A friend asked me how to pull a picture, how to pick my hair, because he wanted to change the white background of the registration photos to the blue bottom, before we go to the photo.

Well, also do not say too much crap, online on the technique of drawing is also said very much, I think as long as you can integrate PS knowledge, then to pull the map of such trivial matters, all for the clouds.

At the same time I also want to tell you that you want to learn PS, the theory must be indispensable, want to enter the high state of PS, break through their own bottlenecks, then in theory more than a little kung fu it.

Please remember the following points first:

In the case of 1,90%, the drawing is replaced by other more effective methods, and it is a matter of necessity.

One, background eraser.

In fact, the simplest tool to pull the map, no more than this. Find the eraser in the Toolbox, and then press and hold, you will see the background eraser, the background eraser name is good, as the definition is to wipe the background, but what is the background?

You first the tool, and then press "]" to enlarge the strokes, carefully observe you will find that the background eraser cursor at the beginning of a big circle, including a "ten" zigzag, is not very much like a target.

"Ten": is the middle of the cross, which is used to specify who is the background.

As a first step, we turn the background layer into layers (the difference between the background layer and the layer) and discuss it later.

Double-click the background in the layers panel, and then click OK. There's no lock in the back.

Look at my parameters and click in the picture

Watch my circle, my center is outside the hair. At this point, PS to the position of my center as a "background color", tolerance 50%, is the background color close to the surrounding a range. The bigger the color, the more it will be.

Then move the center of the circle to the hair and try to see the picture

Now the center is on top of the hair, so the black of the hair is erased as a background color. Category:
