In file "compact-panasonic.xml" the entry Panasonic DMC-LX100 panasonicDMCLX100 2.21 Points to: panasonicDMCLX100 Add a new -File (or edit in compact-leica.xml?). Copy model "DMC-LX100" as model "Leica D-Lux typ 109" into the new file. Copy panasonicDMCLX100 into the new file. The model must match exactly the text from the exif-Data. Your changes will be erased with the next update of lensfun. Make a copy. If it works, give a ticket to the lensfun-projekt. For a while the name of my new mft-lens did not match excatly between lensfun-data and exif-data. Editing this files helped my using lens-correction in darktable until the error was fixed in lensfun.

What you could try: - copy /usr/share/lensfun/v1/compact-panasonic.xml to ~/.local/share/lensfun/v1 (under a new name) - edit that copy to include the proper camera and change the lens name "DMC-LX100" to whatever your camera reports. - save the edits, and (re)start darktable or see http://lensfun.sourceforge.net/calibration-tutorial/lens-calibration.html disclaimer: the above is a summary of what has been reported in this list in earlier threads, I never needed to try this. That said, if things go pear- shaped, delete the copy in ~/.local/share/lensfun/v1 and you should be back where you started. An alternative would be to create your own correction profile using Hugin. E.g. http://hugin.sourceforge.net/tutorials/calibration/en.shtml describes how to do this (take care when collecting the images you need!).

[darktable-user] Leica D-Lux typ 109, lens correction
Hello All, this small camera needs a strong lens correction: while out-of-camera JPGs are fairly correct, the RAW files are appalling. The Lens Correction menu says "lens not found". Is there a way to trick DT to use Panasonic's LX100 lens correction, if available, since it should be in many ways a clone? thanks for your attention, -Gian darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
