The material is a sister paper with freckles on her face. Want beauty? Of course, let's start with freckle. After opening the material, check the channel first, and then select the channel with large contrast.
Duplicate a layer of blue channel, and execute filter-Other-Gao Fancha reservation in the blue channel, with the value of 9.
Then paint the background gray, and then wipe off your mouth and eyes with an eraser. (not scary)
Then carry out image-calculation, set parameters as shown in the figure, and then repeat for three times to get ALPHA3.
Then hold down the ctrl key, click ALPHA3, press ctrl+shift+i to cancel the selection, and then return to the layer to adjust the curve, as shown in the figure.
Then press ctrl+shift+alt+e to stamp the layer, copy the background layer twice, and move the two copies to the top.
Hide the layer outside the background copy, and execute: Filter-Blur-Surface Blur, as shown in the figure, and change its opacity to 65%.
Then click background copy 2 and execute: image-application layer. Parameter settings are shown in the figure.
Then execute: Filter-Other-Gao Fancha Reservation. Set the radius to 0.6, and then change the layer mode to linear light.
Then hold down the shift key, select Layer 2, Background Copy, and Background Copy 2, and then press the shortcut key ctrl+g to form a group, as shown in the figure, and then create a black mask.
Select the brush tool, the opacity is 85%, the flow is 100%, the foreground color is white, and the background color is black. When smeared on the skin, textured skin appears and spots disappear.
Then poke the layer to get layer 3, and execute: Filter-Sharpen-Smart Sharpen. The parameters are shown in the figure. Then save it, as shown in the figure below.
Finally, if you think there are still flaws, repeat the above operations, or repair them with a stain repair tool, and finally adjust the color of the portrait.
