Re: [darktable-user] Is there a repo for the newest lensfun-database?

[Jean-Luc CECCOLI]

Hello,

 

If I'm allowed, let me add... You *must*

- remove the 1st line

- remove everything following "lensfun" but the closing ">"

- replace every double linefeed (\n\n) with a single one

- be aware that your lens isn't the last in the file, or it will be ignored.

That said, I am very happy my Nikkon 70-200 vrII can now be corrected !

Maybe will I be able to work on my 500 Reflex, but I first need to print a A3 
target with straight lines, not distorted !

 

Regards,

 

J.-Luc

It works now more or less at first sight with the newer lenses. I start
a new thread re

Is it possible to configure "alias lenses"

As there are changes when I use it in dt, I didn't remove 'version="2",
I even don't know where / how I have to do this.

This is the culprit. Just get rid of this line and lensfun 0.2.8 works ok.

So --- to all listening to this --- remove the lensfun 0.3.2 hack I 
suggested before asap. It's dangerous.


One thousand thanks to jys (junkyardspar...@yepmail.net) and Roman 
(lebedev...@gmail.com) for help.


So in my case, to summarize: I added the relevant camera/lens XML 
stanzas from the new lensfun database in a file in 
$HOME/.local/share/lensfun/extrastuff.xml, and removed the "version=2" 
in  tag and all ... stuff.


And now it works with stock DT!

My step 1 and 2 are done for this camera:

1 - lens geometry correction (this)
2 - noise profiled ok ( see https://redmine.darktable.org/issues/11627 )
3 - white balance presets --- I am stuck (see 
https://redmine.darktable.org/issues/11628 ), could use help

4 - lens vignetting... will start this weekend, I hope.

If anyone can help for 3 and 4 (and some developer comment on 2, I think 
it's ok, but I can be wrong) --- chime in.

Re: [darktable-user] Is there a repo for the newest lensfun-database?

[Romano Giannetti]

Hi all,


That is *really* bad advice.
Lensfun has broken their ABI in <= 0.3.2, without bumping the API version.
So doing that will result in all kinds of subtle bugs, like
https://redmine.darktable.org/issues/11626#note-10 and so on...
I think Roman is right here. There are subtle problem (the most 
important one is that it seems that some lens correction defaults to a 
thorby-fisheye type, giving funny but horribly wrong results.


So the problem is why sometime the new database entry are not working 
for 0.2.8. For example, the entry below seems correct (and it is 
correctly selected with the 0.3.2 hack, albeit with the fisheye problem 
above --- switch to rectilinear and it works), but darktable refuses to 
let me select it with the 0.2.8:

Correction parameters depend on the crop factor, easiest to just use the 
camera body to store that, and not expect the average user to enter the crop 
factor (most will know what body they use, but probably can't be bothered to 
figure out what a crop factor is, let alone which one applies to their camera).
Also, the camera body used could help limit the number of possible lenses: 
lens IDs are not unique between brands, Canon/Nikon/Tamron/Sigma/... can use a 
given ID value for wildly different lenses. I don't think any program uses that 
info though, and its use is complicated when adapters are used.

But, unless lensfun changed the database format, there is no reason to upgrade 
the lensfun *library* only to get access to data for a new camera/lens. As 
described by Roman, grabbing the latest database files and installing them 
under your home directory should work just fine (again, if the database format 
didn't change). And it's easy to correct if it doesn't work (contrary to a 
library upgrade, which can be a pain to undo)

All that really matters is that you select a camera with exactly the same crop 
factor as the one actually used, so usually anything known to use the same 
sensor will work.

I assumed that should work, but it appeared not to in the other person's case. 
I'm not sure what the best approach is in this situation.

Simply, the old version doesn't support my lenses.

After I switched back, the distortion remained until I deleted the lens
calibration, so I "packed" the history and activated the lens
calibration again. Then it was ok.

In the meantime I know, why 0.3.2 didn't work sometimes, I use
different cameras and one was the new Pentax KP, which is not supported
until now. When I assigned a Pentax K3 instead, it worked generally.
Probably not a good idea. I don't understand why the camera is needed

Interesting question. I am back to 0.2.8-3pmjdebruijn2~xenial and hope
a new version is coming officially.

I didn't try it until now. Does it make sense to mix it with 0.2.8?

Thanks Romano,

Xenial is my system, so it looks good. The minor problem at the

the website.


Yep, there is a problem with character encoding...

This is the list of commands I did:

   sudo apt-get build-dep liblensfun0


This installed for me doxygen libclang1-3.6 libllvm3.6v5 libobjc-5-dev

   sudo dpkg -r --force-all liblensfun0 liblensfun-data


download source from  from https://sourceforge.net/projects/lensfun/files/

   tar xvzf lensfun-0.3.2.tar.gz
   cd lensfun-0.3.2
   mkdir cmake_build
   cd cmake_build
   cmake -DCPACK_BINARY_DEB:BOOL=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr ../
   make
   make package


: sudo lensfun-update-data did not work, but seems to me that it is not 
necessary now --- probably it is not installing the python libraries, do 
not know why, I am investigating. Then as root:


   cd /usr/lib/
   rm iblensfun.so.0
   ln -s x86_64-linux-gnu/liblensfun.so.0.3.2 liblensfun.so.0


Notice however that this is a hack. The liblensfun source 0.3.2 install 
itself as `liblensfun1`, although the version of the library seems to be 
0; that means that the darktable PPA will complain that the liblensfun0, 
fro which it depends, is broken.


I am not sure on how to solve this short of compiling everything from 
source. I hope the author of the PPA is listening and have a bit of time 
to help solve correctly all this mess...

apt-get build-dep liblensfun0

Which means I have to install some src-repos, because they are missing,

Which did you install please?
