Just looking for the "monkey" material map, there are usually three ways to use the method of drawing:

1 The use of filter plug-ins, Knockout 2.0. The advantage of this plugin is that it is faster to pull down and less hair loss.

2) Channel pull graph method.

3) Pull out the drawing method.

After thinking, we began the journey of experimentation.

Scheme one: According to the custom, I first use the "Filter plugin ~knockout 2.0".

First double-click the layer to unlock, and then use the plug-in to pull the map, reasonable selection of the inner and outer ring range:

Output image, but careful observation can be found that in the output image of two (with the Red Line circled part) obvious hair loss of more places, the first scheme failed.

Option two: Next try the Channel method:

Observe three channels can be found, because the monkey's hair edge has two colors, from the yellow coil out of the section, in the red channel, you can pull out "white hair", in the blue channel, you can pull out "black hair." Pull out the two layers together and you're done.

Figure 04

Look at the plucked image, the edge of the hair is clear, however, the background is gray (the load of the layer does not have the background part, but why the gray background will appear in the copy layer, I have not understood.) The second plan declares defeat!

Option three: Only use the "extraction method" to try it:

In this material, because the monkey hair on the edge of "black, white" two, so consider two steps to pull out the hair. The steps are as follows:

1, first copy the background layer, press ctrl+alt+x, pull out the command. Dye the entire "monkey body" to a high light, note that the "force foreground" option is selected, and the first step is to draw white. Press "OK" to pull out the white hair.

2, "Layer One" is to pull out the white hair, in order to facilitate observation, add a dark green background layer. It can be seen that the hair is still very ideal.

3, and then copy the background layer again.

4, press ctrl+alt+x, pull out the order. This time, change the color of the "force foreground" option to "black." Press "OK" to pull out the black hair.

5, the dark green background layer to adjust to the "black hair" layer below, see the Monkey body hair edge root clear.

6, turn off the original background layer and dark green background of the eyes, the purpose is to confirm whether there is still a "gray" background phenomenon. You can see that the background is transparent.

7, the next "white hair layer" and "black hair layer" together, in the merged layer with a history pen to draw the main part of the monkey. So far, the monkey body's pull image has been successfully completed.
