Appearance ========== Following Torsten Brongers calibration guide, I took Raw photos of a modern building with my Canon Powershot SX160 IS using CHDK. The TIFF files created by calibrate.py were processed with the method described in the vimeo tutorial. This way, I created my custom lensfun.xml file [2]. When opening one of the Raw photos [1] in ufraw and selecting my camera model, it is visible that the image is insufficiently undistorted[3]. Hugin however does a proper undistortion, when provided with the a, b and c parameter from lensfun.xml. By trying out some older versions of lensfun, it appeared that versions prior to January 1st 2014 were undistorted properly [4].
Commit of introduction ====================== 41fa7a (Patch #3532 Fix vignetting in case of non-matching crop factors) Details ======= The commit is missing a proper message, explaining the details of the changes. I don't see the relation between the patch title and the code changes.
