metadata lost when decoding a raw file

[Robert Zeller]

Hello,

I am running digikam 1.7 and exiv2  0.21. When I am decoding a raw file
in certain cases I am loosing the metadate from the Nikon .nef raw. This
behavior is obviously related to the settings of the Color Management
parameters in the "Raw import" window:
My workspace settings is "Adobe RGB" consistent with the camera workspace;
the default settings in the raw-import window for Camera Profile is
"None" : in this case all metadata is lost in the new file during decoding.

If I set "Camera Profile" to "Embedded" then the metadata are preserved
during decoding ; also when I click on "Use Default" at the bottom of
the window, metadata are preserved.

Unfortunately every time when opening a new raw file with the editor the
"Camera Profile" setting in "Color Management" is switched automatically
to "None" again, which means that metadata get not transferred to the
produced file.

Is there a way to change the  settings such that Camera Profile =
"Embedded"  is opened by default? Which are the Color Management
settings when I click on "Use default" in the raw import window?

Thanks for advice.

Robert

I can confirm this behaviour: no metadata are transferred to the decoded image
when not using the 'use default' button.

In itself losing the EXIF info wouldn't be all that much of a problem
(although it worked correctly in previous versions of Digikam...), but it
means that e.g. the automatic lens correction won't be able to use metadata
(since they are not imported).

I can reproduce the problem here.

I found the problem but it's not yet fixed. It's due to my last
changes in RAW Import tool introduced by 1.7.0.

Please open a file in Bugzilla about this subject, i will fix it.

Thanks in advance

This bug is fixed now in SVN. Thank you, Gilles, for fixing it so quickly.

Is there any possibility of getting a new version (1.7.0?) out, so those that
depend on distributions have a chance of getting the correction before 2.0?

regards,

Remco
