Color management

Post by Armas »

There is a bug in color profile management
(JPEG/Tiff write option: maintain ICC profile):
Correct profile embedding only in connection with batch processing.
Normal "Save" and "Save as" however embed the user-defined monitor profile or no profile at all.

Bonjour Pierre,

i hope, i can explain it with some screenshots (german user interface):

1. XnViewMP color profile settings
1_cp-settings.jpg
2. You have a photo with embedded color profile (sRGB IEC61966-2.1)
3. jpg write settings: maintain ICC profile
2_write-settings.jpg
4. As "save-as" result you have a photo with embedded user defined monitor profile (Acer...), that's not correct

5. The same photo in batch process, option: apply color profile

6. Result is the correctly embedded original color profile

yes, when opening a photo the color profile is always converted (if setting on), so when you save, the new color profile is used.

Thanks for the answer, but I don't know if you understood me correctly.
I think the setting "General - Colour profile" concerns the user's monitor profile (For Display...), or am I wrong?
However, the monitor colour profile should never be embedded in a photo. Otherwise the display on another monitor would be wrong.
And why the saving is correct in batch mode (original profile) and different in normal saving (monitor profile).
Maybe you can explain this.

I became aware of the problem through the page http://fotovideotec.de/cms_tauglichkeit/
