Description Cristian Tibirna 2010-07-10 04:21:21 UTC
Version:           1.3.0 (using KDE 4.4.4) 
OS:                Linux

The title says it all. I now have digikam 1.2 in kde 4.4.5 (compiled by openSUSE) (I tried 1.3, but it misses some library symbol and thus doesn't start).

The observed problem is that enabling auto-brightness (which is very useful with 16 bit raw files) does do auto-regulation of brightness ONLY if highlight overblowing is set on anything else but "Rebuild". If rebuild is chosen, no matter what level, images are imported darkened, brightness is not auto-regulated.

Thanks for an excellent product!

Reproducible: Always

1/ give me a NEF file to test there.

2/ give me the libkdcraw and libraw version that you use. go to Help/Component info for details

3/ enable debug trace, running kdebugdialog and selecting digikam and libkdcraw from the list. Run digikam from a console, process your NEF file, and copy and paste all messages there

Cristian,

This file still valid using digiKam 2.x serie ?

Comment 5 Cristian Tibirna 2011-12-15 14:29:29 UTC
Yes :-( And the problem also exists for "highlights=Unclip". Only "highlights=blend" and "highlights=solid white" allow for "auto brightness" to work as expected.

The .NEF attached is still useable for testing. 

Currently, my local version of digikam is 2.3.0, libkdraw is 2.0 and libraw is 0.13.5.

Thank you!

Cristian,

A lots of change have been done into libkdcraw and libraw published with digiKam 3;x serie. It will be nice to check if problem is reproducible with last digiKam 3.5.0.

Thanks in advance

Comment 7 Cristian Tibirna 2014-01-02 16:58:49 UTC
Gilles, the problem is still reproducible with digikam-4 beta 1. Exactly same details (as above).
Comment 8 caulier.gilles 2014-08-29 22:42:34 UTC
Christian,

I recommend to try to use last digiKam 4.2.0 AND last libraw 0.16.0 to see if bug still reproducible...

Comment 9 caulier.gilles 2015-05-15 22:15:14 UTC
Christian,

What's new about this file using digiKam 4.10.0 and Libraw 0.16.x ?

Comment 10 Cristian Tibirna 2015-05-16 13:03:49 UTC
Thanks for the heads up.

The reconstruction is now correct with all combinations of "highlights" and "auto brightness" (on or off).

Thanks a lot for the great work.
