method of drawing PS channel
Processing pictures, pull the map is often encountered problems, for the edge of neat, pixel contrast strong, you can use magic wand or path tool to pull map processing. But for the characters fluttering long hair, with these tools will not be the start. In fact, there are many ways to pull the map, different pictures have different pull method. Here I recommend one of the most commonly used and most effective method--channel-pull method.
Tip: Channel-pull method is to use the picture itself channel information to select the part that needs to be plucked.
1. Start Photoshop, import the pictures you want to work with, click the Pen tool, property settings
Check out the body outline of the character in the picture. Note that the broken part should not be hooked up, as it will be processed specifically at a later.
Tips: When using the "pen" tool to hook the picture, slightly to the point, so that the final finished product will not have a miscellaneous edge appearance.
2. Choose window → path to open the path panel, at which point you will find a "working path" in the path panel, and click the "Load path as a selection" button to convert the closed path to a selection.
3. Select "window → layer" to open the Layers panel, click on the "Background" layer, right-click the "Copy Layer" command, a new "background copy." Click "Background Copy" and the "Add Layer Mask" button
