Use digiKam 1.0.0, with Batch Queue Manager.
Set you RAW in a queue, set a batch tool to convert JPEG and adjust
settings in right panel.
RAW decoding settings is common for all (at this time). Go to digiKam
setup and look if all is right for you in RAW setup.
For next release, i plan to add a dedicated Raw decoding setting for a queue.
The kipi-plugin RAW batch converter do not have a setting to adjust
