There is one fantastic tool in RT, called Edges. I use it especially for birds in flight, also tried on some trees, cables etc. landscape details. It’s absolutely halo-less. Pushed too much gives “oil paint filter” effect known from GIMP. But if used reasonably, it’s worth exporting TIFF from DT to RT just to use this particular tool.
100% crops. Not used, used reasonably and pushed to max:
Is there any way to achieve something similar using DT?
Here is description and some example https://rawpedia.rawtherapee.com/Edges_and_Microcontrast , they even posted a link to (nonexisting but archived) site with open code algorithm of this filter.
