The coming soon bulk options look like that may be something to invest in.
The idea behind human-aided definition of light and dark areas sounds promising. Many software features for removing shadows and highlights seems mostly automatic, even in expensive software.
I am digging this, thanks for the share, as because of the above noted, I am often having to do manual editing for awhile after basic de-lighting (boundaries seem to be a hassle for most these generators). Since I'm not making too many, and they often have specific uses, this will be nice.
