Incorrect date assigned to photo

I did an initial import of my photo library and found that some photos have unexpected dates assigned:

grafik

  • PS thinks that the picture was created on 2002-12-08, 12:00.
  • According to windows, the picture was created on 2013-09-28, 16:05.

exiftool shows both dates (see below): The correct deate as “Date/Time Original”, the incorrect one as “Create Date”. Since all photos in my collection from this particular smartphone have this date assigned, this inconsistency was probably a bug in the phone’s camera app.

So one can probably argue whether this is really a bug in PhotoStructure, but maybe it makes sense to tune the heuristics here?

Welcome to PhotoStructure!

Interesting, you’re the second person to report a spurious create date:

I believe CreateDate is valid for most files, though, so I don’t want to simply ignore that tag.

Perhaps if CreateDate, specifically, is this 2002-12-08 date, it gets ignored?

I can also make the tags that are examined for captured-at be configurable.

Hi Matthew,

oh interesting, I did not find this posting. So maybe a bug in some old android version (I believe the Huawei in my case had a version 4 running)?

Configuring the tag set for captured-at looks like a rather advanced option to me: If - like me - you have an assorted collection of pictures from various sources, you probably are not in a position to really judge the effect of this setting.

In my case, I fixed the deviations manually using exiftool (it was always 2002-12-08T12:00). For future use-cases one could think of plausibility checks (i.e., if both DateTimeOriginal and CreateDate are set, they are probably not more than a few minutes apart)., but your suggestion of ignoring CreateDate for this specific date+time looks easier (and probably more robust).

It’s possible.
The phone I used to capture the pictures in my post was a Motorola running Android 4.4, but only a portion of the pictures captured with that device got the 2002-12-08 CreateDate :thinking:
