           Summary: Lens Autocorrection overcompensates distortion
           Product: digikam
           Version: 2.1.1
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Image Editor
        AssignedTo: digikam-devel at kde.org
        ReportedBy: 202020 at gmx.net


Version:           2.1.1 (using KDE 4.7.1) 
OS:                Linux

Enhance > Lens > Autocorrection overcompensates distortions.


Reproducible: Always

Steps to Reproduce:
start showfoto with any image which has exif data.
The same problem when you enter parameters manually.

Actual Results:  
Barrel distortion becomes pincushion distortion

Expected Results:  
Barrel distortion should become straight grid

If you change in lensfun/slr-nikon.xml (I assume that would hold for any other
parameter file) the cropfactor for all lenses from 1.5 to 1.0 and keep the
original cropfactor for the camera description, then there is no
overcompensation and the expected result is delivered.
