Bug 466773

The lens information is missing because Exiv2 has a problem reading the Makernotes and they are not copied correctly. Unfortunately, RawTherapee does not look at the XMP metadata in which we make a copy.
The thumbnail is a libraw conversion without "optimizations".
For the Makernotes we need to use ExifTool.

Exiv2 ( 3 ) :  Offset of directory Panasonic, entry 0x8010 is out of bounds: Offset = 0x00010fa0; truncating the entry

Maik

Hello Maik,
yes, the strange thing is that ART and darktable does not have these problems.
Unfortunately, I understand little of your comment: "Exiv2 ( 3 ) :  Offset of directory Panasonic, entry 0x8010 is out of bounds: Offset = 0x00010fa0; truncating the entry" ???

But let me ask if digiKam will change something there, or if everything will stay the same.

I am very interested in a good conversion to DNG. Switched from Windows to Manjaro Linux, and if I could do without Adobe DNG Converter over wine in the future, would be wonderful.

Currently digiKam also has problems with the size of the embedded Jpeg. They are mostly not made in original size but much smaller, unfortunately.

My question: What can I do to make digiKam better? I can't program, but I can do a lot of testing. Tell me what, I will do it.

Best regards from
Michael

Please check this DNG file created by digiKam-8.0.0 (git/master) if all is ok.

Hallo Maik,

I'm thrilled: the lens is now recognized correctly in RawTherapee. How did you do that? Can digiKam do that on its own in the future?

(Do you speak German? That would be a great help for me, not having to translate everything back and forth.
I am so excited. I am dying to do something for digiKam).

I have just tested the digiKam version 8.0.0beta1: Unfortunately still the wrong lens. I will be patient until the good version is available normally.

Yes I speak German. Here, however, English is the preferred language so that all developers can understand it. But you can write in German in a private mail.

As the changes were first added to digiKam-8.0.0 today, they not yet be available in a downloaded version. Gilles will certainly build new digiKam-8.0.0 bundles again soon, which will then be available here:

I understand, here in the forum English is the correct language. So far I can already cope with it.

I am looking forward to the new version.

Question: How reliable is it to convert your raw files to dng with digiKam? Can you delete your original raw afterwards with a clear conscience?

I'm aiming for this mainly because with digiKam I can write keywords and annotations directly into the dng. That's why I'm still using the Adobe DNG Converter at the moment. If I could replace this completely with digiKam, that would be wonderful. 

And, how can I write to you privately?

@diekuhrannte@web.de 

digiKam 8.0.0 is out. This entry still valid with this release ?

Best regards

Gilles Caulier

The problem is solved. 
Thank you.

Thanks for the feedback.
