P: "Data/Time digital" not shown correctly in Lr 3.4

Thanks Sven, I've reported this bug to the Lightroom engineers.

The issues discussed here are some symptoms of more extensive problems with LR 3.4's handling of metadata dates. See my problem submission:

Thanks for the explanation. This appears to be a bug to me -- when you change the capture time to a specified date and time, it changes every date it's got. It probably shouldn't change DateTimeDigitized.

MWG guidance allows for separate concepts of "Original Date" and "Digitized Date". It does not suggest that they be mapped together, but that appears to be what LR3.4 is doing. I think this is a bug in the new metadata model.

Changing the date in Lightroom should only affect the "Original Date", not the "Digitized Date", IMHO. I could see people also wanting to change the latter, so perhaps that's worth a feature request, but I feel that the current behavior is a bug.

Thanks. I've asked someone from the Lightroom eng team to review both topics.

I don't think they're necessarily related. I just happened to notice the XMP:MetadataDate time zone issue when I was looking at metadata for this topic, and I remembered that others had noticed the same thing, so I wanted to get it recorded. But I don't see offhand any relationship between the two topics.

Yes, Mark, what I've done is I changed the capture date/time using Lr's "Edit capture time" (or similar) command in the Metadata menu to change the date to the original capture date and the time to 00:00:00 (because I don't know it).
Maybe I should add that I did not export the changed metadata from Lr to the TIF file - hence the TIF file is still the original one.

Here are the relevant metadata fields, as reported by exiftool v8.5.6 using "-a -G0:1 -s":

[EXIF:IFD0] ModifyDate : 2009:03:13 15:21:10
[EXIF:ExifIFD] CreateDate : 2009:03:13 15:21:10

These are the exiftool names for EXIF DateTime and DateTimeDigitized.

So where is the 1988 date coming from? Is this something you did in Lightroom after Import? It doesn't show up in the original.

Hi, since the TIF test file is about 25 MB and I did not want to change it in any way in order to keep it as it was imported in Lr, I've uploaded it on a web-drive:
Here is the access (which I keep live for a week):

Hope that helps - and I hope that I will get back my information as it used to be in Lr3.3.
Thanks

Hi John, is the issue you just posted http://feedback.photoshop.com/photosh... related to this topic?

I just reviewed my catalog of scanned images. Looking at images that were imported and had their capture date/time changed using LR 3.3, some have the metadata field XMP:CreateDate set to the scan date (correct), and some have it set to the same value as XMP:DateTimeOriginal (the capture time, which is incorrect). LR 3.4 is displaying the value of XMP:CreateDate in the "Date Time Digitized" field of the Metadata panel.

I can tell from the metadata that there was a different workflow involved for the two sets of images, but I'm not sure as to the details. There's pretty clearly a bug somewhere.

As soon as you post a problem image, we might learn more about what's happening in your catalog.
