File Formats question

Discussion in 'Digital Cameras' started by P and H Macguire, Dec 5, 2003.

  1. I'm a bit confused about the best choice of file format. I am in the process
    of scanning a lot of 35mm slides and B/W negs from long ago. I want to keep
    some on my HDD for viewing/e-mailing and also want to archive them to CD.
    What would be the best combination of formats bearing in mind size
    considerations? What's your system?


    Regards and thanks in advance

    What would be the best combination of formats bearing in mind size
    To minimize file size and stay with a lossless format, PNG will do the job.
    They may take a few seconds to open, because your CPU has to decompress them
    when you click on the filenames.

    Uncompressed TIF is probably the most popular storage format, but the file
    size is bigger. With CDs being so cheap, I would think that you wouldn't be
    too concerned about file size.

    I's stay away from proprietary formats for long-term storage, as software in
    the future may not support those formats. You probably have the greatest
    long-term ability to read your stored files by sticking with TIF and PNG.

  4. If you are not concerned with space considerations and may want to edit these
    pictures in the future after having been archived, I would scan them as TIFF.
    The sizes will be larger than JPG or PNG, but you can get a lot of pictures on
    CD nonetheless.

    ----------
    RM: It pays to get various opinions of course. Mine is that if you are
    going to spend a lot of time scanning your slides and negs, then you
    may as well do it only once - and do it properly. This means saving
    the files to TIFF and then preserving them as your master copies.
    After this you could do what you want - which means making low quality
    JPEGS or (for some jobs) GIFs for the web.

    If you were concerned about the space required for archiving your
    TIFFs, you could compress them with the *lossless* LZW facility.
