Now I think of it, there is another faux-polarizer type kludge which I sometimes use on shiny skin in portraits. African skin is different from European, and can really shine up, which is not a good thing. In the old days of film, a polarizer would help mitigate and is still the best solution for digital, but absent a polarizer in Lightroom I do the following:
- Use the brush to select the offending area, usually the nose or forehead.
- Reduce brightness slightly, and then apply a little negative clarity.
As always, don't over-do it. Less is more.
