           Summary: Wish: Tool to remove Chromatic Aberration from photos
           Product: digikam
           Version: 0.9.1
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: krienke uni-koblenz de


Version:           0.9.1 (using KDE KDE 3.5.6)
Installed from:    SuSE RPMs
Compiler:          gcc 4.1.2
OS:                Linux

Many lenses suffer from chromatic aberration, eg blue color fringes that run along edges in a photo with a high contrast.

It would be nice to have a lens correction tool that can remove these effects or make them less visible.

For linux I know that bibble has such a tool. In digikam there is to my knowledge no such filter up to now.

Thanks
Rainer

Correcting chromatic aberrations would indeed be good.
The only open source tool I am aware of is fulla, see
http://hugin.sourceforge.net/tutorials/tca/en.shtml

In the end I think such a tool should (in addition) be integrated
in the full process of raw conversion, if possibly
using information about different lensese from a database
(see http://lensfun.berlios.de/)

SVN commit 797980 by cgilles:

digiKam from trunk : LensCorrection image editor plugin :

- Use right dialog to have fine editing Lens correction settings preview.
- Fix slots and signals names to be speedly read source code.
* Update preview with Lens type is changed.

Adrian:

- Now plugin is suitable as well and work properlly, but of course uncomplete.
- Bugs 143864 and 125233 will be closed when chromatic aberrations corrections will be corrected by this plugin.
- Still few camera model not supported properlly by LensFun. There is no message to gui to ping user about.
- Sometime,  LensFun device is null when a camera model is selected. Why?
- We need to improve gui to have a manual correction: for ex, lens focal must be selectable somewhere, and certainly more settings as
Apeture. We need to discut about.
- I think than a visual preview of distorsion using a grid is a excelent guide to users (like LensDistorsion plugin do)
