This tutorial introduces the whitening and beautification of people's photos. The idea is: first use stamps and other tools to clean up the people's faces, then adjust the curves and other color correction tools to whiten the people, then use the highlight selection to whiten again, and finally add cheeks. Red completes the final effect.
1. Open the original image and press Ctrl + J to copy one layer.
2. Magnify the image and use the repair tool to repair the bad floating skin on the face.
3. Press Ctrl + J and simply adjust the curve, input 108 and output 176. The parameters are for reference only, and the skin color is normal.
!--Page break--> 4. Add an adjustment curve layer to accurately adjust the skin color. The parameters are as shown in Figure 1.
5. Add a color balance adjustment layer, midtones: -18.3.33; highlights: 8, -2, 7.
6. Cut out the background, feather it by 5 pixels, and apply an appropriate Gaussian blur.
7. Create a new layer and press Ctrl + Shift + Alt + E to stamp the layer.
8. Duplicate the layer, change the blending mode to "Overlay", and change the layer opacity to: 50%
9. Press Ctrl + Shift + ~ to bring up the highlight selection, feather it by 2 pixels, create a new layer, fill it with white, and set the opacity to 32%
10. Use the Lasso tool to feather a 20-pixel fill color (255, 214, 214) in the appropriate selection on the face, reduce the transparency, and add blush to MM.
