Quote:..do you think the Heal Selection that comes with this version of Resythesizer capable of working correctly on 16-bit images?
Honestly I do not know. It does comment in the resynthesizer code "no less than 16-bit by C standard" So it might just work internally at 16 bit. I do know that gmic works internally at 32 bit floating point.
Subjectively
From camera and a pair of RAW/jpeg. RAW into Gimp as 16 bit using Nufraw and jpeg 8 bit (as it is). Same selection/area/settings
Using resynthesizer/heal selection, the 16 bit image better result than the 8 bit.
Using inpaint (multi-scale) 16 bit better than 8 bit and generally inpaint better than resynthesizer.
However, all depends on the image and the eye-of-the-beholder.
