XnView Software

I have some issues with the creation and modification of metadata. To make the work flow transparent I’m describing the steps in detail:

step 1) Giving with Ctrl-D each photo a different description/comment (test 1 ... test 7).
- All boxes in this menu are marked.
- Save.

step 2) copy comment to IPTC description
- select all photos
- Menu Metadata => copy comment to IPTC description

IPTC tabs are created for each photo containing the correct description (test 1....test 7)

step 3) Writing date/time to IPTC
- select all photos
- Ctrl-I => IPTC menu =>date/time => set „EXIF taken“, write to all => close
(options selected: „keep date/time“ and “combine new and existing values => overwrite existing values“)

What experienced is that if I proceed steps 1 to 3 then
- date and time are correctly written to IPTC, but the IPTC caption is modified to the value of the first picture (test 1). All photos have „test 1“
- if i proceed step 1, step 3, step 2, than all comments/description are properly kept plus correct date/time is set for each photo
Is there an explanation for this different results?

I deleted IPTC data and restarted with steps 1, 3, 2., then

step 4) Creating XMP
- All photos selected
- Menu Metadata => create new XMP-data

XMP tab is created, but date/time in IPTC tab have been deleted for all photos. Why?
Captions in EXIF and IPTC tab are still set to the correct values.

step 5) Proceeded again with step 3 (set date/time)
- Selected all photos
- Ctrl-I => IPTC menu =>date/time => set „EXIF taken“, write to all => close
(options selected: „keep date/time“ and “combine new and existing values => overwrite existing values“)

Caption in XMP and EXIF still have the correct value of each photo, but IPTC caption is set to the value of the first photo (test 1).

I can repeat the procedure again and again without ever getting the correct values in EXIF, IPTC and XMP.
I am a bit confused about this behaviour because I have no idea where I went wrong?

Thanks for your help
Andreas

Is nobody out there who could help me with this issue?

Again, looking forward to any helpful hint.

When you use IPTC dialog box on more than 1 files, you must use 'Clear' before, else you'll have the first iptc data on all files
