Have you ever had hot spots (over exposed areas) on the skin that needed to be edited out in Photoshop? I’ve had this problem with hot spots many times before, and this is how I remove them.
1. Go to the clone stamp.
2. Set the blend mode to darken, set the brush opacity to around 40 percent.
3. Find a good area of skin, and then clone this onto the hot spots.
The result is pretty convincing and easy way to correct this type of lighting error in post production using Photoshop.
