Colors matrix to process DNG is provided by libraw. Each camera as a dedicated matrix. Perhaps your camera is not in the list of supported device from libraw. Go to digiKam Help/RAW Camera support and take a look. Also let's me hear which libraw you use (look dialog info for details) Gilles Caulier Shouldn't there be some warning that the camera's RAW is unsupported? AFAIK Adobe's DNG Converter will not process unsupported RAW. We have a test application running in console to check processing : unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: DNGWriter: Raw data loaded: unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Data Size: 20181312 bytes unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Date: "2012-07-07T03:13:52" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Make: "RICOH" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Model: "GR DIGITAL 4" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- ImageSize: 3672 x 2748 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- FullSize: 3672 x 2748 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- OutputSize: 3672 x 2748 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Orientation: 0 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Top margin: 0 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Left margin: 0 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Filter: "RGGBRGGBRGGBRGGB" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Colors: 3 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- Black: 0 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- White: 4095 unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: --- CAM->XYZ: unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: "0.0000 0.0000 0.0000" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: "0.0000 0.0000 0.0000" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: "0.0000 0.0000 0.0000" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: "0.0000 0.0000 0.0000" unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: DNGWriter: DNG memory allocation and initialization unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: DNGWriter: DNG Negative structure creation unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: DNGWriter: Warning, camera XYZ Matrix is null unnamed app(3121)/KIPI (general) DNGIface::DNGWriter::convert: DNGWriter: Updating metadata to DNG Negative The matrix is null. Your camera model is not supported by libraw. I agree, this must report an error instead a warning... Anyway, if you want to see your camera supported in the future, report this problem to libraw.org project. Thanks in advance Gilles Git commit a7895789ff24a80b6fec9a9e0bacf495a53b46e5 by Gilles Caulier. Committed on 30/07/2012 at 13:12. Pushed by cgilles into branch 'master'. If Color matrix is not supported by libraw to process RAW file to DNG, report an error and cancel processing. Report error string to listview.

I reported missing camera support on LibRaw project as suggested (see http://www.libraw.org/node/1667 ) but was told that actually LibRaw supports the Ricoh. Actually it makes a lot of sense, because the Digikam editor opens Ricoh GRD4 raws without problem. Only problem is with DNG Converting. Michal, This file still valid using last kipi-plugins 4.10.0 ? Gilles Caulier The original problem (wrong colors) is gone, but now, the DNG converter will not convert the file at all with "File not supported" error message. Where did you see this message exactly ? Don't forget that plugin use libraw in background to extract RAW data from file. Libraw has 2 extensions not published in standard to handle more RAW type and more demosaicing algorithms. You must to be sure that all libraw extensions are installed on your computer. Gilles Caulier The message show in the DNG Converter window in "Status" row. I have not much idea about 2 LibRaw extensions you're talking. I have installed libraw 0.15.4 from main Ubuntu Trusty repository (libraw9 package). http://www.libraw.org/download There are 2 packs proposed as separated tarball. Please check if both are installed on your system. Gilles Caulier I think these packages are not installed, I have only this: http://packages.ubuntu.com/source/trusty/libraw New Kipi-plugins 4.11.0 is available : https://www.digikam.org/node/740 Can you reproduce the problem with this release ? Gilles Caulier The problem persist with 4.11.0. Actually DNG from new Ricoh GR Digital camera is affeced too. DNG file from Ricoh GR IV for testing can be downloaded here: http://img.photographyblog.com/reviews/ricoh_gr_digital_iv/sample_images/ricoh_gr_digital_iv_16.dng Any feedback with current AppImage bundle for Linux ? https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM Gilles Caulier |
