           Summary: Wish: Interactive chromatic aberration correction in
                    digiKam image editor
           Product: digikam
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: plores at telefonica.net


Version:            (using KDE 4.3.3)
OS:                Linux
Installed from:    openSUSE RPMs

digiKam now uses liblensfun to implement chromatic aberration correction
(although not all Linux distros have digiKam compiled with it). But sometimes,
especially for less knowledgeable users (like me :-)), it may be difficult to
find the suitable correction coefficients for a given lens, not to mention that
this must be done with each new lens (one which is not included in the lens
database), at several focal lengths, to allow lensfun to interpolate between
them. On the other hand, making the correction directly with the Raw Import
Tool is a bit tricky and slow, as the raw file must be demosaiced each time the
red and/or blue aberration parameters are changed.

It seems to me that for many users it would be very useful and easier to use
the implementation of interactive chromatic aberration correction in the Image
Editor, much in the same way many other raw processing software do (including
those that come with many camera brands).
