Bug ID: 444501
Summary: Face detection, write name tags (metadata) to file -
Changes date and time on photo
Product: digikam
Version: 7.3.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: major
Priority: NOR
Component: Faces-Detection
Assignee: digikam-bugs-n...@kde.org
Reporter: dajo...@gmail.com
Target Milestone: ---
SUMMARY
I am running digikam 7.3 and did a face detection, enabled write name tags to
photo metadata. After tagging several faces I run face recognition and digikam
started to change date and time on photos. I did not discover this immediately.
Since I upload photos to google photos I saw that old photos appeared as taken
in October 2021. Checking the photos, surely the date and time had changed.
There must be something seriously wrong on how digikam processes face
detection/recognition/writing name tags to photos. Not sure what exactly is
causing this and I do not know how to investigate either.
STEPS TO REPRODUCE
1. Enable writing name tags to photo
2. run detect faces
3. train algorithm by adding nametags
4. run recognize faces
OBSERVED RESULT
photo time and date should change, maybe
EXPECTED RESULT
no change other than adding name tags to photo
