Image processing: Photoshop7.0 figure-digging combat

Most digital photos need some post-processing, if you want to play deceitful act or change the background of the magic, it must be inseparable from the pull map. A lot of novice Photoshop friends are in order to pull out a headache, remember the first time I pick up the picture will only use magic wand and rubber tools, the result of a picture is always dizzy. There are two common ways to use Photoshop to pull a picture, one way is to use a channel, and the other is to use a filter. Using a channel to pull the map has many limitations, and still need to spend a lot of time to decorate, and use the filter to pull the map is simple and quick, pull the image of the effect is good. Photoshop 7.0 comes with an extract filter (shortcut key alt+ctrl+x) that is specifically designed to pull out the drawing, and it is most appropriate to use this filter to pick up hair or a complex background picture.

Here's an example of how to use the pull filter to get a picture, before we start by reminding you that using an extract filter will remove pixels from the part of the picture that are removed directly, and for the sake of safety, it is a good idea to copy the layer before using the pull filter. Open a picture after running Photoshop, select the extract command from the Filter menu, and open the Extract Filter control window as shown in (Figure 1). It can be seen that this picture has a complex background, a red tone for characters and backgrounds, and a troublesome feather scarf.

Let's take a look at the control window for the extraction filter, the toolbar on the left, and the control bar on the right. Activate the edge highlight in the Extract Filter window and tick the smart highlight check box. Select the part contour of the character as shown in Figure 2. Intelligent display of high light is a very practical function, can be very precise selection of characters and background color pairs of the more intense parts. Next, remove the smart Highlight check box, select the appropriate brush size, tick the hair and scarf section. Note that the brush size should not be too large or that some of the parts we need to keep will be removed, and the high light portion should include both the interior and exterior of the character contour. If the high light part is too large, you can use the Eraser tool to erase some of the high light, to ensure that the character profile is selected accurately. Finally, use the Fill tool to populate the part you want to pick up, as shown in Figure 3. Press the OK button, that's the simple part of the character is perfectly plucked out. Filling the background layer can better observe the effect of the pull, as shown in (Figure 4).

If you select too many high light portions in the previous operation, some parts of the character that you want to keep are also deleted. Even if there is no previous copy of the image there is a way to remedy the rubber tool after activating the ALT key, use the history eraser can be a person or a part of the background recovery.

In addition to the extraction filters described earlier, Photoshop has a few external filters that are specifically used to pull the map, such as knockout and Maskpro. Compared with the extraction filter, they are more powerful, the effect of drawing is better, interested friends can try. But we do not have to pull the map filter is not to learn hand-dug method, sometimes the basic skills more important
