The retouch module in the latest release of Dark Table is wonderful. However, all the examples I have seen are for things like faces with no fine detail in edges.
In the attached image I want to remove, or at least de-emphasise, the white patch at the front of the pelican’s neck. If you look at the patch in detail you can see the jaggedness produced by the feathers. How does one do what I want without removing that roughness?
