Here is a little trick I learned recently from another discussion forum (a Chinese forum) to add a nice glow to the face and skin, assuming you are using Photoshop:Originally Posted by Pose
1. Duplicate the background layer.
2. Select only the duplicated layer to work on. Filter/Blur/Gaussian Blur. Set Radius to 5 (or try other values).
3. Within the Layers palette in the lefthand dropdown menu, change "normal" (default) to either "overlay" or "softlight". Also change the opacity value (right hand dropdown menu) to between 50% and 75%.
4. Merge the two layers together. That's all and have fun.
Note: Of course the value settings mentioned above are not carved in stone. Experiment to get the best results.
