[Digikam-users] color cast in extreme highlights in DNG files

[Gilles Caulier]

Dou you use RAW import tool for image editor ?

There are some options to wrap around this problem...

Which libraw and libkdcraw you use exactly ? Go to Help/Components
Info for details.

I'm waiting your DNG image to test there...
