This tutorial introduces some ideas and methods for removing acne on characters. Idea: The spots on the face are usually little by little. As long as we set the size of the brush, different sizes of brushes are needed for different acnes, and then absorb the color of the skin near the acne, and then directly use the brush to remove the acne spots. . The method is very simple and practical.

1. Set "Source" in the properties to "Sampling" and uncheck "Align"; the repair effect of the repair point depends on the color pixel of the sampling point, so the sampling point is generally near the repair point, so the color transition will be It is relatively smooth. During the operation, I often use radiation to repair several surrounding repair points at a sampling point, and the effect is not bad;
2. The rule of repair sequence is to "pick the weakest persimmons". First deal with the areas with better sampling points nearby. After the first cleaning, maybe those difficult and complicated problems will be new and look more like sampling points. ;
3. Sometimes the pixels of the repair point are darker or brighter than the sampling point and the original repair point. Then try another sampling point; if it is still not ideal, don’t worry, as long as the overall result is more pleasing to the eye than the original repair point. Complete; next step is to increase the diameter of the brush and set the hardness to the lowest. There is no need to change the sampling point. Click again on the same repair point and it is basically OK;
There is one more tip to mention that has nothing to do with the Healing Brush Tool. The previous operation tutorial mentioned "use the burn and dodge tools for modification." In addition to modifying lip lines, lip lines, lip highlights, eye whites, pupils, etc., these two tools can also modify areas that are too bright or too dark. The skin is treated. For example, do not use the Stamp Tool or the Healing Brush to solve some dark color blocks, and do not use violent methods such as blurring, because this will destroy the texture that should be retained in the picture. Use the Dodge Tool to set the "Midtone" and low exposure to slowly repair it. .
Check "Extended View" in the "1" drop-down triangle, and select the "Blue" channel in the "2" drop-down triangle. You can see that the number in the middle value of "3" is 76. The middle value represents the value of hue/saturation. Generally speaking, 80 is used as the scale. If it is less than 76, it is low. The values of the other two channels are normal, so the blue channel is selected for processing.
In addition, judging from the picture, the girl’s skin color is yellowish. Red + green = yellow, so if you increase the red value, there will be slightly more red components in yellow.
From this point of view we need to adjust the blue and red channels.
Open the Channel Mixer and select the blue channel.
Adjust the blue color in the source channel and pay attention to the changes in the histogram. When adjusted to 105%, the middle value of the histogram reaches 80. Just stop and have an explanation on the numbers. If you adjust it again, you won't be sure.
In the same way, go to the red channel, directly observe the preview image and adjust the red color in the source channel. When it is adjusted to 105%, it is almost ready, and then click OK.
