Original picture
final renderings
1. Open the image and press Ctrl+J to copy one layer. This is a good habit.
2. Enter the channel panel, select the "green" channel, press Ctrl+A to select all, then press Ctrl+C to copy, then select the "blue" channel, and press Ctrl+V to paste.
3. Perform "Color Balance" to adjust the color of the picture (as shown in the picture). It is best to use an adjustment layer for easy modification.
4. Then execute "Curve" (as shown in the picture) to increase the brightness and layering of the picture.
5. People's faces are a little red, so you need to lower the saturation of red. Run "Hue/Saturation", select the "red" color, and then lower the saturation. (As shown in the picture)
6. Now that the final effect has been obtained, I will not go into some other picture modifications (such as text modification, softening modification).
