Version: 2.0.0 (using KDE 4.6.4) OS: Linux Raw file from Fuji X100 camera looks underexposed compared to their JPEG version. They show just fine under Lightroom. DNG generated by Digikam and Adobe converter don't look the same. Reproducible: Always Steps to Reproduce: When opening the following RAF file http://natzo.com/images/X100-test.RAF ...coming from a Fuji X100 under Digikam image editor I notice a grey cast on the picture, like underexposed. It looks like this: http://natzo.com/images/X100-test_under-image-editor.jpg If I open the same RAF file under Lightroom I see something like that: http://natzo.com/images/X100-test_UnderLightroom.JPG I then converted the RAF to DNG file using DigiKam's built-in RAW converter but the underexposure is still there (Digikam image editor) even if I open the genereated DNG under Lightroom. Here is the DNG from Digikam: http://natzo.com/images/X100-test_fromDigikamconverter.dng Now if I convert the RAF file using Adobe DNG converter it will look just fine under Lightroom but underexposed under Digikam. Here is the DNG from Adobe: http://natzo.com/images/X100-test_fromAdobeDNGconverter.dng Is this a normal behavior? None of the RAF files match the corresponding JPEG as far as exposure. Expected Results: RAF picture opened under image editor should show correct exposure. DNG conversion should show correct exposure too.
which libraw you use. go to help/components info for details gilles caulier
It looks like auto-brigtnes magic in LibRaw has fooled by large overexposed window. You need to adjust image brightness and/or exposure correction manually. Also, camera white-balance is fooled too, the image is too blue. You need to warm your picture by adjusting WB settings.

I'm puzzled by the fact that DNG files generated by DigiKam look underexposed under Lightroom where DNG files generated by Adobe converter look fine under Lightroom.
Dany, Do you see Alex comment #2 ? Gilles Caulier
Dany, With last digiKam 2.5.0, Fuji X100 and Fuji X10 raw file work fine into digiKam. I'm sure i use a X10 camera here... Gilles Caulier
Dany, We need a fresh feedback here, using last digiKam 4.2.0. Gilles Caulier
Tried with 4.2.0 and everything looks fine.
