Graph deduction strategy in FW (4)-for FW beginners (black and white backgrounds with black hair)

The title is a little too long, so there is no way to do it. If you don't know it clearly, someone will say that you write things to harm beginners. The hair deduction series was originally intended to be discussed after the wedding dress is finished. However, since the Wolf said a color order button, we will temporarily disrupt the order, let's take a look at some other methods that may be used for graph deduction,

Hair deduction is a headache. To make it clear, I divided my hair deduction type into four categories (I only want to see four types ):
The first is: black hair with black and white background effects; the second is: black hair with non-black and white background Effects close to solid color; the third is: non-black hair with a single background color; the fourth is: buckle the hair with a background color that is close to the hair color. I personally think that the difficulty coefficient of these types is gradually increasing. In the next several tutorials, I will introduce the first three graph deduction methods in sequence. As for the fourth method, no good solution has been found in FW. I will stay for further study!

In this example, the first type is the simplest.
In this example, a "filter" -- "convert to Alpha" is used. Do not underestimate this filter. If it is just a single black/white background, through the use of such a small filter effect, we can achieve the expected deduction.

Well, as shown in the example, before the tutorial starts, Let's first look at the material graph to be processed:

1. Before the graph deduction starts, make a good habit of copying two new layers on the layer board to hide and lock the source image layer.

2. Select the top layer and use the lock tool to outline the topic outline of the character. That is to say, all the other parts can be selected as much as possible except for the flying hair, remove unnecessary parts as much as possible. (For free operations on the selection area, remember to use the Shift key and ctrl key flexibly !)

3. After the selection is complete, press the "Ctrl + Shift + I" shortcut key to achieve the inverse selection of the selection, and then press the "Del" key to delete the selection. Then, you can hide the layer on the panel for subsequent operations.
4. Select the layer object in the middle and select the filter | others | convert to Alpha Command on the property panel.

5. Change the top layer object to visible. Add a background and check the effect!

Okay, close! Easy!
