Hi, I'm having a problem with the lens correction module where more than one lens in the database matches the exif data. The GUI gives a menu to choose between the different matches but the correction data used is always the same. When a lens is chosen from the menu only its name is saved into th

hi, i would agree that this looks like a bug in the markesteijn algorithm. another thing to try is probably the green equilibration thing that some bayer sensors suffered from. that there was some spill from blue -> one green and red-> the other green (same line of the sensor, maybe during readout
