I want to develop raw images from an Olympus Pen series camera using digiKam. I have observed, that the standard output of digiKam, i.e. without any adjustments of the parameters, is different from that of the image viewer gwenview. While the gwenview output is almost not distinguishable from the in-camera jpeg, digiKam requires a lot of adjustments to achieve the same result. Since both programs rely on the same library, is there a simple way, to achieve the gwenview result in digiKam?

I think i understand what is happening. Gwenview does not show the Raw data, but rather a jpeg preview that is embedded in the raw file.
