<exif:GPSLatitude>26,14.0798N</exif:GPSLatitude>

becomes:

This happens only if you have GPS-Tags in your image file and safe it in Photoshop CS4 as a jpg. If you look at the image files in a text editor you'll see that for example in the tif: 26,14.0798N simply becomes: exif:GPSLatitude="26,14.0798N" in the jpg. Unbeleavable, isn't it!

I am attempting to modify the date value stored in the image which I just assumed is the same value that the filesystem uses to display the image's creation/modify date in the Finder. I guess I'm confused as to what value inside the image the filesystem is using to display when the image was created/modified. I will take a closer look at the EXIF spec and update the post with any new discoveries. Thanks for commenting. Thanks Phil for the clarification.

If you are talking about the filesystem date/times (as opposed to information actually stored in the image), then exitool only has access to the file modification date (via the "FileModifyDate" tag). ExifTool can not be used to access the filesystem creation date. You wrote: “I have been unsuccessful in copying over the data that describes when the source image was created & last modified.”
