But there are no makernotes in the straight-from-camera files, right? So I wouldn't be losing anything?

That should let me run the date correction command, which will take care of the big things, but I would like to restore the EXIF data completely to how it was straight from the camera. Looking at the edited vs unedited images, how could I do that? I know exiftool allows copying from one image to another, so I'm guessing that would be involved. Would it even be possible?

Thanks.
