripod (especially in RAW) can give very good quality and once
    intially set up can be done like a production line.

  6. OK, I can scan quite well my dia-positives and my negatives and can thus get
    reasonably good digitalized data files. OK, this seems to be solved and
    possible with todays technology. I learned quite a lot from searching in the
    net and from these forum comments. So the preservation of my originals
    (dia-positives als film-negatives) will be possible. This is the one
    important part and this is OK. So I can order poster-prints in reasonably
    good quality.

    But for presenting these photos from digital data I need a beamer which
    gives the same quality and spatial resolution like my dia-projector
    (Leitz-Pradovit) to be able to replace this analog device. But I didn't find
    such a good beamer. Such a beamer for me does not need a very high
    brightness (ANSI-lumen). At home I can darken the room by darkening the
    window, as I do it as well by presenting analog pictures with the
    dia-projector. But is there anywhere such a digital-beamer available having
    such a high spatial resolution? A resolution like my traditional analog
    device? If this is possible, is such an equipment affordable for me as a
    private user? (I would accept to pay for example 2.000,- Euros but not very
    much more.) This seems to be the more difficult point of the case.

    If somebody might have an answer to this, please let me know your opinion on
    that.

    As this is a UK forum and as I am a German guy please excuse my poor
    English.

    You can get a full-HD (1920x1200) projector for this budget (even half
    of it). DLP projectors will offer better contrast, but lower saturation
    and you might see it flickering. I would go for LCD.

    1920x1200 is not really going to match the colours and contrast of a
    good projector and 35mm slides (especially Velvia or other high
    saturation and contrast slide film), but it will be fairly close in
    resolution.

    Digital projectors used in cinemas can be very good indeed- there is a
    standard 4k resolution, which is about 8 megapixels. These projectors
    are still expensive ~€100,000.

    Nonsense. 1920 x 1200 is only 2.3 million pixels!

    Scanning film at 4000 pixels/inch (157 pixels/mm) yields a digital
    image with 21.4 million pixels.

    In other words, a scanned slide has an order of magnitude more detail
    than could ever be shown on a 1920 x 1200 digital device.

    If the OP desires the best possible quality of projection for his mix
    of film and digital images, his best course of action would be to have
    his digital images recorded on to 35mm slide film and project them
    along with his original slides using his Leica Pradovit.

    Expensive, though. ;-)

    If you scan it at 1 million pixels per inch, does it get any better?

    Have you compared a down-sampled and sharpened 1920x1200 file from a
    full resolution scan of a 35mm slide, projected by a full HD projector,
    to the original side projected alongside?

    I have.

    The resolution is not a major problem at sensible image sizes/viewing
    distances.

    You can scan to any resolution you like, doesn't mean there is any
    information in the file.

    Not very portable, But a Large Screen TV using HD images ( 1920 X 1080 )
    will give the best results.

    A lot of modern TV's also have a monitor input which makes for an easy
    display from a laptop. It is also surprising how much eyes accommodate when
    looking at projected images so that quite often low resolution digital
    images look better on a screen than a much higher resolution 35mm slide. I
    always found this surprising when seeing the two side by side.

    To even ask that question, you have comprehensively missed the point.


    Yes, I have. I show projected images on regular basis. The question
    of what to do with slides has been quite a challenge - the problem is
    that the audience can tell all too easily which are digital and which
    are film images, and they strongly prefer the film images because of
    their much greater detail.

    I tried projecting digitised scans of my slides together with the
    digital images but the reduction in detail was too great and the show
    was not well received. So I experimented with having some 35mm
    slides made from my mostly 12 MP digital files, and projecting them
    along with original slides. The results were excellent - people could
    not easily tell which images were originally on film and which were
    digital, and the overall high image quality went down very well.

    The only problem is the cost - I was charged a whopping £3.50 per
    slide which is apparently a heavily discounted rate. Even so, I am
    considering having several hundred digital images made into slides so
    they can be projected along with original 35mm slides in one show.

    It's easy to convince yourself that a 2.1 MP digital projector or LCD
    TV gives you all the quality you need if you have invested a lot of
    money in one or the other. People will go to almost any length to
    delude themselves to avoid the dreaded "Buyer's Remorse".

    It was the same a few years ago when people routinely claimed that a
    1.2 MP digital camera could compete with film. Then it was the turn
    of the 2.7 MP Nikon D1 SLR. Of course it is now generally known that
    you need *many times more pixels* than that to rival the quality of an
    image on a high quality 35mm slide or negative, and those early claims
    (and the people making them) now look completely ridiculous.

    I don't deny that one of your own digital images shown on an HD TV can
    look very pleasing, and give you a lot of satisfaction but, compared
    to a good 35mm slide, the detail simply isn't there, no matter how
    many times you try to tell yourself that it is.

    But delusion goes with digital photography like bread and butter, or
    bacon and eggs. If you are willing to be fooled - especially after
    investing £££ in digital equipment - then you will be.

    There is a desperate need for digital projectors with massively more
    pixels than we have at the moment. As with digital SLRs, it will
    happen, but it will take years and the projectors will be very
    expensive to start with.

    Until then, we have to make do with what we have.

  12. 100.000,- Euros !?!?
    So I have to decide if not to enlarge my house instead for buying such a
    monitor. Or not to pay for the university education of my daughter. Or not
    to buy a Ferrari. But to get such a monitor.
    OK, I will better forget such a monitor.
