Converting JPEG to TIFF...keep EXIF data?

    I've been looking for a program that can batch convert the JPEG files from
    my Nikon D70 to TIFF files for lossless storage. The problem I've had with
    the programs so far (such as IrfanView) is that when converting to TIFF, all
    the EXIF data that existed in the JPEG is lost. Are there any (preferably
    freeware) programs out there that will maintain the EXIF information when
    doing a batch convert?

    Why on Earth do you want to do this? It makes sense to convert JPEG
    files to TIFF, PNG or other lossless format for work in progress. But
    you gain nothing at all and waste a lot of space by batch converting
    JPEG files into TIFF files.

    The only thing that happens is that you set in concrete any
    peculiarities of the codec that you used to decode the JPEG files. It
    wastes a huge amount of space and gives you no new useful information.

    I'd think it would be dependent on other formats supporting the embedding of
    EXIF data, which to the best of my understanding is currently specific to

    What you might find useful is "EXIF UK" ( -
    it does just about anything you could imagine with EXIF data, including
    exporting it to an Excel file for a group of images, to renaming files to
    include EXIF info, to comparing EXIF data across multiple files (handy for
    checking bracketing results, for example). And... it's freeware.

    You are converting from JPG into TIFF?

    Other than eating up more storage space, that will do nothing for you. Once
    an image is JPEG, you can't 'add' quality to it by saving it in a better
    format. The TIFF from those JPGS will be of equal image quality. The JPG
    wont lose any more quality that it has right now(unless you resave the
    images every time you view them, which nobody should do) over time, so just
    keep them as they are. If you want to save to TIFFs for quality, then shoot
    in RAW mode.

    I have a D70 myself. After the first week of just getting a fell for the
    camera, i now shoot only RAW.

    I'm not looking to make the pictures "better" by converting them to TIFF; I
    just want to make them editable in the future. I make modifications to the
    images out of the camera (adjusting curves, rotating, etc.) and I don't want
    to re-save in JPEG format.

    You lost me a little here. If you "want to make them editable in the future"
    JPEG is just as good as TIFF. If you "don't want to re-save in JPEG format",
    then just don't. }:) *IF* you edit a file and decide to save the results, you
    can always choose a lossless format for the save.

    It just occurred to me that
    perhaps you mean to imply that you intend to edit *every* picture from the
    camera, and that your favorite photo editor for some reason makes it difficult
    to select an output file type different from the original file type, then perhaps
    it might make sense. In that case, I'm afraid I can't help with your real

    Personally, I think for ordinary, home users, the "JPEG loss fear"
    is way overblown. Ordinary consumer users will never notice the slight
    loss that a couple of saves of high quality might introduce. Of course, if
    you make your living with your camera (or are an artist, or are terribly anally
    retentive, or whatever), that might be an entirely different story.
