Version: (using KDE 4.3.2) OS: Linux Installed from: Mandriva RPMs Dear developers I have observed an important issue with the color management of digikam with jpg photos. Here is the problem (see also attached files) When I preview an image, I get two versions, one blueish and one with normal colors (at least on my screen, which is calibrated and profile applied with xcalib) When I edit the photo (F4) I get a warning that the embedded color profile and the working color profile are not the same. If I do not convert it, I still have a blueish photo. If I convert it I do get the right colors. But the issue is that the embedded color profile and the working color profile are exactly the same (here is a copy-paste of the profiles when I click on info) Embedded color profile File name: (ICC Color Profile Information) >>> Header <<< Rendering Intent : Perceptual Profile Version : 34603008 Profile ID : 0 Name : IEC 61966-2.1 Default RGB colour space - sRGB Model : IEC 61966-2.1 Default RGB colour space - sRGB Manufacturer : IEC http://www.iec.ch Information : sRGB IEC61966-2.1 Copyright (c) 1998 Hewlett-Packard Company WhitePoint : D65 (daylight) Device Class : Display device Description : sRGB IEC61966-2.1 Copyright : Copyright (c) 1998 Hewlett-Packard Company Connection Space : Unknown Color Space : RGB CMM Flags : 0 Working color profile File name: (ICC Color Profile Information) >>> Header <<< Rendering Intent : Perceptual Profile Version : 34603008 Profile ID : 0 Name : IEC 61966-2.1 Default RGB colour space - sRGB Model : IEC 61966-2.1 Default RGB colour space - sRGB Manufacturer : IEC http://www.iec.ch Information : sRGB IEC61966-2.1 Copyright (c) 1998 Hewlett-Packard Company WhitePoint : D65 (daylight) Device Class : Display device Description : sRGB IEC61966-2.1 Copyright : Copyright (c) 1998 Hewlett-Packard Company Connection Space : Unknown Color Space : RGB CMM Flags : 0 Thank you Alex

Which digiKam version you use. Try 1.1.0... Gilles Caulier
Sorry, I used digikam 1.0.0 will try 1.1.0 and keep you informed
Please give us the affected photo. Was it edited with an older digikam version, about one year ago?
I was unable to compile 1.1.0 version to check, but here is the original photo that I uploaded Yes it was created with an older version of digikam, since the photo is dated from Nov 2008

Comment on attachment 40776 [details] Original photo with issue This is a photo which I saved the profile with digikam 1.0.0
The embedded profile is "sRGB Whitepoint: D50". This is probably wrong and creates the bluish colors - D65 is normal. You can see that the circle in the CIE Tongue is at a different place than for normal images. It's probably digikam's fault because such a wrong profile has been shipped with certain older versions of libkdcraw. There is a command line solution with exivtool available IIRC simply to strip off the wrong profile.
Thank's this is compatible with the fact that almost ALL my photos need to change their color profile :-( But, when I look at the embedded profile, it give me D65 not D50, so maybe that's why I did not found the problem before. Is it a bug of version 1.0.0 ?
Don't know if there was a problem in 1.0. Maybe. I can confirm that the profile shown in the right side bar here is D50. I close this bug report now. Have you found the right command to fix your photos? It was discussed on digikam-user IIRC and involved exiftool. The imagemagick solution was not the way to go.
