this module is useful for selective skin retouching in the sense of pat david's classic article for gimp. it uses a wavelet decomposition and lets you remove detail at each scale separately, constrained to a drawn mask.
for your convenience, there is the retouch.pst preset to add both a
wavelet:retouch and a draw:retouch module with connections to the default
pipeline (assuming colour:01 is connected to filmcurv:01 and inserting the
wavelets in between).
