[digiKam-users] raw edition: defalt objective not recognize

[fch22]

Hi all


I have a problem this morning when editing the raw files I just made.
(I'm using 5.8.0 on windows)

I have a camera LUMIX FZ300, and I have imported pictures into digikam.
When looking at the RW2 file from digikam it sounds correct and the JPG
too (I used RAW+JPG in my camera)

Problem comes when I'm using the editor to open the RW2 file, it is
presented with a high distorsion. So I select the automatic lens
correction menu, and I see the model proposedis FZ150.

so I select FZ200 (as it uses the same lens than FZ300) and apply it,
and now it is ok.

for information, the option "use metadata" is selected  (it indicates
partial match and model used is FZ150)

That could be ok except that I just opened another RW2 file I took 2
weeks ago with the same camera and the result is completely different
(with same option). By default, the picture doesn't show any distortion
in the editor. Only difference I notice is that in that case "automatic
lens correction " is not activated unless I click on "use default
settings",  and in that case the same model is selected (FZ150) and this
conduct to an important distortion)


so my questions are  :
- why there is a different behavior when editing 2 differents raw (taken
by the same camera), and more generally how to get a normal picytire
when opening a Raw file
- why , while  "using matadata" is selected, the model is FZ150
- how to get FZ300 model in the list and to  get it selected by default

Hope I've been clear enough, if clarification needed, I can send some
screenshot

thanks for your help

It's simple : the lens database from LensFun library take age. In fact LensFun still frozen to last stable while bundle are created : 0.3.2

I talk with Lensfun team in project forum, to have an update of the library, but sound like the code have been re-written indeed and is not yet enough mature. The problem is : 0.3.2 release date come from 2015...

There is a file in bugzilla to update the lens database independently of source code. I don't yet investigate this solution.

But you have a technical solution, already talk in this room: put the Lens database update (XML files) in your home directory (in a specific directory), and run digiKam. It will try to open files and work with it as well.

Sourceforge Lensfun project file is unavailable now, so i cannot point to the right page about the details of a local database.
