When processing pictures, cutout is a common problem that everyone encounters. For those with neat edges and strong pixel contrast, you can use the magic wand or path Tools for cutout processing. But for characters with long hair, it’s impossible to use these tools. In fact, there are many ways to cut out pictures, and different pictures have different cutout methods. Below, the author recommends one of the most commonly used and most effective methods to everyone – the channel cutout method.
Tips: The channel cutout method uses the channel information of the image itself to select the part that needs to be cut out.
1. Start Photoshop, import the picture to be processed, click the “Pen” tool, and set the properties

Outline the main outline of the person in the picture. Be careful not to get the broken hair caught in it, as it will be specially processed later.
Tips: When using the “pen” tool to draw the picture, move it slightly inward so that there will be no edges in the final product.
2. Select “Window → Path” to open the “Path” panel. At this time, you will find that there is an additional “Working Path” in the Path panel. Click the “Load Path as Selection” button to close the path. Convert to selection.

3. Select “Window → Layers” to open the layers panel and click ” “Background” layer, right-click and click the “Copy Layer” command to create a new “Background Copy”. Select “Background Copy” and click the “Add Layer Mask” button

Tip: The layer mask has the advantage of being easy to change without destroying the original layer.

4. Select “Window → Channel” to open the “Channel” panel, drag the “green” channel to the “New” button under the channel panel, and make a copy

Tips: In principle, you should choose a channel with a large contrast between light and dark for copy processing. In this picture, the “blue” channel is smaller than the ” The “green” channel has a large contrast between light and dark, but due to picture quality reasons, the “blue” channel is lost, which will affect the final cutout effect. If the picture quality is very high, the “blue” channel is the best choice.
5. Click “Green Copy” and press the shortcut key Ctrl L to adjust the color levels. Pull the black slider on the left to the right and the white slider on the right to the left to reduce the midtones. , increase the shadows and highlights to make the hair and background well separated

6. Press the shortcut key Ctrl I to invert the “Green Copy” channel, click the “Brush” tool, and set the properties

Use a black paintbrush to paint the outside of the hair (that is, the areas that do not need to be selected) black, and then use a white paintbrush to paint the desired areas in the hair white.
7. Click the “Load Channel as Selection” button on the “Channel” panel to get the “Green Copy” selection.

8. Return to the “Layer” panel and double-click “Background” Layer” and change it to normal “Layer 0”

Tips: If there is a bad connection between the subject and the hair, you can use a black brush to process the mask. This is why I chose the layer mask at that time.
All the work is done now. Now you can paste the cutout into any background.

Tips: When changing the background for MM, pay attention to whether the direction of the background light source and the character’s lighting direction are consistent to ensure coordination and not look stiff.
