On this video tutorial photographer Glyn Dewis shows how to use Hue/Saturation Adjustment Layer to reduce skin reddening in Photoshop.
Dewis start by showing how easy it is (on some pictures) to just change one specific color by using a Hue/Saturation Adjustment Layer and playing with a specific color (however there might be many images where this approach will not work if the color you want to change exist in places where you would not want to change it).
The method itself is really simple – you can use the two bars below and move them until you choose just the reds (after choosing the reds) than you bring up the opposite color – cayenne.
If there are areas that were wrongly effected – you can use a black brush on the adjustment layer that you created and remove the effect from this area – which resolve the problem that we mentioned before – really simple!
