Easy to understand the high and low frequency repair diagram example: The author of the high-frequency groping very thoroughly, many details of the processing is worth learning.
High-frequency in fact very early in the foreign people in use, later I after years of improvement has a better way. High-frequency is not used to grind skin but to mix color and light. The high and low frequency principle divides an image into two layers. One is the color light brightness layer The second is the texture layer, so that we can repair the color brightness and light without affecting the texture. Fix the texture without changing the color.

Final effect
1, on the original image of the copy of the two-level shortcut key ctrl+j. Name the first layer of the color layer (this layer retains the color brightness light and shade) The second layer is named the texture layer (this layer retains the texture).
2, the color layer of Gaussian blur, blurred to see pores (note: The more blurred the more rough texture. Less fuzzy, easy to fine. The blur is rarely repaired.
3, the third step to the texture layer application of image layer Select the layer you just blurred mixed to subtract the scaling 2 compensation value of 128.
4, then change the pattern of the texture layer to linear light.
