How to extract foreign mm hair-PS Channels

Ref: http://ps.sioe.cn/ps-koutu/4769.html

The hard part in the figure is the hair. How can the contrast between some hairs be restored?
1. Start the material and find that the hair color difference is large. Use different channels to issue the hair.

2. Check the channel. The human body and most of the hair in the blue tunnel have a big contrast with the background. You can use the blue tunnel to hide the human body and most of the hair.

3. The hair indicated by the arrow in the red channel has a large contrast with the adjacent background. Use the red channel to flat the white hair.
The idea has been fixed. Next, we will start the operation.

4. Enter the channel, copy the blue channel to get the blue copy, and press Ctrl + I to reverse.

5. CTRL + L color level, data for reference. Turn the hair on the edge to white, and the background to black.

6. Set the foreground color to white and paint the human body and hair with a paint brush. Note that do not apply the gap between the hair.

7. Click the arrow to load the blue copy to the constituency.

8. Return to the layer panel, select layer 0, and press Ctrl + J to copy Layer 1. Create a new layer above layer 0 to fill in blue as the test layer. As shown in the figure, mm is basically extracted.

9. Enter the Channel again and copy the red channel to get the red copy. Apply it with a black brush and keep only white hair on top of your head.

10. Press Ctrl + L to adjust the Color Order of the red copy for your reference. Adjust to the hair to be white and clear with the background black and white

11. Return to the layer panel, select layer 0, and press Ctrl + J to copy the Layer 3. Mm has been extracted.

12. Pull the new background and complete the work.
