step:
1. This picture is seriously yellowish. It can be seen from the channel that the blue channel has almost no useful information.
It's almost impossible to restore this picture, so we try our best to beautify it
2. Since the blue channel has no information, we have to use the green channel instead of the blue channel.
The shortcut key "ctrl+2" puts the green channel into editing state (in CS4, the shortcut key is "ctrl+4". Of course, you can also click the green channel with the left mouse button)
"ctrl+A" select all, "ctrl+C" copy
Then "ctrl+3" puts the blue channel in editing mode, and "ctrl+V" copies and pastes the green channel information into the blue channel.
3. You can see that after copying the pass, the character’s skin color becomes dark magenta.
Generally, skin color tends to be orange or yellow with a bit of red.
The color of the background also looks darker, so I need to slowly adjust the color later.
4. Add a "Color Balance" adjustment layer and lower the magenta [midtones: 0, +18, +7. The values are for reference only. The values in brackets below are for reference. You can try it according to your actual situation.]
5. Add a "Curves" adjustment layer to brighten the dark areas.
6. Add an "optional color" adjustment layer, focus on the red part of the skin color, turn it yellow and brighten, and bring it closer to the normal skin color [+14, -10, +30, -40]
7. In this way, the color has been partially improved, but it still does not appear bright enough.
8. Create a new blank layer, "ctrl+alt+shift+E" to stamp the visible layer
"ctrl+A" select all, "ctrl+C" copy
"ctrl+N" create a new document and change the "color mode" to "LAB color"
"ctrl+V" paste
In the new document, add a "Levels" adjustment layer
Pull the small triangle in the middle of the "Brightness" channel to the left (or enter the required number in the number box below) to brighten the screen [Brightness: 13, 1.45, 243]
In the "a" and "b" channels, pull the small triangles on both sides toward the middle to make the color brighter [a: 40, 1.01, 215; b: 50, 1.01, 205]
Stamp the visible layer, then copy and paste it into the original "RGB Color" mode document
