Slide Scanners, which one?

    Hi All,

    Just thought I would let you all know that I did purchase that DiMage
    Scan Elite 5400 slide scanner.

    I played with it one afternoon and was satisfied but do see a big need
    to really read the manual which appears to me to be confusing and
    incomplete, from what I have read.

    To go back to the beginning, the hardware came with Dimage Scan software
    and Photoshop Elements for use in both Macintosh and Windows computers.
    The Scan software installed in my Macintosh (OS 10.3) without a hitch.
    My computer could not read the Photoshop Elements CD, at all. I then
    tried that CD in a laptop, running the same OS, with the same results.

    I have lots of questions but I will start with just one, on Resolution.
    I want to be able to make slide shows with the slides I scan and also be
    able to print out 4x6 photographs. Do I scan twice for the different
    uses and what dpi do I scan the slides in at?

    OK, it's two questions (G)

    Thanks!

    Scan at the highest resolution for intended uses, and then re-scale in
    software for any lower-res purposes.

    The scanner software should have a pre-defined job type for a 4x6"
    print @ 300dpi, which will a) lock the cropping box at the correct
    aspect ratio, and b) adjust the scanning resolution so that no matter
    the size of the crop, it will result in 4x6", 300dpi output.

    I scan as a tiff file for archiving ...it is lossless...when emailing or
    using for web page save as jpeg in smaller size.

    Tiff is bigger file size but worth it since I can make up to 16x20 with no
    problems.

    You have the opportunity to learn a great deal because you have a very high
    end machine.
    In order to take advantage of it you need to become comfortable with a
    photoprogram that allows for color management. Any Photoshop program, PSP or
    Corel Photopaint will do.
    In the beginning I think it is a good rule to always scan 35mm materials at
    2000-2400 dpi which will create file sizes between 20 and 24mbs when saved
    as TIF files.
    You will never regret always saving the original scan in an untouched
    lossless file format.
    CD or DVD storage is cheap, but later rescanning to a larger file size is
    time consuming and may be impossible if you lost the original negative or
    transparency.
    When you learn more you will have scans that have enough information to just
    about anything you want to do.
    You can always downsize the file for printing smaller pictures. In fact your
    software will do this anyway.
    However if the original scan does not have enough pixel information there is
    no way to accurately generate a larger file to make a high quality larger
    print or to crop the image and still get an adequate print.

    So, it is best to scan once at a high resolution.

    I have Photoshop! Configuring for color management has always confused me.

    Can TIFF files be used in slide shows and in printing small photographs
    or do I have to convert the TIFF files to JPEG? Don't I need JPEG files
    for emailing?

    Scan once into TIFF at high resolution. Once you have a hi-res scan
    in a lossless format, you can crop, downsize, and convert that image
    into any size and format you desire for the use you intend.

    For printing, I generally use the full-size TIFF file and let the
    software/printer driver worry about the physical dimensions.

    For viewing on a monitor, I convert to lower-res JPEGs - whether for a
    website, emailing, or a slide deck.
