I'm trying to find a relatively quick, easy and consistent method to "artify" renders by using GIMP / GMIC filters.
One method that produced results that I very much like is centered around the "MorphologyPainting" filter in GMIC.
But there's a problem...
As you can see in the example image, MorphologyPainting (and the filter it is based on: "Painting") tend to produce a "halo" effect in areas of high colour contrast... here most noticable around her head. (And that's a weak example here)
I like the high-contrast "paintings" that this filter produces, and that the alternative GMIC "Brushify" or GIMP's "Waterpixels" do not give. But this high-contrast output also means that I cannot simply replace the offending halo-parts with inserts of any other variant.
Even rendering and filtering fore- and backgroud seperately - possible with renders, but not when this method is to be used on normal photos - doesn't provide an option, because the "normalizing" the filter uses - and which is necessary to keep colour consistency - changes the colour tone based on the average colour / brightness of the input images.
So, long story short: does anyone have an idea of how to use this filter and solve the problem? Or can offer an alternative filter that produces comparable results?
(Addendum: the method used for all three image consists of the artistic filter for the base, a high pass layer to bring back some of the details and a GMIC "sketch" filter layer for the texture. More detailed infos on request)
