Is there anything digital will never be able to do ? - Photography

Try having high resolution slides made from digital images. Few places do it, and it can be quite expensive. I haven't seen any $5 disposable digital cameras. Perhaps one might need an expensive digital slr to be able to take very long exposures of a few minutes? Perhaps even then there might be too much noise? Are there any digital cameras with a 25 ISO mode? Any with a high quality 1600 or 3200 ISO mode? Giorgis wrote:  ...

    Never is a long time, but digital will always have a problem with large
    area arrays. The difficulty of producing CCD and CMOS sensors goes up with
    the area of the sensor. With film you can easily get 8x10 sheets. Film could
    easily be supplied in much larger sizes. There are digital systems that
    employ line arrays to scan large areas, but this only works with static
    subjects.

    How about Xrays?

    I'm only really experienced with the Nikon line of DSLR's.

    My D100 & D1h can both get very good results at ISO1600 - better than film.

    The D100 can take exposures of about 2.5 minutes before it starts to get
    noisy at ISO200 (that's it's minimum ISO).

    The D1h is super clean in ISO noise compared to the D100.

    The upcoming D2h will be far better as well, as it is using a "CMOS like"
    sensor and can go to ISO6400 + 2 stops extra, and indications (from leaks,
    rumours) are that it will be very usable at ISO6400.

    I believe the current range of Canon DSLR's can do longer long exposures
    with their CMOS sensors, but I never really go over 30secs anyway.

    Funny, I heard the exact opposite account from a
    physician friend -- hospitals are turning to digital
    imaging in a big way. Primarily because film is
    expensive and film processing is expensive.
    But also so that images can be more easiy
    shared and routed.

    I'm pretty sure my sister in law who is an X-ray technician at a clinic said
    that they have gone digital for full scale X-rays. I don't know whether
    this is done by scanning film, but from what she said it sounded like the
    whole thing is a digital process. The important thing to her was the
    ability to tell a patient almost immediately that the X-ray was OK so the
    patient could leave. Viewing the digital X-ray was also easier because you
    could zoom in for a closer look. Sending copies to the doctor and
    specialists was much faster also.

    A few months ago I had a couple of x-rays, the first with a film
    machine, the second with a digital machine apparently made by Canon. I
    later found out that the radiologist would have given me a copy on
    floppy disc if I'd asked, unfortunately I wasn't at my sharpest at the
    time. <:^(

    The biggest thing that *I do* miss about film is the handy little
    plastic pot that 35mm film comes in. Use those for loads of things.

    There used to be places that sold rolls of exposed but undeveloped
    pictures to amateur photographers. s, of course. That's hard to
    do (with anything like the same feel) with digital.
