I like Darktable, but for the life of me I cannot figure out how to get defringe working. It's completely intuitive in lightroom and rawtherapee, but for some reason darktable just doesn't do what I want.
Thanks, yeah I think I've tried the first 2 methods. I'm expecting something like an eyedropper to come up where I click the fringing, but I think it's something else I need to do.
