Can I change incorrect 'picture taken on' date/time?

    On a recent trip, I forgot to reset the camera date/time to reflect a 7
    hour time zone change. Therefore, all of the pictures taken have an
    incorrect date/time stamp.
    Because I traveled from East to West, some of the pictures taken in the
    evening, are listed as being taken the following day, in the early
    morning. Disconcerting!

    Is there any way to correct this date group which is stored with each
    picture?

    Additional info
    I have software to modify the date/time of file properties "Created on",
    "Modified on", and "Accessed on", but this does not change the picture's
    internal data.
    Picture format is .jpg, camera is HP R707, which stores camera settings
    with each photo. Computer uses Windows XP.
    Camera type shouldn't matter, as almost all digital cameras store the
    date/time with the image.
    Forgetting to adjust the time, would probably be a common error, made by
    many people, and a utility to correct the picture's internal date/time
    would be useful.

    Can anyone help?

    Exifer [1] does what you want.

    tried exifer.

    I can read exif data from pictures taken with my OLD camera (Kodak
    LS443) but cannot read the data from its replacement (HP R707) Exifer
    says 'No Data'

    HP site says 707 uses exif 2.2 standard, and exifer site says program
    should detect versions up to 2.2

    Sounds like someone goofed.

    Does that cause a problem?

  5. Use Greenwich Mean Time then calculate based on venue.

    I use GMT a lot, and am comfortable using it at work. My pictures are
    not only for my benefit. Others, who can't easily convert times, will be
    looking at the pictures which will not seem to make sense to them.

    An example

    A photo taken at a company banquet at 2100 hours on April 14 in Hawaii
    would display a date/time stamp of 0700 hours April 15.
    The boss wonders why the party lasted until dawn?

    Another factor is to make sure that you keep track of the location, it's
    time zone, and whether DST is kept, and in effect or not.

    So using local time is more logical. A picture taken during the day,
    would show a local time stamp making it easier to determine exactly
    where you were at that time.

  7. I did the same thing once; had a 8 hour error. I think I ended up using
    a program called exifer. It's particularly nice for this, because
    there's a way to tell it to change the date by a certain amount on each
    of a whole batch of photos. So fixing the EXIF data was nearly
    instantaneous, once I figured out the right way to do it.

    It took a little longer to move all the photos into the correct
    directory. I use Breeze Downloader, configured to automatically store
    each image in a directory named for the shooting date in the EXIF data.
    Thus, a bunch of images ended in the wrong directory and had to be moved
    by hand.

    You can do this with Adobe Photoshop Elements or Album
