10.4: Set a photo file's creation date to the photo's date
Authored by: mesa on Jan 05, '07 09:14:34AM
I usually use jhead to access exif data, it has a cli and so isn't everyone's cup of tea.

One point of clarification is that there is no such thing as "creation time", ctime as it is usually called is the time of metadata change. As most files don't have their metadata changed it is often mistaken for creation time.

10.4: Set a photo file's creation date to the photo's date
Authored by: Lankhmart on Jan 05, '07 10:38:17AM

Yes, there really is a creation date for files on HFS+ disks, completely separate from the ctime. None of the unix-based tools on OS X are aware of it, and they all fail to preserve it (using rsync or ditto or tar, for instance), but if you just use Get Info in the Finder you can see it. This is one of the key pieces of Mac-specific metadata that nearly all backup software fails to preserve.
