Some of my photos taken in bright daylight with film era lenses show purple fringing.
To remove it I have tried:
- Bibble 5, does not seem to have any way of doing this.
- I used the hue-saturation control in GIMP, but I find it tedious and ineffective.
- I found some instructions on how Darktable can be patched to include a purple defringing module from a git repository, this might work but the whole idea of patching up a test version of Darktable from git seems not all that tempting to me.
Is there any simple to install and use program that will run on Ubuntu and preferably in Bibble 5 for removing purple fringing?
