How to Remove the Background from an Image: A Step-by-Step Guide7

Removing the background from an image is a common task in photo editing. Whether you're creating a composite image, adding a new background, or simply isolating a subject, knowing how to 抠图 (cut out) an image can be incredibly useful.

While there are a number of different ways to 抠图 an image, in this tutorial, we'll cover one of the most common and straightforward methods: using the Pen Tool in Adobe Photoshop.

Step 1: Open the Image in Photoshop

The first step is to open the image you want to 抠图 in Photoshop.

Step 2: Create a Layer Mask

Creating a layer mask will allow you to make changes to the background without affecting the original image. To create a layer mask, click on the "Add Layer Mask" button at the bottom of the Layers panel.

Step 3: Select the Pen Tool

Next, select the Pen Tool from the Tools panel. The Pen Tool is used to create precise paths, which we will use to define the edges of the subject we want to 抠图.

Step 4: Trace the Outline of the Subject

Using the Pen Tool, start tracing the outline of the subject you want to 抠图. To create a point, click on the canvas. To create a curved segment, click and drag on the canvas. To create a smooth curve, hold down the Shift key while dragging.

Step 5: Close the Path

Once you have traced around the subject, click on the first point you created to close the path.

Step 6: Create a Selection

With the path selected, go to Select > Make Selection. This will create a selection around the subject based on the path you created.

Step 7: Invert the Selection

Next, invert the selection by pressing Ctrl + Shift + I (Windows) or Command + Shift + I (Mac). This will select the background instead of the subject.

Step 8: Delete the Background

With the background selected, press Delete to remove it from the image.

Step 9: Refine the Edges (Optional)

If necessary, you can refine the edges of the 抠图 using a tool such as the Refine Edge Brush Tool.

Step 10: Save the Image

Once you are satisfied with the抠图, save the image in your desired format.

Tips for Better 抠图* Use a high-quality image. The higher the quality of the image, the easier it will be to抠图.
* Take your time.抠图是一个需要耐心和精确的过程。不要匆忙，否则你可能会犯错误。
* Use the right tools. The Pen Tool is a great tool for抠图，但也有其他工具可以帮助你，比如快速选择工具或魔棒工具。
* Experiment with different settings. The settings you use for抠图将根据图像而有所不同。不要害怕尝试不同的设置，直到你找到最适合你的设置。
