Which application are you using in Linux to view and process the DNG-images?
- Gimp refused to deal with the application
- Rawstudio as well (shows red colored rudimentary image only).
Currently in Linux I can only use Eclipse document viewer to view Fcam DNG picture and to save it as TIFF, but this is no RAW processing.

Which application are you using in the N900 itself to view and process the DNG-images?
Currently in Linux I can only use Eclipse document viewer to only view Fcam DNG picture.
