Retouching is one of those things as a photographer that allows us to finish our your work with a nice polished look!
The only problem is that process can take forever until NOW.
I discovered Portraiture a few years ago and it has tremendously helped my post production work flow. It pretty much does most of the work for you as it relates to skin clean up without looking over retouched.
Here is a quick sample without doing anything. I normally perform small corrections but this software by Imagenomic does the heave lifting!
