Arnd, my question here is, if this fulla integration is really necessary since all these correction are already covered by the new plugin based on the Create project using a database. As far as I understand it, fulla is not linked to a DB, so it will always be very difficult or at least tedious to make corrections with fulla, as it is difficult with the current vignetting plugin.

I would believe that this effort should be spent on a tool that supports lens calibration to deed the database.

Which plugin are you referrring to?
This sounds like the right one to use then!
(I did not follow all the discussion ion the create mailing list,
as I only subscribed recently ...)
Or are you referring to Adrians recent contribution for the 0.10?

In the end, one would like to have a tool
which does the corrections automatically (*maybe* with
the possibility of manual tweaking).

OK, then all is there, apart from the problems discussed in STATUS.
So this does not give a good GSoC project (at least
not for digikam), but should be dealt with by the lensfun people
directly.

Thanks for the clarification,

Arnd
