Which is the best field in metadata for annotations.

    I have been using the "comments" field in the
    "Image" folder in the EXIF in Exifer for my
    notes for each photo.

    But when I open these photos in iView
    version3.3 the comments appear in that
    programs annotations "source" field, and not
    in its EXIF section.

    I ask: which is the safest field to add
    annotations across several such programs? Is
    it the "Copyright field?

    This is a very real problem.

    First, I wouldn't mess with the EXIF data.

    If you're working with JPEG's, using the comment
    field is probably your best option.

    In theory, IPTC was supposed to address this problem.
    It failed, IMHO. Things tend to break pretty quickly
    once you start converting between file formats and/or
    switch between different software programs.

    It all gets even worse with (camera manufacturer)
    proprietary RAW formats.

    But if you're mainly JPEG based, I'd work with the
    comment field. Most of the time, the data will be
    visible and serious problems (like file corruption)
    are very low risk.

    Thanks. I want to trump this problem by
    having the annotations watermarked across the
    very bottom of the image in unobtrusive type
    that can be cropped away in future if

    I have been using Exifer which has the
    annoying property of wrapping the text about
    1/3 of the width of the image, so making the
    text obtrusive.

    Lightroom is good in that it gives a line of
    watermarked text across the whole of the
    bottom, but bad because it can only add the
    "copyright" text automatically, and it
    cannot, like Exifer string together info from
    various EXIF fields.

    So far I've had no luck with iView3.3 which
    does not seem to watermark at all.

    I guess I'll just have to stuff all the data
    into the "copyright" field in Lightroom.

    Thanks, this sounds good. I'll test and
    report back.
