How does PS refine photos?

Let's first repair the obvious defects on the character's skin, such as acne and acne marks.

The second step is to copy two layers continuously. The first copy layer name and the second copy layer name are changed to high frequency.

The third step is to copy two layers continuously. The name of the first replication layer is changed to low frequency, and the name of the second replication layer is changed to high frequency.

Step 4: Poke the layer (CTRL+SHIFT+ALT+E) and find the CameraRaw filter in the filter (note that the PSCC version can be found in the filter, and CS6 needs to be set in Edit, Preferences and CameraRaw).

Step 5: Stamp the layer (CTRL+SHIFT+ALT+E), find the CameraRaw filter in the filter and set it.

Step 6: Stamp the layer again, use the dodge tool, set the exposure to 30, 50, and use it to add the highlights of the people's eyes and polish the white parts.

Step 7: Select the lip part with the pen tool, give the feathering value 1, 2, copy (CTRL+J) and give a hue saturation (CTRL+U), tick the pop-up hue saturation window to color, and then increase the saturation of red appropriately.

Step 8: Decorate the eyebrows, create a new layer, switch to the brush tool, and press F5 in the brush tool to display the brush preset settings, as shown below.

After the ninth step is set, draw the missing eyebrows with a brush.

Step 10: Use two directions to add shadows and highlights of people. One curve is dimmed, this curve is used to add shadows, and the other curve is used to highlight.

The last step is to save the last export.
