How does PS adjust the photos of people through the glass clearly?

We have taken many portraits, and we often hear comments praising this person for his transparent skin color and clean skin color. For example, the skin is very bright and transparent. Is it clean and flawless? Many times, playing photography will be a bit confusing, so I will try to share some methods about observing the transparency of skin color modification.

The left picture shows the original film, and the right picture shows the film. Here, we mainly solve the problems of opaque skin color, overall film gray, dark dirty and so on. So how to identify the skin color is not clean, and how to modify it later? Please continue to read the analysis and sharing below.

In fact, it was taken through a layer of glass, so the original film is gray and not even clear enough.

Firstly, the clarity, contrast and sharpening are appropriately increased in ACR. Adjust the saturation of each color in HSL. The idea and method here is to improve the saturation of people-related colors, reduce the saturation of environment-related colors, and make the color of the whole picture relatively transparent.

There is a detail here, which I have deliberately kept a little gray, that is, there is a little lack of dark color through histogram observation. Why, for beauty?

After entering PS, the focus of decoration is fine-tuning skin color, which is also the focus of this sharing.

The first thing to see is uneven skin color. If it is invisible or not obvious to the naked eye, you can also use PS to establish an observation layer to help us analyze and identify.

This time, I set a hue/saturation (red) observation layer, and pulled the red hue to the far right, so that the red hue in the picture will have a great deviation, which is convenient for us to observe the color difference of red.

Here, through the observation layer, we can see that there are still many uneven skin colors, especially in the dark. The next step of PS is to solve these problems.

Then share the methods of fine-tuning skin color and unifying skin color. There are three main steps used here: imitation of soft light layer-fine adjustment of optional color-fine adjustment of hue saturation.

Close the observation layer, create a new soft light mode layer, press alt under the brush tool, absorb the normal skin color (the color you want to imitate) and smear out the missing color and uneven skin color. The opacity and flow of the brush tool here are relatively low, about 10% and 30%.

Here you can have a look at the area I drew, mainly the uneven color under the layer I just observed.

Then fine-tune the red and yellow in the optional colors to get a relatively uniform skin color.

Next, fine-tune the saturation and lightness of red and yellow in hue/saturation to further unify skin color.

After the above three steps, under the observation layer, is the skin color much more unified, making the skin color more transparent and natural?

After closing the observation layer, the brightness/contrast was adjusted, cyan was adjusted in the optional colors, and white was fine-tuned, even without any so-called polishing.

The parameters here are adjusted according to the style, and it is not recommended to copy them. The film is as follows:
