I would like to give you a detailed analysis of photoshop software and share with you the post-tutorial on skin polishing using a hyperbolic curve.
Tutorial sharing:
Material:
Step 1: Use a patch brush to clear conspicuous flaws on the model's face
Use a paint brush or seal tool to clean up the face's concave and convex points and conspicuous flaws
Step 2: perform hyperbolic skin polishing on the model face
Hyperbolic skin polishing: Select the highlights and shadow areas of the screen skin, and adjust the exposure using curve tools.
Step 2 key points: hyperbolic skin polishing principle
The core principle of hyperbolic skin polishing is to use the brightening curve and pressing the dark curve to highlight and press the uneven skin area in the dark screen. The first thing to mention is the observer concept.
The Observer is a tool used only to observe image characteristics without affecting the final image quality. You can add gradient ING, black and white, and curve adjustment layers on the image to form a simple observer. The role of the observer is to highlight the characteristics of the image to the maximum extent, even if the parameter is extreme, it does not affect the final image quality. We can see the image shown in the figure below in the pre-polishing viewer, which highlights the uneven skin of the figures on the screen.
After finding out the areas where the skin color is uneven, we use a mask to highlight the original dark spot area at. The same operation is performed on the dark curve, hide the highlighted area. It takes a lot of time to erase the mask.

Step 3: adjust the overall screen exposure with a curve
Adjust the overall exposure of the screen to make the dark area of the skin better.

Step 4: repair obvious defects in the arm skin

Step 5: Use neutral gray layer to repair image details
In the overlay or softening mode, the neutral gray layer can adjust the brightness and other details of the local area of the image without affecting the original painting quality. The overlay mode eliminates the features of the neutral gray, only the layer change operation is retained.
To use a neutral gray layer, follow these steps:
1. Create a new layer and fill it with color #808080.
2. Set the layer fusion mode to soft or stacked.
3. Subtract, deepen, or paint from the neutral gray layer. The operation result is directly reflected in the original image. At this time, you can directly see the original image and adjust the area as needed.

Use a neutral gray layer in soft-light mode to deepen the shadow of the model skin
Step 6: implement color separation using gradient ing
Gradient ing allows you to easily map pixel regions with a certain brightness to a specified color. According to the settings shown in the following figure, the gradient ing result is displayed with a "dark purple, bright orange" pattern. The filter color fusion mode is used to restore the bright part of the screen, leaving a purple color in the dark area of the screen, while the skin in the bright area of the face is orange, thus realizing the color separation. Finally, adjust the opacity to control the degree of partial color.

Step 7: Use a liquefaction tool to adjust the body line
Adjust the elbow and shoulder position using the liquefaction tool
Step 8: fine-tune the color sequence for enhanced comparison
Fine-tune the color order to enhance the image contrast
Step 9: adjust the light and shade of the arm and shoulder
Adjust the highlight area of the arm and shoulder to enhance the highlight effect. Tools used: curve + mask, neutral gray layer
Step 10: adjust the color of the full graph (top)
Use the curve tool to adjust the tone to make the character tone more unified
The red and green curves increase slightly, but the blue curves do not change much.

Step 10: adjust the color of the full graph (lower)
Adjust using the color saturation tool
The color saturation tool is used to make red more saturated and bright.

Step 1: sharpen with high contrast
The USM sharpen tool provided by PS is the most commonly used sharpen tool for normal people. However, portrait photographers should note that using USM sharpen will damage the image quality. the high contrast retention sharpening method uses a high contrast retention tool to extract the part of the screen that needs to be sharpened. The layer mode is used to overlay the part that needs to be sharpened, so that the contrast increases and the screen is clearer, to sharpen the image.
Sharpen steps:
1. Copy the original image to form a new layer.
2. Retain the contrast of the new layer. The radius parameter is set to retain only the texture of the image.
3. Set the new layer fusion mode to overlay.

Just look at the high contrast to retain the layer, you can barely see the skin texture.

Final result comparison
All right, the above information is the detailed analysis and sharing of all the content by using the post-tutorial of hyperbola polishing for users of photoshop, you can see the software users here. I believe that you are now very clear about the post-image repair method, so all the users will go and follow the methods shared above to sharpen the skin and try the effect.
