Use channel selection to quickly eliminate spots on people’s faces

Source: Zhongguancun Author: Shun Ge This tutorial introduces a very practical method of removing spots. Process: Copy the required channel, use commands such as high-contrast preservation filter and threshold to find the spots, then adjust the selection of the spots, and then use tools such as curves to brighten the spots to eliminate them.

Use the threshold tool to find spots. The method is as shown in the figure. Copy the blue channel and keep the high contrast. The radius is adjusted depending on the size of the spots, usually around 4.5.

2. Use threshold to find spots. Adjust the threshold level value appropriately while observing.

3. Keep the spots and erase the rest with a white paintbrush. (You can also skip this step. Add a mask in the fifth step and use a black brush to erase the other parts that don’t need to be adjusted, that is, the parts to be erased with a white brush.)

4. Press Ctrl with your left hand, use the mouse to click on the blue channel copy with your right hand to select the highlight area, and then invert the selection.

5. Use curve adjustment. Observe while pulling, the spots should be similar to the surrounding skin color.

6. After completing the previous step, the skin has improved qualitatively, but in order to be perfect, cosmetic microdermabrasion is still needed. You can use manual microdermabrasion or plug-in microdermabrasion, but you must control the degree of microdermabrasion and do a little more. Microdermabrasion is enough, the purpose is to further improve the skin. Finally, make some routine adjustments. The picture below is a screenshot of the process.
