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) CCMAIL: adrian@suse.de BUG: 98651 CCBUGS: 143864 CCBUGS: 125233 M +58 -61 imageeffect_lenscorrection.cpp M +2 -2 imageeffect_lenscorrection.h M +43 -41 klensfun.cpp M +12 -10 klensfun.h WebSVN link: http://websvn.kde.org/?view=rev&revision=797980
Chomatic Aberation is already implemented in LensFun based image plugin. I close this file now. Gilles Caulier
