Roman, Your last patches over digiKam LensFunIface applied to current git/master (next 3.0.0 release) will fix this entry ? Gilles Caulier Gilles, Don't tnink so, this one looks different to me. Maciej, Can you provide some sample images to test here. Please host files on the web for download Thanks in advance Gilles Caulier Created attachment 76315 [details]

I've prepared short screencast illustrating what is the issue. This screencast might be watched here: http://youtu.be/pCBp3qh9ESE The screencast was prepared with the same photo set as previously uploaded. @Gilles: In reproducing this bug, what is happening on my Kubuntu 11.10 oneiric is that Lens Auto correction tool is not working at all ! Vignette correction and lens distortion is working ..any suggestions as to what can be done ? I am using digikam 3.x version on KDE 4.x.... Lens AutoCorrection is not available if at least lensfun shared lib version >= 0.2.6 is not present on your system. It's a n optional dependency. Install this lib, reconfigure with cmake, compile and install. Check at cmake config time than lensfun support is actived in cmake resume. Note : i don't yet tested compilation and runtime using last lensfun 0.2.7 Gilles Caulier @Gilles :: I am triying my best to reproduce the bug, but unfortunately lens auto-correction tool is not at all working ! Tried taking help at IRC too ! Anyways, this is my CMake output :: http://paste.kde.org/691178/ Little details:: libclapack library found................. NO (optional - internal version used instead) libimagemagick library found............. NO (optional) QtKOAuth library found................... NO (optional) All other libraries are found! Even sorted out lensfun dependency as you advised earlier :) Please guide me a little on this. Hi Gilles, I am trying my best to reproduce the bug, but unfortunately lens auto-correction tool is not at all working ! Tried taking help at IRC too ! Anyways, this is my CMake output :: http://paste.kde.org/691178/ Little details:: libclapack library found................. NO (optional - internal version used instead) libimagemagick library found............. NO (optional) QtKOAuth library found................... NO (optional) All other libraries are found! Even sorted out lensfun dependency as you advised earlier :) I presume libclapack internal dependency with digikam might be bugging which I saw in itself is another minor bug.Please guide me a little on this. --- On Mon, 2/18/13, Gilles Caulier <caulier.gilles@gmail.com> wrote: From: Gilles Caulier <caulier.gilles@gmail.com> Subject: [digikam] [Bug 303848] BQM LensCorrection tool : doesn't work when 'use metadata' option is set To: akshay_ratan@yahoo.com Date: Monday, February 18, 2013, 12:48 PM https://bugs.kde.org/show_bug.cgi?id=303848 --- Comment #8 from Gilles Caulier <caulier.gilles@gmail.com> --- Lens AutoCorrection is not available if at least lensfun shared lib version >= 0.2.6 is not present on your system.

NO (optional) ==> we don't care : there are optional dependencies for kipi-plugins not digiKam. From your trace http://paste.kde.org/691178/ all is ready to be compiled. Go to build dir and run make.... Gilles Caulier If Lensfun tool doesn't work, try to indentify why. Instead to use GUI, look my test lensfun command line progam in core/test : https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/changes/tests/testlensfuniface.cpp To compile it, turn on cmake option -DKDE4_BUILD_TESTS=on : https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/CMakeLists.txt#L1705 If you want to see debug statements on the console, run kdebugdialog and turn on digiKam, Keviv2, and others relevant debug spaces. Gilles Caulier Could this be just that when there's just a partial match, it won't proceed on BQM? What I had in mind (as I have similar problem, for some reason lensfun returns two lenses instead of the "strict" match) to save the selected lens after asking user about it. So when lensfun returns multiple matches (in my case "<lens>" and "<lens> r", allow user to save the preferred lens and use that as a default from that point. Git commit 09e5724cc30efa46314fb773be318890be1d32c4 by Gilles Caulier. Committed on 28/11/2013 at 16:10. Pushed by cgilles into branch 'master'. apply patch from Teemu Rytilahti to handle properly multiple matches of lens from lensfun REVIEW: 111021 M +32 -26 libs/dimg/filters/lens/lensfuniface.cpp http://commits.kde.org/digikam/09e5724cc30efa46314fb773be318890be1d32c4 Hi Gilles,
I've experiencing the same problem with my Sony Nex 5r + Sony SEL 35mm f/1.8 lens, in the BQM the automatic lens correction fails because it can't find the lens in lensfun. I also tried it with the editor, here also the lens isn't detected automatically. When I then select the the lens manually the correction ist applied correctly.
I'm using raw files in the BQM.
Tell me if I can help with debugging ...
(and thanx for this awesome piece of software! :-) )
I forgot: I'm using digikam 4.0.0 with lensfun 0.2.8 on debian unstable. This file still valid using digiKam 5.0.0 ? Gilles Caulier I have the same issue with digiKam 5.0.0. The lens auto-correction can't determine the subject distance (camera and lens are detected correctly) and instead of assuming default value like the image editor (i.e. 0.0) it fails completely. Is there a way to work-around this? Git commit 81dfd7dced674efdbe768413330513d29d7b94dd by Maik Qualmann. Committed on 06/07/2016 at 17:22. Pushed by mqualmann into branch 'master'. use default value for object distance when not available M +10 -12 libs/dimg/filters/lens/lensfuniface.cpp http://commits.kde.org/digikam/81dfd7dced674efdbe768413330513d29d7b94dd Not all cameras reports the subject distance. Here recommends Lensfun a value of 1000. We use now this value when missing the subject distance in the metadata. The camera from Description is not supported by Lensfun. Please report this to the Lensfun team. I close this bug now. If necessary, please reopen. Maik |
