The ProblemI was organizing some photos the other night and found a whole bunch of photos with incorrect dates. I checked my camera and, sure enough, the battery had died at one point and the date and time were set wrong.
My Attempted FixI checked the date and time on the camera and compared it to the actual date and time. I then set the camera to the correct date and time so that, at least from now on, it will record the correct date and time. I also added "Must prompt for date and time after detecting battery failure" to my list of criteria for a new camera.
I found that MS Pro Photo Tools has a way of fixing the date and time in the EXIF, IPTC, and GPS tags in my photos. So I tested one. I loaded it up into Pro Photo Tools and set the date and time and told it to copy that date and time to all three (EXIF, IPTC, & GPS) tags. And then I saved the image.
In MC, I took a look at the metatag information in the Tag AW for this image. I could see the information that Pro Phototools had written to the tag and I could see the date information there and it looked correct.
I then ran Update Library (from Tags) on that image and took a look at the [Date (filename friendly)] field. It didn't match what was listed in the EXIF or IPTC tags. The date was still the original date and the time was wiped out entirely. Where does MC get the date information from on an image? If I look at this photo in Windows Explorer, it shows Date Taken as the date and time that I set in Pro Photo Tools.
So now I'm stymied. I have to admit I'm kind of clueless about most of this EXIF and IPTC stuff. It would seem to be fairly simple to update this information in my images using the date & time offset that I have and have MC pick up that new information. Anybody know of another way that would work?
