These actions can be applied multiple times and they always duplicate the background layer.
Working Layer: work with brush on this layer so you can easily correct or mask mistakes and you can leave the blurred layer intact.
Surface Blur: mask in the surface blur layer for softer skin.
Two types of Frequency Separation
- Apply Image: standard technique
- High Pass Filter: more precise control, tones down highlights, high pass filter radius and blur radius must be the same.
"The Apply Image and High Pass approaches of separating frequency spatial data of an image are the two main ways of how I use the FS technique," says Aleksey, "Apply Image setup is more accurate, but the High Pass setup is quick and helps me to not only customize the separation of skin texture from underlying colors, but also tone down "hot" highlights on the skin. I always go for the High Pass setup when I need to do a quick retouch, especially when evening out skin. It is really helpful to be familiar with and practice both approaches."
